Technical Field

The invention relates to a generator, in particular to a generator manufactured by utilizing an electromagnetic induction principle.

Background

The magnetic field of the induced current always hinders the change of the magnetic flux causing the induced current.

A high permeability material refers to a ferromagnetic material having a permeability above about 100.

The high-permeability material can transmit the changed magnetic field to other places, for example, an iron core of the transformer can transmit the changed magnetic field from the input coil to the vicinity of the coil outputting the electric energy, so that the coil outputting the electric energy outputs the electric energy outwards due to the generation of induced electromotive force.

Disclosure of Invention

Assuming that a magnetic field a exists around a conductor B, the conductor B performs magnetic induction line motion of cutting the magnetic field a, dynamic electromotive force is generated in the conductor B, when the conductor B is connected with a load, current is generated in the conductor B, and the magnetic field generated by the current in the conductor B obstructs the motion of the conductor B, so that the obstruction effect of the magnetic field a on the conductor B can be reduced by reducing the magnetic field intensity of the magnetic field generated by the current in the conductor B. If the load input current that conductor B connects is when pulse current, conductor B can produce the magnetic field of change, if when conductor C utilized the magnetic field of change that conductor B produced to produce induced current, can know by lenz's law, conductor C can produce the magnetic field that hinders conductor B magnetic field change for magnetic field A reduces conductor B's hindrance effect, and conductor C's electric energy we can be taken to drive other electrical apparatus work again, and then improve generator mechanical efficiency.

In order to enable a changing magnetic field generated by the conductor B to be transmitted to the vicinity of the conductor C, the conductor B cuts a magnetic induction line, a part for converting kinetic energy into electric energy is attached to a high-permeability material, and the rest part is far away from the high-permeability material. Because the magnetic conductivity of the high-permeability material is very high, the conductor B cuts magnetic induction lines, and a changing magnetic field generated by a part for converting kinetic energy into electric energy is transmitted to the vicinity of the conductor C through the high-permeability material, so that the conductor C works by utilizing the changing magnetic field in the high-permeability material.

In order to realize the technical scheme, the invention provides a power generation method which is specifically characterized by comprising the following steps of:

one coil generates dynamic electromotive force due to the fact that a part of the conductor cuts the magnetic induction line, the coil is connected with a device with pulse current as input current, the part of the coil cutting the magnetic induction line, which converts kinetic energy into electric energy, is tightly attached to the material with high magnetic conductivity, the rest part of the coil cutting the magnetic induction line is far away from the material with high magnetic conductivity, the magnetic field intensity and the magnetic field direction of a static magnetic field generated by the magnet around the material with high magnetic conductivity are not changed, and the other coil outputs electric energy to the outside mainly depending on the magnetic field generated by the material with high magnetic conductivity.

In the invention, the magnetic field strength and the magnetic field direction of the static magnetic field generated by the magnet around the high-permeability material are not changed, so that the changed magnetic field in the high-permeability material is avoided due to the change of the static magnetic field generated by the magnet around the high-permeability material.

In order to achieve the above object, as shown in fig. 1 and 2 in the drawings of the specification, the magnet in the device is a ring magnet, a gap is formed inside a coil generating electromotive force by cutting magnetic induction lines, the magnet is arranged, the magnet is not in contact with the coil, the magnet keeps circular motion, and the high-permeability material and the coil keep static. The reason for making the magnet annular is to make the magnet cut the magnetic induction line to do circular motion, and when the high magnetic conductivity material and the coil are kept still, the magnetic field intensity and the magnetic field direction of the static magnetic field generated by the magnet around the high magnetic conductivity material are not changed. The coil which generates dynamic electromotive force due to cutting of the magnetic induction lines is internally provided with a gap so as to be capable of placing a magnet, and the magnet cuts the magnetic induction lines due to movement of the magnet. Meanwhile, when the magnet is arranged in the coil, as shown in the attached drawing of the specification, fig. 1 and fig. 2, the uppermost conductor can convert part of electric energy into kinetic energy, the kinetic energy consumed by the rotation of the magnet is reduced, and meanwhile, because the distance from the uppermost conductor to the magnet is longer than that from the lowermost conductor to the magnet, the coil which generates dynamic electromotive force due to the cutting of magnetic induction lines can output electric energy outwards when the magnet moves circumferentially.

The device for inputting pulse current consists of a load, a semiconductor switch device and a circuit for controlling the semiconductor switch device to be switched on and off, wherein the semiconductor switch is connected with the load in series, the load is connected with a coil in series, and the coil outputs the pulse current by controlling the semiconductor switch device to be switched on and off. When the semiconductor switch device is switched on, the current is large, and when the semiconductor switch device is switched off, the current is small, so that the semiconductor switch device is switched on and off at a certain frequency, and the input current of the device can be pulse current.

According to the invention, when the number of pulses output by the coil generating electromotive force per second due to the fact that a part of the conductor cuts the magnetic induction lines is less than 1000, the high-permeability material is composed of silicon steel sheets, and when the number of pulses output by the coil per second is more than 1000, the high-permeability material is a ferrite magnetic core. The reason is that silicon steel has high permeability, high resistance and low hysteresis loss in a magnetic field varying at a low frequency, but since silicon steel has larger eddy current loss in a magnetic field varying at a high frequency than a ferrite core, which has high permeability in a magnetic field varying at a high frequency, the ferrite core is used at a high frequency

The invention mainly depends on the coil which outputs electric energy to the outside by the magnetic field which is changed by the high magnetic conductivity material to be wound on the high magnetic conductivity material, so that the coil obtains energy due to the magnetic field which is changed by the high magnetic conductivity material

The coil which outputs electric energy to the outside mainly by the magnetic field which is changed by the high-permeability material is far away from the magnet or is positioned near the gravity center of the ring magnet, so that the influence of the circular motion of the magnet on the coil which outputs electric energy to the outside mainly by the magnetic field which is changed by the high-permeability material is avoided.

The coil which outputs electric energy to the outside mainly depends on the magnetic field which is changed by the high-permeability material is connected with the load, so as to transmit the electric energy to the load.

When a part of conductors in the coil cut the magnetic induction lines to generate dynamic electromotive force, the coil is connected with a device with pulse current input current, and the coil can generate electric energy and output the electric energy to the device with pulse current input current, so that the coil can output pulse current.

The semiconductor switch device is a triode or an MOS tube, and the conduction and the disconnection of the semiconductor switch device are controlled by controlling the bias of the base electrode of the triode or the grid electrode of the MOS tube so that the coil outputs pulse current.

Detailed Description

First, we place the coil, magnet, high magnetic permeability material in the position shown in fig. 1 and fig. 2, the magnet in the generator is a ring magnet, there is a gap inside the coil generating electromotive force by cutting magnetic induction lines, there is a magnet, and the magnet and the coil are not in contact. The coil is connected with a device which takes input current as pulse current, the part which converts kinetic energy into electric energy by cutting the magnetic induction line by the coil is clung to the material with high magnetic conductivity, the rest part is far away from the material with high magnetic conductivity, the magnetic field intensity and the magnetic field direction of the static magnetic field generated by the magnet around the material with high magnetic conductivity are not changed, and the other coil outputs electric energy to the outside mainly by the magnetic field which is generated by the material with high magnetic conductivity and changes.

The coil which outputs electric energy outwards mainly depends on the magnetic field which is changed by the high-permeability material in the generator and is far away from the magnet or is positioned near the gravity center of the ring magnet, and the coil which outputs energy outwards mainly depends on the magnetic field which is changed by the high-permeability material is connected with a load.

The coil which generates dynamic electromotive force due to cutting of the magnetic induction lines is internally provided with a gap so as to be capable of placing a magnet, and the magnet cuts the magnetic induction lines due to movement of the magnet. Meanwhile, when the magnet is arranged in the coil, as shown in the attached drawing of the specification, fig. 1 and fig. 2, the uppermost conductor can convert part of electric energy into kinetic energy, the kinetic energy consumed by the rotation of the magnet is reduced, and meanwhile, because the distance from the uppermost conductor to the magnet is longer than that from the lowermost conductor to the magnet, the coil which generates dynamic electromotive force due to the cutting of magnetic induction lines can output electric energy outwards when the magnet moves circumferentially. Let the magnet not contact the coil.

In this embodiment, the frequency of the pulse current output from the coil generating electromotive force by cutting the magnetic induction line is 60KHZ, and since the frequency of the output pulse current is high, a ferrite core is used as a high-permeability material. Since the mass of high permeability material we consume decreases as the frequency of the pulse current in the coil increases.

In this embodiment, as shown in fig. 4, a coil generating electromotive force by cutting a magnetic induction line by a part of a conductor is connected to a transistor, and a PWM signal generator is used to change the bias of the base of the transistor, so that the current output from the coil generating electromotive force by cutting a magnetic induction line by a part of a conductor is a pulse current. Then, the current output by the two coils in the generator is changed into constant-voltage direct current through the rectifying circuit and the filter circuit, then the output of the two filter circuits is connected in series to jointly supply power for the electric energy distribution system, and the electric energy distribution system supplies power for an electric appliance, a motor for controlling the circumferential motion speed of the magnet, the super capacitor and the PWM signal generator.

In order to conveniently realize the purpose of keeping the magnet movement speed stable by adjusting the power of the motor for controlling the magnet circular movement speed, the electric energy distribution system is required to output electric energy to the motor for controlling the magnet circular movement speed, so that the movement of the device can be ensured.

In order to drive the magnet to move, the embodiment needs a motor for controlling the circular movement speed of the magnet, a rotating shaft of the motor is connected with a gear, a gear is adhered to the surface of the magnet, and the gear adhered to the surface of the magnet is driven by the gear connected with the motor to control the movement speed of the magnet.

The principle of controlling the magnet by the motor for controlling the circular motion speed of the magnet is that the faster the motion speed of the magnet is, the higher the voltage output by the coil is. The larger the coil output voltage is, the larger the filter circuit output voltage is. The electric energy distribution system can judge the magnet movement speed according to the voltage transmitted by the filter circuit, when the magnet movement speed is too slow, the electric energy distribution system outputs more electric energy to the motor for controlling the magnet circular movement speed, and when the magnet movement speed is too fast, the electric energy output by the electric energy distribution system to the motor for controlling the magnet circular movement speed is reduced. The uniform-speed circular motion of the magnet is realized by adjusting the power of a motor for controlling the circular motion speed of the magnet.

In the method for simultaneously providing energy for the voltage distribution system by the two filter circuits in the embodiment, the two filter circuit outputs are connected in series, and the two filter circuits jointly supply power for the electric energy distribution system.

In the embodiment, the adjustment of the power of the motor for controlling the circumferential movement speed of the magnet is realized by a pulse width modulation technology. The motor power can be adjusted by adjusting the duty cycle of the pulse voltage input by the motor.

The rectifying circuit shown in fig. 4 of this embodiment is used to convert ac into dc, and the rectifying circuit used in this embodiment is a full-wave rectifying circuit or a full-wave bridge rectifying circuit. The purpose is in order to make full use of the different electric energy of voltage direction in the coil.

The filter circuit shown in fig. 4 of this embodiment is used to convert dc into constant voltage dc, where constant voltage dc refers to dc with relatively stable voltage and less voltage fluctuation, because ac cannot be converted into dc without ac component. The outputs of the two filter circuits can be connected in series and can jointly provide electric energy for the electric energy distribution system.

The PWM signal generator shown in fig. 4 of this embodiment is used to generate a pulse current, and the PWM signal generator is connected to the transistor, so that the PWM signal generator changes the bias of the base of the transistor at a certain frequency, and then the transistor is turned on and off at a certain frequency, and further, the current output from the coil, which generates electromotive force by cutting the magnetic induction line with a part of the conductor, is the pulse current.

In this embodiment, as shown in fig. 4, the core component of the electric energy distribution system is composed of four parts, namely, a voltage stabilizing transformer, a filter circuit output voltage monitoring system, a super capacitor voltage monitoring system, and a pulse width modulation circuit, wherein the voltage stabilizing transformer allows the transformer to generate a voltage which is maintained at a value close to a certain value, and the pulse width modulation circuit adjusts the power output by the electric energy distribution system by adjusting the duty ratio of the output pulse current. The filter circuit output voltage monitoring system is mainly used for enabling the system to know the movement speed of the magnet by monitoring the output voltage of the filter circuit, and the pulse width modulation circuit is convenient to adjust the power of the motor for controlling the circular movement speed of the magnet by adjusting the duty ratio. The super capacitor monitoring system has the function that when the voltage of the super capacitor is lower than a certain value, the generator is automatically started to charge the capacitor. When the electric energy distribution system does not provide electric energy for the electric appliances and the super capacitor is fully charged, the super capacitor monitoring system turns off the generator.

The super capacitor shown in fig. 4 of this embodiment is used for supplying the energy required by the magnet from rest to rotation, and maintaining the normal operation of various circuits in the device when the moving speed of the magnet is very small or at rest.
