The double-loop control is a common method for controlling the inverter power supply, the power supply can still ensure relatively stable output under various disturbances through the double-loop control, and other functions of the inverter power supply, such as overcurrent protection, output voltage regulation, output current regulation and the like, are realized through the double-loop control. The double-loop control generally comprises a voltage outer loop and a current inner loop, wherein the voltage outer loop outputs instantaneous comparison current according to preset reference voltage and instantaneous output voltage of the inverter, and the current inner loop adjusts the instantaneous output current by taking the smaller value of the instantaneous comparison current and the preset maximum current as a target value, so that a control signal for controlling the output voltage of the inverter is output.

However, adjusting the instantaneous output current by using the smaller value of the instantaneous comparison current and the preset maximum current as the target value may cause the peak of the instantaneous output current to be truncated, thereby causing the waveform of the instantaneous output current to be distorted and affecting the control effect of the control signal.

An application scenario of the dual-loop control method provided in the embodiment of the present application is illustrated below. A load such as a motor usually generates a large current at the moment of energization, which is a rush current. Taking the motor as an example, when the motor is connected with a large power grid (or a large-capacity power supply) and is powered by the large power grid, the generated impact current cannot influence the large power grid. However, when the motor is connected with a low-capacity power supply and the low-capacity power supply supplies power, the impact current generated by switching on the motor is very large, and if the impact current exceeds the capacity of the power supply, the power supply is damaged, and the risk of power failure is caused. When the motor is connected with a small-capacity ac inverter, in order to reduce the inrush current, the output current of the ac inverter is usually measured when the motor is powered on, and if the output current exceeds a threshold, for example, 10A, the output voltage of the power supply is reduced to reduce the output current of the power supply, and until the output current is smaller than the threshold, the output voltage of the power supply is increased to reduce the inrush current.
