Technical Field

The invention relates to the technical field of power supplies, in particular to a method, a device and equipment for determining parameters of an RC integrator on an output inductor of a voltage regulator and a computer readable storage medium.

Background

With the increase of network data volume, the rapid development of new technologies such as artificial intelligence technology, internet of things and internet of vehicles, more strict requirements on the performance of the server are provided, greater requirements on data storage are provided, and greater tests on the reliability of the hard disk are provided. The power supply reliability of each module is an important support for data reliability. In order to ensure the power supply reliability, the Ripple (Ripple) of the power supply current should be reduced as much as possible.

In the current power supply scheme of a Voltage Regulator (VR), a Ripple Injection technology (Ripple Injection technology) is adopted to reduce the Ripple of the power supply and improve the stability of the power supply, and the current mainly adopted implementation scheme is to add an RC integrator to the output inductor of the Voltage Regulator.

Fig. 1 is a circuit diagram of an output circuit of a voltage regulator. Taking a voltage regulator model TPS53355 as an example, as shown in FIG. 1, the voltage regulator comprises an output inductor L1 and a voltage dividing resistor R_FB1And a voltage dividing resistor R_FB2An output capacitor C_OUTForming the end of the output circuit of the voltage regulator, V_OUTFB is a voltage feedback pin that feeds back the output voltage to the voltage regulator for connection to the voltage output of the load. Since the inductance characteristic is that the inductance value decreases as the inductor current increases, the ripple current of the output inductor L1 increases as the inductor current increases. On this basis, the output voltage is automatically adjusted by connecting an RC integrator consisting of a resistor Rr and a capacitor Cr in parallel at two ends of the output inductor L1, coupling the RC integrator TO a voltage feedback pin (TO FB) through a capacitor Cac, and coupling Ripple current variation of the output inductor L1 TO a voltage feedback receiving pin FB of the voltage regulator through a Ripple Injection loop (Ripple Injection Circuit).

The parameter settings of the resistor Rr and the capacitor Cr of the RC integrator determine the quality of the output voltage regulation effect. At present, the scheme for setting the parameters of the RC integrator is mainly to substitute factory parameters of the voltage regulator into a fixed relational expression for calculation to obtain a value of the resistor Rr and a value of the capacitor Cr.

It would be a technical problem to those skilled in the art to provide a more accurate solution for determining RC integrator parameters to reduce output voltage deviation.
