Abstract

The application provides a double-loop control method, device, electronic equipment and storage medium, relating to the field of circuits. The method includes: determining the adjustment coefficient according to the maximum instantaneous comparison current and the preset maximum current in the previous cycle of the instantaneous output voltage; taking the smaller value of the product of the instantaneous comparison current and the adjustment coefficient and the preset maximum current as the target value; according to the preset proportional coefficient, the target value and the instantaneous output current to generate an instantaneous control signal, compared with the prior art that directly uses the smaller value of the instantaneous comparison current and the preset maximum current as the target value to adjust the instantaneous output current, It can improve the degree to which the peak of the instantaneous output current is clipped, thereby reducing waveform distortion and improving the control effect of the control signal.

Description

technical field [0001] The present application relates to the circuit field, and in particular, relates to a double-loop control method, device, electronic equipment, and storage medium. Background technique [0002] Double-loop control is a commonly used method to control inverter power supply. Through double-loop control, the power supply can still guarantee a relatively stable output under various disturbances. Other functions of the inverter power supply, such as over-current protection, output voltage regulation, output current Functions such as adjustment are also realized through double-loop control. [0003] The double-loop control usually includes a voltage outer loop and a current inner loop. The voltage outer loop outputs an instantaneous comparison current according to the preset reference voltage and the instantaneous output voltage of the inverter power supply. The current inner loop will compare the instantaneous current and the smaller value of the preset max...
