EQUIPMENT, METHODS, AND SYSTEMS FOR STABILIZING THE OUTPUT VOLTAGE OF A POWER SOURCE

Abstract

The invention relates to a device, method and system for regulating the output voltage of a power source (10). The power source (10) produces an output voltage based on the supply current. The device consists of a sampling module (11), a PID control module (12) and a control module (13). The sampling module (11) is configured to sample the output voltage of the power source (10) to obtain the sampled voltage (SI00). The PID control module (12) is configured to obtain the switching frequency signal by adjusting the PID control based on the sampled voltage and the pre-set control parameters. Adjusting the PID control includes adjusting the voltage loop control and adjusting the voltage difference rate loop control (S200). The control module (13) is configured to generate the current supply according to the switching frequency signal (S300). The output 011 voltage of the power source (10) can be implemented.
