Research on Stepless On-load Voltage Regulation Method Based on Auxiliary Potential Transformer
Aiming at the problem that the output voltage of the on-load tap changer is poor and the real-time performance is poor, a stepless on-load voltage regulation method based on auxiliary potential transformer is proposed. In this method, the power is absorbed from the power grid by the rectifier circuit, and the inverter is controlled by the SHE-PWM technology through the DSP to generate the required voltage, which is connected to the power grid in series through the auxiliary potential transformer, so as to realize the stepless on-load voltage regulation.
