Simulation of PSM high voltage power module based on compensation network

The regulation module of the high-voltage power supply system for lower hybrid current drive of the China Engineering Test Fusion Reactor (CFETR) is simulated on MATLAB platform. Impact of power grid fluctuations, load changes and filter parameters on the output voltage is analyzed in the static state. The compensation network can greatly reduce the ripple of the output voltage and increase its stability. The stabilization time of the system is within a few milliseconds, and the ripple factor is < 1%. The simulation results show that it is reasonable to adopt PID (proportional integral derivative) control and lead-lag compensation strategy for the high-voltage power system regulation module.
