On the basis of a single-phase PWM AC conversion circuit analysis, firstly the three-phase AC chopper circuit with 12-pulse rectifier design is completed under a given system parameter index; and then a system simulation model in Matlab/Simulink environment is built. The simulation results show that the DC power can respond quickly and has a stable output while the input voltage and the load changes. Finally, an experimental prototype is developed. Experimental results show that the output of this circuit is stable and highly precise, so as to verify its correctness and practicability.
