In the light of excessive switching device in AC stabilizer power supply and the complex circuit control,a new unipolar AC stabilizer chopper circuit topology is proposed.The circuit construction and control mode have lots of merits, simple,fast dynamic response ,little switching device,low harmonic wave content, little capacitance of filter capacitor and inductor, high output precision.The circuit adopts PWM chopper control mode, power factor on the system side is close to 1. Good simulation and model experiment demonstrate that the device has a large utility value.
