Abstract :
A new PWM AC-DC convertor with only one switching device is proposed. The control of the AC-DC convertor based on the PWM strategy to make the source current in phase with the source voltage is described, and a simple and practical input filter design is proposed. A comparative study between two proposed types of PWM AC-DC convertors and a new PWM AC-DC convertor with only one switching device, is carried out. The waveforms of voltage and current, the input and output characteristics, and the dynamic characteristics of the new PWM AC-DC convertor with only one switching device, are discussed and verified
