A High frequency Carrier Wave SPWM BSIT(or SITH) Frequency Converter

The paper describes a silent voltage source PWM frequency converter. Its main circuit uses novel full controlled devices bipolar static induction transistor(BSIT) and static induction thyristor(SITH). The system uses high frequency carrier wave SPWM configuration,to improve the property of the converter. In the paper, a drive circuit and the method for forming the high frequency carrier SPWM wave are proposed for both new devices. Finally, the experiment results are given.
