摘要: A protection apparatus and a method of PWM cycloconverter wherein when the is shut off, surge voltage or an overcurrent not produced on output side are provided. made up fault detection means 30 for detecting cycloconverter, operation stop 25 turning off at least some uni-directional semiconductor switches 3 to 20 if signal occurs, continuous flow allowing load current continuously phases become open, switching 50 unidirectional based from means.
