【Abstract】 The basic topology and operating principles of a three phase single switch ZCS BUCK type of high factor rectifier are illustrated and the characteristics of resonant operating are analyzed in one switching period for providing design principles and parameter selections of the circuit. The experimental results and waveforms are verified on a 1 kVA prototype unit based on one cycle control.更多还原
