| Abstract: | A new family of zero-current and zero-voltage switching(ZC-ZVS) pulse width-modulation(PWM) converters was proposed,based on a new ZC-ZVS PWM switch cell.The main switches operate at ZCS on and off,the auxiliary switches operate at ZVS on and off,and the passive semi-conductor devices in the ZC-ZVS converters operate at ZCS on and off.In addition to operating at constant frequency and reducing commutation losses,the new converters have no additional current stress or conduct loss in the main switch in compa... |
