| Abstract(in English) | A novel self-excited ZVS half-bridge converter with a synchronous half-wave rectifier is presented. In this converter a secondary rectifier is composed of a single MOSFET. Multi-on-time control system stabilizes output voltage and independently controls each on-time of FETs to achieve the ZVS operation of all FETs. The rectified current waveform is shaped like a half sinusoidal wave and ZCS operation of the rectifier is performed to reduce conduction loss during deadtime period. We analyze a state equation and the ZVS/ZCS conditions of the rectifying switch. We show the proposed converter can reduce loss in rectifier as compared with the flyback converter with synchronous rectifier prepared the deadtime. In the experiment this converter achieves high efficiency of 95.6% at 15.5V/6Aoutput and efficiency of 93.4% at 15.5V/12A output. |
