Abstract :
A new ZVS cell is proposed based on the active clamping technique. With a small clamping diode in the cell the voltage ringing caused by the auxiliary inductor is eliminated, and the circulating loss is minimized. A new ZVS boost converter is presented and analyzed in detail to demonstrate the operation principle of the new ZVS cell. Utilizing this cell a new family of ZVS DC-DC converter can be constructed based on typical non-isolated DC-DC converters. A 500 W/200 kHz ZVS boost prototype is made to verify the analysis
