• active clamping
• dc-dc
• zero voltage switching (ZVS)

A new zero voltage switching (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 and the parasitic capacitance of the diode is eliminated, and therefore, the circulating loss is minimized. A new ZVS boost converter is presented and analyzed in detail to demonstrate the operating principle of the new ZVS cell. A new family of ZVS dc-dc converters can be derived based on the proposed ZVS cell and typical nonisolated dc-dc converters. A 500 W/190 kHz ZVS boost prototype is made to verify the analysis.
