摘要：

A new family of DC-to-DC converters featuring clamping action, PWM modulation and soft-switching (ZVS) in both active and passive switches, is proposed to overcome the limitations of Clamped Mode DC-to-DC converters. The new family of converters is generated and the new circuits are presented, As the resonant circuits absorb all parasitic reactances, including transistor output capacitance and diode junction capacitance, these converters are suitable for high-frequency operation. Principle of operation, theoretical analysis, simulation and experimental results are presented, taken from a laboratory prototype rated at 1660W, input voltage of 300V, output voltage of 400V, and operating at 100kHz. The measured efficiency at full load was 98%.
