摘要: A Zero-Voltage and Zero-Current Switching Full-Bridge Pulse Width Modulation (ZVZCS-FB-PWM) converter is proposed to improve the performance of existing with active clamp. The can eliminate switching loss clamp switch. Efficiency improved since switch operates at twice frequency. topology including circuit very simple minimum number components. Main switches are still fully soft switched while turn on under ZVZCS off ZVS. principle operation explained analyzed. simulation results justify analysis.
