摘要
An improved zero-voltage-switching (ZVS) dc-dc converter with a high voltage gain and a ripple-free input current is proposed. It consists of two converter cells-a boost cell and an asymmetrical pulse-width-modulation (APWM) full-bridge cell. The boost cell in the proposed converter has the capabilities of providing a ripple-free input current. The APWM full-bridge cell provides a high voltage gain. The output diodes are under zero-current-switching (ZCS) during turn-off. The proposed converter has high efficiency due to soft-switching operation in full-bridge switches. Steady-state analysis of the converter is presented to determine the circuit parameters. A laboratory prototype of the proposed converter is developed, and its experimental results are presented for validation.
