Abstract
An asymmetrical pulse width modulation (APWM) soft-switching integrated boost full-bridge converter with high voltage gain is presented. In the presented converter, the boost-fed structure is utilized to provide a continuous input current. APWM full-bridge DC-DC converter with 2-stage voltage doubler in the proposed converter provides soft-switching characteristic of main switches and high voltage gain. Moreover, the leakage inductance of the transformer alleviates the reverse-recovery problems of the output diodes. The proposed converter achieves high efficiency because of mitigation of the output diodes' reverse recovery problem and soft-switching characteristic of main switches. Detailed analysis and design of the proposed converter are carried out. A prototype of the proposed converter is developed, and its experimental results are presented for validation.
