A Soft-switching DC/DC converter with secondary phase shift control strategy is proposed in this paper. Zero-voltage-switching (ZVS) performance is achieved for all power devices, including the four primary MOSFETs, two secondary MOSFETs and diodes in a wide load range. The circulating current in the freewheeling stage is effectively suppressed to minimize the conduction losses. In addition, the voltage...
First, the limitations of the conventional interleaved boost converters in high-step-up and high-output-voltage applications are addressed in this paper. Then, a general derivation law of the nonisolated converters from their isolated counterparts is proposed and studied to give a universal solution for high-performance topology deduction. By employing the direct energy transfer concept, a family...
