Analysis and Design of Extended Range Zero Voltage Switching (ZVS) Active-Clamping Current-Fed Push-Pull Converter

摘要

This paper proposes extended soft-switched active-clamped type current-fed isolated push-pull voltage DC-DC converter. Proposed topology retains soft-switching for extended operating range. Steady-state analysis and simulation results are demonstrated. The turn-off voltage spike is eliminated. The higher load voltage is achieved with the help of voltage doubler on the load side. To validate the proposed analysis, design, and performance evaluation, simulation results are presented.
