Abstract

This paper presents A Zero-Voltage-Switching(ZVS) Three-Level DC/DC Converter using Primary Clamping Diodes. The Previous ZVS Three-Level DC/DC converter realizes ZVS for the switches with the use of the leakage inductance(or external resonant inductance) and the output capacitors of the switches, however the rectifier diodes suffer from recovery which results in oscillation and voltage spike. In order to solve this problem, this paper proposes a novel ZVS Three-Level DC/DC converter, which introduces two clamping diodes to the basic Three-Level converter to eliminate the oscillation and clamp the rectified voltage to the reflected input voltage.
