Abstract
A novel zero voltage switching (ZVS) three-level (TL) DC/DC power converter is presented in this paper. The converter uses a flying capacitor in the primary side to allow operation with phase-shift control and in this way achieves ZVS for all the switches. The principle of operation of the converter is analyzed and verified on a 6 kW, 100 kHz experimental prototype. Additionally, this paper presents improvement of the proposed converter by using different ZVS techniques
