Abstract
This paper presents an improved ZVT DC-DC boost power converter using a regenerative snubber. The proposed snubber uses a magnetically coupled cell to reduce the turn-off switching loss of the auxiliary switch. The method has been employed to build a 500 W/100 kHz prototype. The experimental results show the ZVT DC-DC boost converter waveforms with and without the regenerative snubber. A high efficiency is achieved using the proposed improvement.
