Full-load-range-ZVS hybrid DC-DC converter with two full-bridges for high-power battery charging

A novel soft switching DC-DC power converter is proposed that is ideal for high-power battery charging applications. Its main advantages are zero-switching under all operating conditions without significant conduction loss penalty, and significantly lower filter requirement compared to conventional power converters. The application of the proposed converter for high-power battery charging is discussed along with simulation and experimental results.
