• A soft-switching topology for high power buck converter is proposed. Zero-current turn-on and zero-voltage turn-off is achieved without auxiliary switches. All active switches in the converter transmit power to the load equally. Converter control is simple despite four active switches. Converter operation is described and DC analysis is carried out. All operation modes are identified. The condition for soft-switching is derived. A full-scale 38 kW laboratory prototype with 1700 V IGBT modules is built for railway application. Switching frequency is fixed at 20 kHz. Experimental results are shown. The results confirm the analysis. A high efficiency of 97 % is achieved.
