Three-level (TL) dc-dc converters can meet high input voltage requirement. The isolated TL converters with clamping diodes and flying capacitor are the prevalent TL topologies. However, large circulating current in the primary windings may degrade the efficiency. Although many other TL converters with auxiliary components are proposed and investigated for soft switching, the auxiliary components may...
An improved two-half-bridge cascaded three-level (TL) DC-DC converter with reduced circulating current is proposed in this paper. The converter contains two transformers but without clamping diodes or flying capacitors. The rectifier stage is composed of four diodes and four windings of the two transformers. Because of the proper sequence of the windings, the circulating currents on the primary side...
