The paper presents a Two level half bridge dc- dc converter with reducing circulating losses. The proposedconverter can have the rectifier stage which is composed of four diodes in the center-tapped rectification. On the primaryside of the transformer, the two transformers are connected in series and the middle node of the two transformers isconnected to the neutral point of the split flying capacitors. Because it cooperates with the four-diode rectifier stage, thecirculating current on the primary side of the transformer decays to zero during the freewheeling period. The zerovoltage switching (ZVS) of the leading switches is it stores energy in the output filter inductor and the lagging switches isit stores energy in the magnetizing inductor of a transformer, rather than the energy stored in the leakage inductor. Thisproposed technique is ideal for an application which requires good performance and improves the efficiency. This paperdiscusses the brief analysis along with simulation results.
