Improved full bridge zero voltage switched phase shift DC/DC converter using a secondary clamped inductor

This paper presents the analysis, simulation and experimental results of a full-bridge zero voltage switched phase shift DC-DC power converter, working with an internal frequency of 250 kHz, with an output power of 1 kW. The power converter uses a two windings inductor with the secondary connected to the output by means of two clamping rectifier diodes, to allow resonant commutation of the passive to active leg of the power converter. With this process it is possible to improve the efficiency of the power converter.
