N2 - In this paper, a hybrid converter with a new clamp circuit is presented. This hybrid converter has the structure of combining a phase-shifted full-bridge (PSFB)converter with a half-bridge (HB)LLC converter. On the primary side, the lagging-leg of PSFB converter is shared by HB LLC converter. On the secondary side, the full-bridge rectifiers of two converters are connected in series. Due to the series-connected structure on the secondary side, this hybrid converter is suitable for high output voltage applications. In addition, by using a new center-tapped clamp circuit, which consists of two diodes and two capacitors with connected to the center of the transformer, the proposed converter can solve many drawbacks of PSFB converters in wide range of output voltage. Finally, the performance in efficiency, power density, and cost can be improved. In order to validate the feasibility of the proposed converter, a 3.3-kW prototype was tested.
