This paper proposes an adaptive voltage position (AVP) control method for the improved phase shift full bridge (PSFB) soft switching DC-DC converter. For the improved topology, clamping diodes and resonant inductor are added. All power Mosfets can achieve soft switching at full load conditions and since clamping di-odes are utilized, the voltage oscillation of the output rectifier diodes can be de-creased. In order to improve the output voltage response ability of the converter in the process of load conversion, An AVP control method based on output cur-rent feedback regulation is proposed. Working principle of the topology and control method are introduced. Small signal model and controller design process are analyzed. Performance of the proposed control method and topology are verified by a 500W simulation model.
