<Abstract>

This paper presents one configuration of the interleaved full-bridge?@converter. The proposed converter has the following advantages; 1. achieve zero-current-switching introducing resonant circuit, 2. achieve high-efficiencyoperation using isolated class E synchronous rectifier, 3. it is difficult to break for isolated rectifier. Also, it is easy to control phase-shift for regulating timing of switching operation and turn of combining transformer. We design the buck-converter in the presented circuit and show simulated waveform.
