This paper deals with the novel soft-switching inverter topology and its capability of high frequency switching technology to be applicable to the power conversion system. To realize the switching power supply in the MHz switching application, there are some problems to be solved. In order to overcome these problems, we propose the phase-shift controlled zero current switching (ZCS) inverter and its control scheme. This circuit has soft-switching capability in the MHz switching range by the ZCS circuit topology and can control the output power by the phase-shift controlled method. In addition, effectiveness of this circuit is confirmed by comparative experimental study between the conventional hard-switching circuit and proposed circuit.
