New active clamp technique for switching losses reduction of MIC systems

Recently, the MIC system have been actively studied to reduce switching losses and improve its reliability and efficiency. The Active clamp Flyback converter is based on the Flyback converter topology. But, the Flyback converter generates the voltage spike between Drain and Source of the MOSFET device. This spike causes losses and noises of the converter. So, the Active clamp Flyback converter is studied the focus of the voltage spike reduction. In this paper, The New Active Clamp Fly-back Converter is proposed to improve the efficiency by the Power-Sim simulator and the experiment.
