Conducted Noise Reduction in Active clamp ZVS flyback converter using Random Pulse Width Modulation

RPWM 기법을 이용한 능동클램프 ZVS 플라이백 컨버터 전도노이즈저감

In the conventional PWM converter, high-frequency switching techniques was used for high-density of energy, but occurred a lot of problems such as switching losses, switching voltage/current stresses, EMI(Electromgnetic Interference) and so on. To overcome these problems, various soft switching techniques have been presented. However these techniques are focused on reducing switching losses and voltage/current stresses . The simulation and experimental results are shown that the active clamp ZVS flyback converter with the proposed RPWM(Random Pulse Width Modulation) technique reduces the conducted noise.
