Abstract
A new soft recovery pulse width modulation quasi resonant converter composed only passive devices snubber network is proposed. This passive devices snubber network is revised form of folding snubber network that suppressed the reverse recovery current of main rectify diode in PWM converter. It also makes the MOSFET switching devices operate in soft state. The efficient of the proposed converter is almost same level to that of the converter of active snubber type. The overall circuit is simple and easy to realized. Therefore, it is suitable to apply to middle range output power source.
