Indeed, hard-switching direct current to (DC-DC) converters, commonly used industrial applications, pose significant risk the surrounding environment regarding compatibility (EMC). Usually, fast-switching phase induces...

In this paper, a single-switch ZVZCS quasi-resonant CLL isolated DC-DC converter for driving a low-ower (less than 100 W) 32” LED backlighting liquid crystal display television (LCD TV) is proposed. The proposed converter exhibits both forward and flyback operational characteristics. All semiconductors are activated and deactivated under the soft switching conditions during the switching transi...

This paper introduces a new soft switching boost converter with passive snubber. In the proposed converter, the main switch turns on under zero current switching (ZCS) and turns off under zero voltage switching (ZVS) without any additional voltage or current stresses. The main diode turns on under ZVS and turns off under ZCS. The proposed converter has features as low cost, simple control, low ...

This paper proposes a new passive snubber for enhancing the power conversion efficiency on a single phase ac-dc power factor correction (PFC) converter based on boost topology for battery charging systems. Soft switching can be achieved in the proposed converter with the proposed auxillary passive snubber circuit which is added to the conventional boost PFC converter. The converter switch is pr...

This paper proposes a new resonant gate driver circuit for a soft switching synchronous buck converter in a fixed load condition. The switching energy can be fully recovered during current commutation phase in the gate driver while the diode conduction losses in the low and high side switches can be substantially reduced by employing additional L and C resonant in the circuit. Using PSpice simu...
