This paper presents a new nonisolated asymmetrical buck voltage regulator module. A transformer is used to extend the extremely low duty cycle of a conventional buck converter. Turn-off losses can be significantly reduced due to the extension of duty cycle, and there are no turn-on losses owing to the zero-voltage turn-on condition. At the same time, the voltage stress over the synchronous rectifier...
This paper presents a new resonant gate drive circuit that utilizes transformer leakage inductance as resonant component. The new gate driver circuit can drive a pair of MOSFETs, which can be used in both with same reference and different reference circuits such as MOSFETs in buck, bridge converters. Pulse controlled resonance is used to reduce the conduction loss of resonant circuit. Also it provides...
