In this paper, a novel zero-voltage switching (ZVS) full-bridge converter is proposed to overcome the disadvantages of traditional phase-shifted full-bridge (PSFB) converter. In the proposed converter, a half-bridge (HB) converter with center-tap rectifier (CTR) is integrated into the traditional PSFB converter by sharing the lagging-leg switches and ...

A technique using a nonlinear magnetizing inductor of the transformer is proposed to achieve zero-voltage-switching (ZVS) operation. ZVS and proper transformer core reset can be realized from the resonance that exists between the parasitic capacitance and the magnetizing inductance of the transformer. DC bias current applied to the transformer makes it

This paper proposes a new soft switching synchronous Buck converter to provide complete ZVS conditions for both high and low side MOSFETs under the light- or no-load, as well as full load conditions. In the continuous conduction mode (CCM) with a heavy load current condition, the high side MOSFET is generally turned ON while the body diode of low side ...

In this paper, a tapped-inductor (TI) buck converter using planar coupled inductor is presented for low power applications. The duty cycle of TI buck is much wider compared with traditional buck converter under same voltage conversion ratio conditions. Therefore, it is suitable for high step-down applications. With synchronous conduction mode (SCM), TI

A DC voltage notching scheme for zero voltage switching (ZVS) of PWM inverters
This paper presents a DC voltage notching scheme for zero voltage switching (ZVS) of PWM inverters. The proposed scheme permits programmed DC voltage notching, i.e. the DC voltage can be brought to zero on command to facilitate ZVS of the inverter switches.
