Hard-switching is typically used in most DC-DC converters, where transition of a power switch occurs when it still carries current and is subject to voltage at the same time. The hard-switching operation incurs high stress and switching losses to the device.

A novel zero voltage switching SVM (ZVS-SVM) controlled three-phase boost rectifier
Twentieth Annual IEEE Applied Power Electronics Conference and Exposition, 2005. APEC 2005., 2005A novel zero voltage switching SVM (ZVS-SVM) controlled three-phase boost rectifier is proposed. A branch composed of one active switch, one resonant inductor and one clamping capacitor is added to the six-switch boost rectifier. In addition, a novel space vector modulation (ZVS-SVM) for the rectifier is proposed.

Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95, 1995
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
