Low-voltage on-board DC-DC converters are increasingly required to have high efficiency and fast transient response. In this paper, two-stage DC-DC converter architecture is proposed to achieve fast transient response while operating at high efficiencies, which feature soft switching, self-current-sharing capability and simplified self-driven ...

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

Zero-Voltage Switching Operation of Transformer Class-E Inverter at Any Coupling Coefficient
IEEE transactions on industrial electronics (1982. Print), 2019This paper presents a complete design methodology of a Class-E inverter with a loosely coupled transformer under zero-voltage switching conditions. At a selected maximum coupling coefficient, the inverter satisfies both zero-voltage switching (ZVS) and ...

This paper proposes extended soft-switched active-clamped type current-fed isolated push–pull voltage DC–DC converter. Proposed topology retains soft-switching for extended operating range. Steady-state analysis and simulation results are demonstrated. The turn-off voltage spike is eliminated.

2017 IEEE 3rd International Future Energy Electronics Conference and ECCE Asia (IFEEC 2017 - ECCE Asia), 2017
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 Zero Voltage Switching Topology for Non-Inverting Buck–Boost Converter
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2019This brief summarizes soft-switching methods for the non-inverting buck-boost converter (NIBBC). Then a new zero voltage switching (ZVS) NIBBC is proposed. This new NIBBC employs a triple coupled inductor, two resonant inductors, and two auxiliary diodes.
