Zero-Voltage Switching Full-Bridge Converter With Reduced Filter Requirement and Wide ZVS Range for Variable Output Application

open access: closedIEEE Transactions on Industrial Electronics, 2022
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 ...

Analysis and Design of Extended Range Zero Voltage Switching (ZVS) Active-Clamping Current-Fed Push–Pull Converter

open access: closed, 2020
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.

A novel zero-voltage-switching (ZVS) boost converter by using a nonlinear magnetizing inductor of the transformer

open access: closedProceedings 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

A soft-switching synchronous buck converter for Zero Voltage Switching (ZVS) in light and full load conditions

open access: closed2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008
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 ...

A MHz zero voltage switching (ZVS) tapped-inductor buck converter for wide-input high step-down low-power applications

open access: closed2017 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 DC voltage notching scheme for zero voltage switching (ZVS) of PWM inverters

open access: closedProceedings of 1994 IEEE Industry Applications Society Annual Meeting, 2002
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.
