A simple zero-voltage-switching boost converter

Proceedings IEEE Southeastcon '98 'Engineering for a New Era', 2002
In this paper, a new type of PWM boost zero-voltage-switching converter is presented. The new soft-switching converter is formed by adding only two auxiliary components to a conventional boost converter, namely: an active switch and a resonant inductor. The voltage stresses on both the main and auxiliary switches are fixed at V/sub g/+V/sub o/ and they

Zero voltage switching series resonant based UPS

PESC 98 Record. 29th Annual IEEE Power Electronics Specialists Conference (Cat. No.98CH36196), 2002
This paper presents a novel single-phase UPS topology based on series resonant power converters. Among the features of the proposed topology are: (i) zero voltage switching for all power converters that comprise the UPS; (ii) inherent protection against short-circuits in the load; (iii) high quality output waveforms even when operating at no load or ...

Multiple-Phase-Shift Control for a Dual Active Bridge to Secure Zero-Voltage Switching and Enhance Light-Load Performance

IEEE transactions on power electronics, 2018
An ac/dc + dual active bridge (DAB) circuit was found as one solution for the high-efficiency and high-power-density electric vehicle charger. One control option is to let the ac/dc part only convert the grid voltage to a double-line-frequency folded ...

A Zero Voltage Switching Topology for Non-Inverting Buck–Boost Converter

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2019
This 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.
