Zero Voltage Switching Converters

, 2000
In this paper zero voltage switching converters are investigated. The investigation starts by discussing the RCD charge-discharge snubber. The concept of resonant and quasi-resonant DC link converters is discussed.

An optimized scheme for OLTCs of distribution transformers using flywheel motors

Zhejiang dianli
In the switching process of on-load tap changers （OLTCs） for distribution transformers， electric arcs are likely to occur at the contacts， which have an adverse impact on the service life and normal operation of the equipment.

Role of induced exchange bias in zero field spin–orbit torque magnetization switching in Pt/[Ni/Co]/PtMn

AIP Advances, 2020
Current induced magnetization switching is of particular interest to develop non-volatile magnetic memories (MRAM). We studied spin–orbit torque (SOT) switching in a Pt/ferromagnet/antiferromagnet Pt/[Co/Ni]2/PtMn Hall cross. For the as-deposited sample,

Power Converter Possessing Zero-Voltage Switching and Output Isolation [PDF]

, 1995
A modified boost converter accomplishes power transfer to a load with an electrical isolation, a zero-voltage and a zero-current switching, a transformer core resetting mechanism, and component stresses identical to those in the conventional boost ...

Analysis of Intrinsic Switching Losses in Superjunction MOSFETs Under Zero Voltage Switching

Energies, 2020
Switching losses of power transistors usually are the most relevant energy losses in high-frequency power converters. Soft-switching techniques allow a reduction of these losses, but even under soft-switching conditions, these losses can be significant ...

A phase‐shift modulated series resonant converter achieving zero‐voltage and zero‐current switching for wide output voltage range battery charging applications

IET Power Electronics, 2022
In this article, a phase‐shift modulated zero‐voltage and zero‐current switching (ZVZCS) series resonant converter (SRC) was proposed for constant current (CC) and constant voltage (CV) charging operating at the series resonant frequency.

Study and Design of a Zero Voltage Switched Boost Converter [PDF]

, 2009
We study theoretical circuit operation of zero voltage switching over the basic premise of boost converters (step-up dc chopper circuits). Zero-voltage switching technique is studied which, in contrast to zero-current switching, eliminates the switching ...
