Commutation Processes in Multiresonant ZVS Bridge Converter

open access: yesAdvances in Electrical and Electronic Engineering, 2008
The analysis of the multiresonant ZVS DC/DC bridge converter is presented. The control system of the converter is basedon the method of frequency control at the constant time of transistor turn-off with a phase shift. The operation of the circuit is givenand the operating range of the converter is defined where ZVS switching operation is assured ...

A New ZVS Nonisolated Bidirectional DC-DC Converter with Minimal Auxiliary Element [PDF]

open access: yesJournal of Intelligent Procedures in Electrical Technology, 2013
In this paper, a new nonisolated bidirectional buck–boost dc–dc converter is introduced. The proposed converter can be operated under ZVS condition and fixed switching frequency regardless of the direction of power flow.

Determining matching capacitance for a variable distance WPT system considering ZVS

open access: yesAIP Advances
Wireless Power Transfer (WPT) systems are widely used today across various applications. Due to their interoperability, there are many instances where the receiver can vary, and consequently, the air gap may differ depending on the application.

Symmetry and Duality in ZCS and ZVS Quasi-Resonant Buck, Boost, and Buck–Boost DC–DC Converters

open access: yesEnergies
Quasi-resonant (QR) DC–DC converters with PWM control achieve soft switching by shaping the commutation transient through a local resonant process. This paper proposes a symmetry-based unified perspective on classical QR converters by interpreting zero ...
