Novel zero-current-switching PWM converters

IEEE Transactions on Industrial Electronics, 1997
This paper presents a new family of pulsewidth-modulated (PWM) converters, featuring soft commutation of the semiconductors at zero current (ZC) in the transistors and zero voltage (ZV) in the rectifiers. Besides operating at constant frequency and with reduced commutation losses, these new converters have output characteristics similar to the hard ...

Zero-current-switching switched-capacitorconverters

IEE Proceedings - Electric Power Applications, 2001
The paper presents a family of zero-current-switching switched-capacitor circuits based on the classical multiswitch switched-capacitor converters. The family of circuits consists of three topologies and provides different voltage conversion ratios. All the power devices including switches and diodes in the circuit are zero-current switching.

The infeasibility of a zero-current switching class-E amplifier

IEEE Transactions on Circuits and Systems, 1990
It has been shown that a class-E amplifier can be configured to provide nearly 100% efficiency and zero-current or zero-voltage switching. A particular configuration, which supplies zero-current switching when the transistor output capacitance is zero, is considered for the case in which the transistor output capacitance is greater than zero.

A Family of True Zero Voltage Zero Current Switching (ZVZCS) Nonisolated Bidirectional DC–DC Converter With Wide Soft Switching Range

IEEE Transactions on Industrial Electronics, 2017
This paper proposes a true zero voltage zero current switching (ZVZCS) nonisolated bidirectional dc-dc converter with reduced component count. An auxiliary resonant network-which comprises of an inductor, capacitor, diode, and two switches-provides the ...

Inverting Zero-Current-Switching Buck Converter

2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC), 2021
A zero current switching (ZCS) inverting buck converter is presented. Due to ZCS, the switching losses of the converter are minimized. The converter passes through four modes. The modes of operation are explained by mathematical description and with the help of the phasor u-Zi diagram. The dimensioning of the devices is explained.
