New family of zero-current-switching PWM converters using a new zero-current-switching PWM auxiliary circuit

IEEE Transactions on Industrial Electronics, 2004
A new family of zero-current-switching (ZCS) pulsewidth-modulated (PWM) converters using a new ZCS-PWM auxiliary circuit is presented in this paper. The main switch and auxiliary switch operate at zero-current-switching turn on and turn off, and the all passive semiconductor devices in the ZCS-PWM converters operate at zero-voltage-switching (ZVS) turn

A new zero-current-switching constant switching frequency boost converter

1993 IEEE International Symposium on Circuits and Systems, 2002
The authors present a new boost topology which can be operated in constant switching frequency and zero-current-switching. In addition, the voltage stresses on the active switches are as low as the traditional boost pulse width modulated (PWM) converter. The control curves are derived through the normalized state-plane trajectory.

Class-E zero-voltage-switching and zero-current-switching rectifiers

IEEE Transactions on Circuits and Systems, 1990
A number of class-E, half-wave and full-wave, zero-voltage-switching (low dv/dt), zero-current-switching (low di/dt), and mixed-mode rectifiers are introduced and verified experimentally. The rectifiers are derived from conventional rectifiers by adding reactive components.

A zero-current-switching multilevel switched capacitor DC-DC converter

2011 IEEE Energy Conversion Congress and Exposition, 2011
This paper introduces a zero-current-switching multilevel switched capacitor dc-dc converter for use in high voltage gain and high temperature applications. This circuit has a reduced charge path, low switch count and low device ratings compared to many similar topologies. Furthermore, switching losses and component size are greatly reduced.

A family of zero current switching switched-capacitor dc-dc converters

2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010
This paper presents a new zero current switching (ZCS) technique for a family of switched-capacitor dc-dc converters. Compared to the traditional ZCS switched-capacitor dc-dc converters by inserting a magnetic core in the circuit, these new ZCS switched-capacitor dc-dc converters employ the stray inductance present in the circuit as the resonant ...

Switching losses of IGBTs under zero-voltage and zero-current switching

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
Turn-off switching losses of punch-through (PT) and nonpunch-through (NPT) IGBTs under hard switching (HS) and zero-voltage switching (ZVS) are presented and evaluated at 25/spl deg/C, 75/spl deg/C and 125/spl deg/C. A comparison between PT and NPT devices based on their internal device characteristics is given for HS and ZVS.

Multiple output zero-current switching switched-capacitor bidirectional dc–dc converter

International Journal of Electronics, 2010
The proposed circuit is a multiple output quasi-resonant (QR) zero-current switching (ZCS) switched-capacitor (SC) converter with a bidirectional power flow control conversion scheme. The principles of the proposed multiple output QR ZCS SC bidirectional dc–dc converter are described using a detailed circuit model for analysis.

Trench gate IGBTs for zero current switching applications

Eighteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2003. APEC '03., 2004
This paper reports on the behaviour of trench IGBTs in comparison with equivalent DMOS IGBTs in zero current switching converters. Extensive experimental results backed up by accurate Spice modelling are presented. These results indicate the superior performance of Trench IGBTs particularly at high switching frequencies, currents and junction ...

Zero-Current Switching Impedance-Source DC-DC Converter

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
This paper presents a novel soft-switching technique for the galvanically isolated impedance-source full-bridge DC-DC converters. It allows reducing the turn off losses of the inverter switches, which otherwise represent a significant portion of the total power loss in such converters.
