Zero-voltage-switching/zero-current-switching soft-switching dual-resonant converter

International Journal of Electronics, 2010
A soft-switching converter with dual resonant structures is presented in this article. The dual resonant tanks are composed of the leakage inductors and resonant capacitors to achieve a zero-current-switching (ZCS) turn-off mechanism for diodes on the secondary side of the transformer. Moreover, the voltage stresses of power switches are clamped by the

Zero voltage switching differential inverters

2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
This paper proposes a family of single-phase single-stage step-up/down ZVS inverters derived from adding an LC series resonant circuit to the conventional differential inverters and controlling them in such a way that ZVS happens for individual switches. Differential inverters are single-stage step-up/down inverters.

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.

Voltage fed zero-voltage zero-current switching PWM DC-DC converter

2008 13th International Power Electronics and Motion Control Conference, 2008
A new zero-voltage zero-current switching full-bridge phase-shifted PWM converter with controlled output rectifier is presented in this paper. IGBT switches are used in the high-frequency inverter of the DC-DC converter. Zero-voltage turn-on and zero-current turn-off for all power switches of the inverter is achieved for full load range from no-load to

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.

A zero voltage switching switched capacitor voltage doubler

2012 IEEE International Symposium on Industrial Electronics, 2012
Switched capacitor converter has advantages such as no magnetic components, compact size. With the target to reach high power, high switching frequency is preferred. In order to achieve high efficiency, soft switching becomes vital. This paper proposes a soft switched voltage doubler and its PWM scheme, with which, all switches in the converter turns ...

Zero-voltage-switching multi-resonant three-level converters

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
This paper proposes a family of zero-voltage-switching multiresonant three-level converters (ZVS-MR-TLCs), which are derived by adding a ZVS-MR multiresonant network to the TLCs. The arrangement of a multiresonant network results in the absorption of all the major parasitic components in the resonant circuit, including the switch output capacitor ...

A new zero voltage and zero current power switching technique

20th Annual IEEE Power Electronics Specialists Conference, 1992
An outline is presented of work done by the authors on a novel converter topology where the power switching occurs at both zero current and zero voltage, giving it some major advantage over the present state of the art. A description is given of the application of this topology to both high and low-output-voltage converters.

A primary-switched line-side converter using zero voltage switching

Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2001
A new primary-switched AC/DC power converter and its modulation are presented. It employs a single- or three-phase transformer, with a matrix converter (primary) and a conventional two-level converter (secondary). This allows galvanic isolation at medium-frequency zero-voltage primary commutation and five line-side voltage levels.

KY converter with zero voltage switching

2010 5th IEEE Conference on Industrial Electronics and Applications, 2010
In this paper, the soft switching technique is applied to the KY converter to upgrade the efficiency in the neighborhood of the rated load and hence enhance its capability in industrial applications. The details of soft switching of the KY converter are illustrated along with some simulated and experimental results to verify the effectiveness of the ...
