Novel zero-current-switching-zero-voltage-switching converters
PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002A new family of zero-current-switching-zero-voltage-switching (ZCSZVS) pulse-width-modulation (PWM) converters are proposed. With the proposed ZCSZVS concept, the PSPICE simulation results of the application to a single-switch three-phase PFC rectifier have been obtained and compared with those of hard-switching and ZCT applications in order to show ...

Switching losses of IGBTs under zero-voltage and zero-current switching
PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002Turn-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.

Class-E zero-voltage-switching and zero-current-switching rectifiers
IEEE Transactions on Circuits and Systems, 1990A 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.

Zero-voltage-switching/zero-current-switching soft-switching dual-resonant converter
International Journal of Electronics, 2010A 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), 2015This 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.

KY converter with zero voltage switching
2010 5th IEEE Conference on Industrial Electronics and Applications, 2010In 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 ...

A zero voltage switching switched capacitor voltage doubler
2012 IEEE International Symposium on Industrial Electronics, 2012Switched 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 in switched current circuits
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002Traditionally the accuracy of switched-current circuits has been much lower than that of switched-capacitor circuits. To address this problem, an accurate high-speed switched-current sample-and-hold technique based on zero-voltage switching is presented.

Zero-voltage-switching multi-resonant three-level converters
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004This 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 ...
