A Zero-Voltage Switching Three-Phase Inverter
IEEE Transactions on Power Electronics, 2014A new modulation scheme for the active clamping zero-voltage switching (ZVS) inverter is proposed. With the proposed modulation scheme, the inverter can realize ZVS operation in all switching devices and can remarkably suppress the reverse recovery current in insulated-gate bipolar transistor's antiparallel diodes as well.

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.

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 ...

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 ...

Zero-voltage-switched interleaved flyback converter
INTELEC 2009 - 31st International Telecommunications Energy Conference, 2009This paper proposes an interleaved flyback converter which is remarked with zero-voltage-switched active switches and reduced reverse recovery loss on the rectifying diodes. The configuration is composed of two identical flyback converters and an auxiliary inductor shunted between the diodes.

Charge control for zero-voltage-switching multiresonant converter
IEEE Transactions on Power Electronics, 1996The operation of zero-voltage-switching multi-resonant power converters (ZVSMRCs) limits the use of peak current-mode control. The charge control technique is found applicable to ZVSMRCs for improving dynamic performance. Charge control compares the total charge of the switch current to the control voltage to modulate the switching frequency. Since the

A new zero-voltage switching DC/DC boost converter
IEEE Transactions on Aerospace and Electronic Systems, 1993A pulsewidth-modulated (PWM) zero-voltage-switching quasi-resonant boost converter operating at constant switching frequency is presented. In contrast to the frequency-modulated (FM) zero-voltage-switching quasi-resonant boost converter, this converter possesses better controllability and higher operating performance, and overcomes the instability ...

A simple zero-voltage-switching boost converter
Proceedings IEEE Southeastcon '98 'Engineering for a New Era', 2002In this paper, a new type of PWM boost zero-voltage-switching converter is presented. The new soft-switching converter is formed by adding only two auxiliary components to a conventional boost converter, namely: an active switch and a resonant inductor. The voltage stresses on both the main and auxiliary switches are fixed at V/sub g/+V/sub o/ and they
