Zero-Voltage- and Zero-Current-Switching Full-Bridge Converter With Secondary Resonance
IEEE Transactions on Industrial Electronics, 2010 A zero-voltage- and zero-current-switching full-bridge (FB) converter with secondary resonance is presented and analyzed. The primary side of the converter is composed of FB insulated-gate bipolar transistors, which are driven by phase-shift control. The secondary side is composed of a resonant tank and a half-wave rectifier.

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.

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 ...

A novel interleaved boost converter with zero-voltage switching (ZVS) and zero-current switching (ZCS) characteristics is proposed in this paper. By using the interleaved approach, this topology not only decreases the current stress of the main circuit device but also reduces the ripple of the input current and output voltage. Moreover, by establishing

A zero-voltage and zero-current switching three-level DC/DC converter
IEEE Transactions on Power Electronics, 2002This paper presents a novel zero voltage and zero current switching (ZVZCS) three-Level (TL) DC/DC power converter. This converter overcomes the drawbacks presented by the conventional zero voltage switching (ZVS) three-level converter, such as high circulating energy, severe parasitic ringing on the rectifier diodes, and limited ZVS load range for the

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.
