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.

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 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-Current-Switching Buck Converter
2019 International Conference on Electrical Drives & Power Electronics (EDPE), 2019A zero current switching (ZCS) buck converter is presented. Due to ZCS, the switching losses of the converter are minimized. The converter passes through four modes. The modes of operation are explained by mathematical description and with the help of the phasor u-Zi diagram. The dimensioning of the devices is explained. The control of the converter is

Proceedings of 1994 Power Electronics Specialist Conference - PESC'94, 2002
A high power IGBT tester, based on the typical clamped inductive load circuit and incorporating zero-voltage-transition and zero-current-transition soft-switching schemes, has been developed. Both turn-on losses, including the losses associated with reverse recovery of the clamp (free-wheeling) diode, and turn-off losses are measured and compared for ...
