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.

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.

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-Current-Switching Buck Converter

2019 International Conference on Electrical Drives & Power Electronics (EDPE), 2019
A 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

A comparative study of switching losses of IGBTs under hard-switching, zero-voltage-switching and zero-current-switching

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 ...

Zero-voltage switching in switched current circuits

Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002
Traditionally 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.

A new zero-current-switching constant switching frequency boost converter

1993 IEEE International Symposium on Circuits and Systems, 2002
The authors present a new boost topology which can be operated in constant switching frequency and zero-current-switching. In addition, the voltage stresses on the active switches are as low as the traditional boost pulse width modulated (PWM) converter. The control curves are derived through the normalized state-plane trajectory.

Analysis and Design of the Resonant Current of the LCLC Resonant Converters with Consideration of Zero-Voltage Switching and Zero-current Switching

2019 International Vacuum Electronics Conference (IVEC), 2019
The LCLC resonant converters are widely used in the Electronic Power Conditioner (EPC) in a Travelling-wave Tube Amplifier (TWTA) due to the advantage of Zero-Voltage-Switching (ZVS) and Zero-Current-Switching (ZCS). However, in the physical circuit, problems such as non-Zero-Current-Switching and reverse resonant current appear and the efficiency ...

A new zero current switching resonant Buck converter

2011 24th Canadian Conference on Electrical and Computer Engineering(CCECE), 2011
In this paper a zero current switching resonant Buck converter as a soft-switching DC-DC converter is presented In this buck type converter, all semiconductor elements are soft switched. Also, the converter benefits from a very simple control method. Theoretical equations are derived and confirmed through simulation results.
