Zero voltage switching approach for flyback converter

[Proceedings] Fourteenth International Telecommunications Energy Conference - INTELEC '92, 2003
A zero voltage switched flyback power converter which realizes soft switching for every semiconductor is proposed. The sinusoidal resonant current flows through the secondary side rectifier diode and zero current switching of the diode is realized. Diode recovery is not generated.

PWM boost converter with zero-voltage-switching

[Proceedings] 1992 IEEE International Conference on Systems, Man, and Cybernetics, 2003
By adding a second transistor, a zero-voltage-switched (ZVS) quasi-resonant boost converter can be shown to be controllable using a constant frequency control scheme. The new topology differs from a zero-voltage-switched quasi-resonant boost converter by the addition of an extra switch in parallel with the resonant inductor.

A novel zero voltage switched PWM converter

Proceedings of the 1992 International Conference on Industrial Electronics, Control, Instrumentation, and Automation, 2003
A novel approach to realizing zero voltage switching for high-frequency PWM (pulse-width modulation) power converters is presented. By controlling an auxiliary circuit associated with the main switching devices, these devices can be turned off at zero voltage condition.

A zero voltage switching switched capacitor voltage doubler

2012 IEEE International Symposium on Industrial Electronics, 2012
Switched 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 ...

Analysis of a Zero Voltage Switching Cuk Converter

IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society, 2007
A boost type zero voltage switching (ZVS) isolated Cuk converter is presented in this paper to reduce the switching losses of main switch. An auxiliary switch and a clamp capacitor are connected in parallel with the main switch to absorb all the energy stored in the leakage inductance of the transformer.

Zero-Voltage Switching in Full-Bridge Converter

Australian Journal of Electrical and Electronics Engineering, 2008
This paper presents a comparison study of circuit topology of the voltage source type zero-voltage soft-switching (ZVS) full-bridge DC-DC power converter with an isolated high-frequency transformer employing phase-shift control. The switching power losses and voltage stress on the active devices are considerably reduced. A prototype operating at 10kHz,

Zero-voltage-switched interleaved flyback converter

INTELEC 2009 - 31st International Telecommunications Energy Conference, 2009
This 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.

A novel zero-voltage switched multiresonant converter

PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 2002
A novel approach is presented by which the switching frequency of a two-transistor zero-voltage-switched multiresonant converter (ZVS-MRC) is controlled in proportion to input voltage changes in order to maintain essentially constant efficiency over the input voltage range with a switching variation of only +or-10%.
