New zero voltage switching PWM flyback converter

2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC), 2010
In this paper a new zero voltage switching PWM flyback converter with simple auxiliary circuit is introduced. The auxiliary circuit is only composed of a resonant capacitor and an auxiliary switch connected to a tertiary winding on the converter main transformer.

Zero Voltage Switching isolated boost converter topology

2011 IEEE 33rd International Telecommunications Energy Conference (INTELEC), 2011
This paper describes an isolated boost converter topology that was invented and patented by the author in the early 80s' but has not been described in detail in an article before. As this converter has very interesting properties and appears to now be re-invented by others perhaps it is time for a paper to be written on it.

GTO characterization for zero voltage switching applications

PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 2002
GTO applications limitations are investigated under hard and soft switching topologies as device output power and device switching frequency are simultaneously increased. Characterization test results and a P-Spice GTO model simulating device turn-off are used in the investigation.

A zero voltage switching forward converter topology

Proceedings of Power and Energy Systems in Converging Markets, 2002
A zero voltage switching forward converter topology is presented in this paper. The topology employs an auxiliary circuit. Only a few small rating components and devices are added. The merits of the proposed topology include: lossless switching independent of the input and load conditions, simple control and power circuitry, and ability to operate in ...

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.

Zero-voltage switching multi-output forward converter

INTELEC 2009 - 31st International Telecommunications Energy Conference, 2009
A new multi-output forward (MOFC) converter is proposed. It consists of four synchronous switches in secondary side for two outputs. The primary switches control the main output voltage and the synchronous switch in transformer secondary side controls the auxiliary output voltage.

A Novel Zero-Voltage-Switching PWM Full-Bridge Converter

2007 IEEE Power Electronics Specialists Conference, 2007
Introducing resonant inductance and clamping diodes into the full-bridge converter can eliminate the voltage oscillation across the rectifier diodes and increase the load range for zero- voltage-switching (ZVS) achievement. The resonant inductance is shorted and its current keeps constant when the clamping diode is conducting, and the clamping diodes ...

Single-switch zero-voltage-switching high power factor electronic ballast

2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003
This paper introduces two modified Class E circuits to achieve low crest factor of lamp current. By integrating flyback topology with Class E converter, the modified circuits can achieve improved lamp current crest factor, and still maintain high power factor and zero-voltage-switching features in conventional Class E converter.

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,
