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.

Zero-Voltage-Switching Voltage Doubled SEPIC Converter

2011
A zero-voltage-switching (ZVS) voltage doubled single-ended primary inductor converter (SEPIC) is presented in this paper. An active clamp circuit is added to the conventional isolated SEPIC converter to clamp the voltage across the switches and provide ZVS operation.

On the saturable inductor commutation for zero-voltage switching

21st Annual IEEE Conference on Power Electronics Specialists, 2002
A novel method of high frequency switching is presented, where a small saturable inductor is used for the zero-voltage switching. The saturated conditions of the inductor is satisfied by the use of a PWM (pulse width modulation) controller with a saturable core or by the use of a saturable transformer with current feedback. The switching losses and the

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 ...

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.

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,
