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.

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,
