A simulation of conducted EMI in flyback converters
Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012The measure of conducted EMI needs strict environment and expensive instruments, most of the designers don't have this condition. So, there are demands for economic forecast of conducted EMI before the product being tested by the government. This paper tries a simulation method to forecast the conducted EMI of a flyback converter.

Circuital and mathematical modelling of flyback converters
2016 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2016A circuital and mathematical modelling of flyback converters is presented in this paper. It accounts for many parasitic elements of each flyback devices, among which transformer leakage inductances and junction capacitances of semiconductor devices. An equivalent circuital representation of the flyback converter is introduced at first, based on which a

A dual mode forward/flyback converter
1982 IEEE Power Electronics Specialists conference, 1982This paper presents a single transistor dc-dc converter that combines both forward and flyback action. The resulting circuit is ohmically isolated and can operate over a wide range of input-to-output voltage ratios. An analysis of the circuit indicates that the forward and flyback portions of the circuit interact to produce three distinct regions of ...

Conference Proceedings., Eleventh International Telecommunications Energy Conference, 2003
It is demonstrated that it is possible to manufacture a very compact high-power switch-mode power supply based on the flyback technique using standard components, with no sacrifice in performance and operation at 80 kHz. A superior flyback converter can be designed on the basis of the following criteria: (1) choosing a pulse ratio to optimize the ...

The Active Clamp Sepic- Flyback Converter
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006A high efficiency active clamp sepic-flyback converter is presented. The proposed converter is superposition of sepic converter mode and flyback converter mode. Not only sepic mode output but also flyback mode output can be fully regulated by constant frequency PWM control. Merging sepic and flyback topology can share the transformer, power MOSFET, and
