Active-clamping quad-flyback converter

2009 IEEE International Symposium on Industrial Electronics, 2009
An active-clamping quad-flyback converter is proposed to achieve zero voltage switching (ZVS) for all power switches. The secondary sides of quad-flyback converter are connected in parallel to share the load current. Thus, the transformer copper losses and the conduction losses on the output diodes are reduced.

Analysis of an Active Clamp Forward Converter

2005 International Conference on Power Electronics and Drives Systems, 2006
This paper studies the detailed circuit operation, mathematical analysis and design example of the active clamp forward converter with synchronous rectifier. There is one auxiliary switch and one clamp capacitor used in the forward converter to recycle the energy stored in the transformer leakage in order to minimize the spike voltage at the ...

The Active Clamp Sepic- Flyback Converter

IEEE 36th Conference on Power Electronics Specialists, 2005., 2006
A 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

1 kW PFC converter with compound active-clamping

IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2004
A PFC converter employing compound active clamping technique is proposed. It can effectively reduce the loss caused by diode reverse recovery. Both the main switch and the auxiliary switch can achieve soft-switching (ZVS) under certain conditions. The parasitic oscillation caused by the parasitic capacitance of the boost diode is eliminated.

A voltage equalizer using flyback converter with active clamp

2012 IEEE Asia Pacific Conference on Circuits and Systems, 2012
This paper proposes a voltage equalizer using flyback converter with active clamp. This novel voltage equalizer is able to reduce the power losses. An active clamp circuit is used as an auxiliary circuit to achieve zero voltage switching (ZVS). Simulation results with PSIM and experimental results are shown. The proposed circuit is confirmed to be more

Fault-tolerance capacity of the multilevel active clamped topology

2011 IEEE Energy Conversion Congress and Exposition, 2011
Thanks to the inherent redundancy to generate the different output voltage levels, the multilevel active clamped (MAC) topology presents an important fault-tolerance ability which makes it interesting for several applications. This paper presents an analysis of the fault-tolerance capacity of the MAC converter.
