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 bidirectional flyback converter

2015 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC), 2015
Power converters have great importance in this technically advanced world because many electronic devices use controlled source. Thus new converting topologies are developing to get better operation in terms of efficiency. This paper deals with a bridgeless flyback converter topology which have bidirectional power flow capability.

A ZCS bidirectional flyback converter

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
This paper addresses the design and analysis of a zero-current-switched (ZCS) bi-directional flyback dc/dc converter. The converter is based on extending a previously developed unidirectional ZCS flyback converter and replacing the output diode with a controlled switch, which acts as either a rectifier or a power control switch in the corresponding ...

A DC-DC converter with stacked flyback converters

2013 IEEE Energy Conversion Congress and Exposition, 2013
This paper proposes a new two-switch flyback converter that allows its switches to operate with less peak voltage stress than other flyback converters and with double their power transfer frequency. Moreover, the converter can operate with zero-voltage switching (ZVS) using just one auxiliary switch.

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

Buck-flyback DC-DC converter

IEEE Transactions on Aerospace and Electronic Systems, 1988
It is difficult to obtain a large input/output voltage ratio with a DC-DC converter, because the duty factor d may not reach very small values. For the same reason, it is difficult to obtain an output voltage that is adjustable in a large range. A DC-DC converter circuit is proposed that overcomes this limitation by performing a voltage ratio d/sup 2//(

Radio frequency dc-dc flyback converter

Proceedings of the 43rd IEEE Midwest Symposium on Circuits and Systems (Cat.No.CH37144), 2002
An RF (radio frequency) dc-dc converter has been developed to demonstrate the possibility of using a flyback configuration at 63 MHz. The converter consists of two sections: a variable pulse width generator (PWG) and a FET switch with a transformer and a detector.
