Analysis of bidirectional flyback converter
2015 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC), 2015Power 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 Modified Asymmetrical Half-Bridge Flyback Converter for Step-Down AC–DC Applications
IEEE transactions on power electronics, 2020This article presents a modified asymmetrical half-bridge flyback converter (AHBFC) to fulfill the single-stage step-down ac–dc universal input voltage application. This topology is obtained from the integration of a buck-type power factor correction, an

A Constant Current Digital Control Method for Primary-Side Regulation Active-Clamp Flyback Converter
European Conference on Cognitive Ergonomics, 2020Active-clamp flyback converter is now widely used because higher efficiency is obtained with soft-switching technique. However, opto-coupler is always applied in the feedback loop to acquire the output signal.

A Digital Control Scheme for PSR Flyback Converter in CCM and DCM
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020Due to the simple structure and low cost, the primary-side-regulation (PSR) flyback converter is widely used in small power applications. As the output voltage is sampled from auxiliary winding in PSR flyback converter, some sampling error exists ...

A ZCS bidirectional flyback converter
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004This 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, 2013This 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., 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
