Flyback converter with hybrid clamp
2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018This paper presents a flyback converter with a hybrid clamp, i.e., a combined passive RCD and active clamp, and a corresponding power management circuit that substantially optimizes the performance of the flyback converter in the entire line and load ranges.

Performance evaluation of flyback converter
Proceedings Electrical Insulation Conference and Electrical Manufacturing Expo, 2005., 2006Steady-state (DC) analysis of the flyback PWM DC-to-DC converter is performed for continuous conduction mode (CCM). The equations for the device stresses and the component values are derived. The circuit is designed and simulated with the aid of P-SPICE.

30th Annual Conference of IEEE Industrial Electronics Society, 2004. IECON 2004, 2005
In this paper, a new sepic-flyback converter has been proposed, which is suitable for buck-boost topology. 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.

Actively clamped bidirectional flyback converter
IEEE Transactions on Industrial Electronics, 2000An actively clamped bidirectional flyback converter is proposed. The converter's operation is examined in detail. All switches in the converter have zero-voltage-switching characteristics. A low-frequency behavior model and small-signal transfer functions are derived. It is found that the flow of current is directly under the control of the duty cycle,

Non-Isolated Interleaved Flyback Converter
2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2018There is an ever-increasing demand for viable, clean, energy sources. The main obstacle in using solar energy sources is that the output voltage obtained is too low for practical use. The obtained output voltage should be stepped up considerably in connection with the utility mains.

Double-flyback DC-DC converter
Proceedings of PESC '95 - Power Electronics Specialist Conference, 2002Circuit operation is analyzed for the ideal and real circuit of a DC-DC power convertor. The voltage ratio is deduced for each operating mode as a function of load current, duty factor and component values. Boundary conditions between different operating modes are obtained. Component ratings are summarized, to facilitate circuit design. >

Active-clamping quad-flyback converter
2009 IEEE International Symposium on Industrial Electronics, 2009An 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.
