An improved Flyback converter

2009 6th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2009
This paper presents a modified Flyback converter able to operate with higher efficiency and smaller size, overcoming most of the conventional flyback converter drawbacks, and also keeping its low cost and simplicity. In particular, the proposed converter allows the mosfet off voltage to be reduced and clamped to the input, thus recovering the ...

Design and implementation of flyback converters

2010 5th IEEE Conference on Industrial Electronics and Applications, 2010
In switch mode power supplies(SMPS), flyback converters are very popular because of, design simplicity, low cost, multiple isolated outputs, high output voltages and high efficiency. They are preferred especially for low power applications (150W).

Asymmetrical PWM flyback converter

2000 IEEE 31st Annual Power Electronics Specialists Conference. Conference Proceedings (Cat. No.00CH37018), 2002
The asymmetrical PWM converter with the flyback output rectifier (asymmetrical PWM flyback converter) is proposed in this paper. The asymmetrical PWM flyback converter has the feature of zero-voltage switching (ZVS) in the active switches using resonance of the parasitic components.

Resonant flyback converter

IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002
The paper discusses a new power converter circuit, the symmetrical resonant flyback power converter. Its fundamental mathematical analysis is presented, together with simulation results. The switches in the power converter operate with ZCS (zero current switching) at turn-on and with ZVS (zero voltage switching) at turn-off.

Ringing of Flyback Transformers

IEEE Transactions on Consumer Electronics, 1982
In this paper the third harmonic tuning of dissipative flyback transformers is discussed and conditions for minimum ringing and rules of variation of ringing voltage are investigated as the leakage inductance is tuned near minimum ringing.

Fuzzy based flyback converter

2014 International Conference on Advances in Electrical Engineering (ICAEE), 2014
DC-DC converters can be viewed as dc transformers that deliver a DC-DC voltage or current at a different level than the input source. The unregulated DC voltage is converted into regulated DC voltage at required level under varying load and input voltage condition.

Snubber Design for Flyback Converter

2021 25th International Conference Electronics, 2021
This article presents some design guidelines for the snubber of flyback converters. When the MOSFET turns off, a high-voltage spike occurs on the drain pin because of a resonance between the leakage inductor (LLK) of the main transformer and output capacitor (COSS) of the MOSFET. Therefore, it is necessary to add a circuit to clamp the voltage.

Hermetically Sealed Flyback Transformer

IEEE Transactions on Broadcast and Television Receivers, 1972
Conventional high voltage supplies for color TV occupy much space, with both rectifier and flyback transformer enclosed in a metal cage. The solid insulation materials used allow the possibility of smoke emission owing to a small production error as voltages of up to 30KV at 15.75 KHz are generated.

COMPLEXITY IN AN INDUSTRIAL FLYBACK CONVERTER

Journal of Circuits, Systems and Computers, 1995
In this letter a functional model of an industrial flyback converter is introduced. Its accuracy within a defined condition range is shown. The complexity of the system is discussed by using experimental data. Moreover, it is shown that the complex dynamics of a flyback converter can be clusterized in some classes of well-known paradigms appearing in ...

A novel AC-AC converter using bridgeless flyback rectifier and flyback CCM inverter

2016 Biennial International Conference on Power and Energy Systems: Towards Sustainable Energy (PESTSE), 2016
The performance analysis of an AC-AC converter which is the combination of flyback rectifier with a bridgeless configuration and flyback inverter in a continuous conduction mode is discussed here. Compared to the basic bridge diode topology, the flyback rectifier with a bridgeless configuration can solve the problems related to conduction losses ...
