Fuzzy FDI System for Flyback Converters
IEEE Transactions on Fuzzy Systems, 2021In this article, the design of a fault detection and isolation (FDI) system for a flyback converter, based on a fuzzy unknown input observer, is presented. The proposed FDI system aims to detect the saturation in the inductor core as a fault, considering the current increment can cause an avalanche effect provoking a failure in the system.

Design and implementation of flyback converters
2010 5th IEEE Conference on Industrial Electronics and Applications, 2010In 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).

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 ...

Ringing of Flyback Transformers
IEEE Transactions on Consumer Electronics, 1982In 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.

A Flyback Rectifier With Spread Harmonic Spectrum
IEEE Transactions on Industrial Electronics, 2011This paper presents a flyback switch-mode rectifier (SMR) with spread harmonic spectrum. The SMR switching control is conducted by a charge-regulated pulsewidth modulation (PWM) scheme with constant turn-on period. The inherently stable discontinuous conduction mode operation is preserved to yield good line drawn power quality.

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,

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.

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.
