Waveform dependent switching losses in flyback transformer foil windings

2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003
The copper losses in a foil wound flyback transformer are examined using a time domain 2-D finite element model. The purpose of the study is to examine the losses as a function of switching waveform. It is shown that the windings carry nonnegligible induced current at times when the net current in the winding is zero.

An improved winding loss analytical model of Flyback transformer

2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010
The winding loss of Flyback transformer is difficult to calculate because the current flowing in both sides is not simultaneous, and the current phase shift at each harmonic between primary side and secondary side is not fixed at 180o. This paper proposes a novel winding loss analysis model by considering the phase shift angle of the two current and ...

Development of a Corona Discharge Detector for Flyback Transformers

IEEE Transactions on Consumer Electronics, 1977
This paper describes a new corona discharge detector for flyback transformers. It can detect corona discharges which are generated by the flyback pulse and have a great effect on the reliability of flyback transformers. It also adds greatly to the insulation design and quality control of flyback transformers.

An active-clamping ZVS flyback converter with integrated transformer

2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014
This paper propose an active-clamping flyback converter using a integrated transformer. The proposed converter is composed of two active-clamp flyback converter. The presented converter can equally share the total load current between two secondaries so that the rectifier diode conduction loss can be decreased.

Design and prototype of flyback transformer driven electro hydrodynamic thruster

2016 7th India International Conference on Power Electronics (IICPE), 2016
An Electro-hydrodynamic (EHD) thruster is a static device that employs electro-hydrodynamic phenomenon to produce thrust in the air. It generates net vertical force from electrostatic field. It consists of two parallel conducting electrodes, one in the form of a fine wire and the other in the form of a foil skirt.
