Active-clamping ZVS flyback converter employing two transformers

2007 International Aegean Conference on Electrical Machines and Power Electronics, 2007
This paper presents a two-transformer active- clamping zero-voltage-switching (ZVS) flyback converter, which is mainly composed of two active-clamping flyback converters. [1]-[2] By utilizing two separate transformers[3], the proposed converter allows a low-profile design to be readily implemented while retaining the merits of a conventional single ...

Novel winding loss analytical model of flyback transformer

2006 37th IEEE Power Electronics Specialists Conference, 2006
A novel winding loss model of Flyback transformer for loss calculation is proposed. With this model, the winding losses can be divided into transformer loss and inductor loss by decomposing the total winding currents into two components, that is, transformer current, or T-component and inductor current, or L-component, which are orthogonal in continued
