The Design of the Secondary Electrical Circuit of a Flyback Transformer with Hybrid Magnetic Core

We present numerical modeling results for a planar, miniature flyback transformer (FBT) powered by a pulse with modulated (PWM) voltage supply, whose magnetic core is hybrid, made of ferrite, magnetic nanofluid and non–magnetic parts. The central column, made of the ferrite, has an air gap for enhanced energetic performance. This paper is concerned with the analysis of the electrical secondary (load) circuit with the aim to adapt it to optimally transfer the energy stored within the transformer and to minimize the losses during the switching time.
