Abstract

Flyback topology is considered as the lowest part count topology in Switched Mode Power Supplies (SMPS) family with isolated output capability. Without needing any output inductor the critical magnetic part to be considered within the circuit was only flyback transformer. Benefiting the recent advancement of a technology which used in constructing integrated circuits the reproducibility quality of the transformer could be guaranteed. Thus the new flyback topology with split-planar transformer style was introduced. Topology circuit simulation has been conducted and discussed within the model parameters of 5 W capacity, 500 to 1.5 MHz operation, 15 V output voltage with 80% efficiency, taking input from a single photovoltaic module. The most suitable pairs of power transformer to be micro fabricated on a silicon wafer found to be 6 pairs with the core gap of 100 um at 1 MHz operation frequency.
