Abstract

With ever-increasing demands of smaller size, lighter weight for all forms of AC-DC consumer electronics, and wire winding transformers have been most used in isolated adaptor for over a century. The most popular isolated AC-DC adaptor topology is the flyback, but the leakage inductance and switching losses of a traditional flyback limit the switching frequency and prevent the ability to achieve a small solution size. This paper demonstrates new ways to optimize flyback topology with planar PCB-embedded transformer to produce much higher efficiencies, even while switching at a higher frequency for adapter application.
