A Transformer with Adjustable Leakage Inductance

摘要

The leakage inductance of the transformer employed in a series resonant converter can be used for resonance to make the device more compact. The value of this inductance should be controllable and sufficient large. In this paper the novel structure of a transformer with adjustable leakage inductance is proposed and the design methodology is presented so as to reduce the size of power resonant converters.
