Our compact switching converter using a thin-film microtransformer mono-lithically integrated with rectifier diodes represents the first step in developing a monolithic micro-switching converter that can be integrated with semiconductor devices and magnetic components. This converter is a single-ended forward converter with resonant reset and operates successfully at 15 MHz. The maximum output power is 0.5 W.

This letter describes an analysis of a series resonant converter in which the effects of the output transformer's magnetizing inductance on the converter's output characteristics are considered. It is clarified that the output power decreases when the magnetizing inductance has a low value.
