Abstract

Saturation is avoided in the core of the transformer used for direct conversion in a single-ended dc-to-dc converter of the type using auxiliary flyback conversion through a plural-winding inductor. This is done by resetting the core with a winding threading the core, through which winding the secondary current of the plural-winding inductor passes.
