发明名称 FRACTIONAL TURNS TRANSFORMER WITH FERRITE POLYMER CORE
摘要 Conventional transformers with fractional turns have pre-manufactured cores usually with a complicated structure. According to the present invention, a method is provided of manufacturing a planar transformer where a ferrite polymer compound is laminated to a PCB for forming the core of the transformer. Advantageously, this may allow for the provision of a cheap and robust transformer.
