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. |
