Abstract :
In order to realize small power supplies, the authors propose a type of coreless high-frequency transformer. This transformer is composed of simple twisted coils and its operating principle is based on the skin effect of current carrying conductors. Approximate analysis based on the symmetrical current distributions in each of the coil axes has been applied to this transformer. As a result, it has been clarified that the simple analytical model can be used to estimate the rough performance of the transformer. Analytical and experimental studies suggest that twisted coils have versatile possibilities as a high-frequency transformer
