Abstract

Disclosed is a power saver that achieves maximum efficiency by applying a step-down transformer mechanism to a highly efficient toroidal core that has been subjected to heat treatment several times or more. The power saver uses a toroidal core in which primary and secondary coils (L1 and L2) (11 and 12) are wound on the toroidal core so that they overlap each other with almost the same winding angle coverage. If such a power saver is installed at each load, it can provide high quality power and maximize power saving efficiency.
