Abstract

PURPOSE:To prevent common mode noises and normal mode noises, by utilizing an iron core, wherein high frequency effective permeability is low and the primary winding and the secondary winding are not overlapped, and providing electromagnetic shields around the windings. CONSTITUTION:The primary winding 1 and the secondary winding 2 are not overlapped but separately provided. The iron core 6, wherein the high frequency effective permeability is low is arranged so that it is pierced through and coupled with both windings. Around said primary winding 1 and the secondary winding 2, are provided the electromagnetic shielding plates 3 and 4 comprising copper, aluminum, and the like, respectively. A shielding plate 5 is provided between the primary winding 1 and the secondary winding 2 through the center of the core if required. In this constitution the normal noises are prevented, and, as a result, the common mode noises can be prevented more perfectly.
