TRANSFORMER HAVING A FUNCTION OF COMMON-MODE NOISE REJECTION

摘要

PURPOSE: A transformer including a noise filter function is provided to reduce production costs and time of a user system by mutually using a magnetic core. CONSTITUTION: A transformer core(4) includes a first side and a second side facing the first side. A forward filter coil(5) is wound on one of the first side or the second side in a first direction. A power deliver coil(6) is wound on the same side of the forward filter coil in the same direction of the first direction by being connected to the forward filter coil. The power deliver coil and the forward filter coil are distinguished by a first tab(1). A reverse filter coil(7) is connected to the power deliver coil in a second direction.
