MAGNETIC ENERGY TRANSFER DEVICE AND A POWER SUPPLY UNIT CAPABLE OF OFFSETING ELECTRICAL NOISE AND REDUCING UNIT COST OF A TRANSFORMER

摘要

PURPOSE: A magnetic energy transfer device and a power supply unit are provided to minimize deviation of electro-magnetic interference in the mass production by eliminating conducted noise and radiant noise.;CONSTITUTION: An input wire(191a) is rolled on a core of a magnetic energy transfer device. The input wire controls the flow of a current and transmission of magnetic energy by the switching operation of a switching element. An output wire(193) is magnetically combined with the input wire and supplies the magnetic energy to load. An offsetting wire(192a) locates between the input wire and the output wire. The offsetting wire shields capacitive combination through distributed capacity of opposite side of the input wire and the output wire.;COPYRIGHT KIPO 2012
