发明名称 Transformer and switching power supply unit
摘要 The transformer includes: a magnetic core having two base-plates and four legs; a first conductive member as a first winding, having four through-holes through which the four legs pass, respectively; and one or more second conductive members as a second winding, each having four through-holes through which the four legs pass, respectively. The first and second windings are wound around the four legs. Closed magnetic paths are formed inside the magnetic core from the four legs to the two base-plates due to currents flowing through the first or the second winding. A couple of magnetic fluxes each generated inside each of a couple of legs arranged along one diagonal line are both directed in a first direction, while another couple of magnetic fluxes each generated inside each of another couple of legs arranged along another diagonal line are both directed in a second direction opposite to the first direction.
