Abstract:
1. A transformer comprising: a magnetic core including two base-plates facing each other and four legs provided between the two base-plates to couple the two base-plates together, the four legs being arranged along a pair of diagonal lines intersecting each other in a plane along facing surfaces of the two base-plates; a first conductive member having four through-holes through which the four legs pass respectively, and configuring a first winding which is wound around the legs; and one or more second conductive members each having four through-holes through which the four legs pass, respectively, and each configuring a second winding which is wound around the four legs, wherein the first and second windings are wound around so that closed magnetic paths are formed inside the magnetic core from the four legs to the two base-plates due to currents which flow through the first or the second winding, and so that a couple of magnetic fluxes each generated inside each of a couple of legs arranged along one of the two diagonal lines are both directed in a first direction, while so that 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 which is opposite to the first direction.
