Abstract: A leakage transformer includes a core and a printed wiring board. The core includes a first magnetic leg and a second magnetic leg. The second magnetic leg is spaced from the first magnetic leg. The printed wiring board includes an insulating portion and conductor wiring. The conductor wiring includes a first coil and a second coil. The first coil is formed of a first winding and is wound around only the first magnetic leg, not around the second magnetic leg. The second coil is formed of a second winding and includes a first part and a second part. The first part is wound around only the first magnetic leg, not around the second magnetic leg. The second part is wound around both the first and second magnetic legs.

Abstract: A reactor includes a plurality of windings, a coupling core, and an inductor core. A coupling core configured to form a coupling closed magnetic circuit that magnetically couples the plurality of windings, the plurality of windings being wound around the coupling core; and. An inductor core, which includes a main part, a first projection part projecting from one end of the main part, and a second projection part projecting from another end of the main part, and each of the first projection part and the second projection part is magnetically connected to the coupling core. The inductor core forms an inductor closed magnetic circuit together with a part of the coupling core around which one winding of the plurality of windings is wound.
