<p>PURPOSE:To reduce magnetic flux leakage by a method wherein a winding is divided and wound around one leg and the other leg of a magnetic core, each of the windings connected in series to form a first winding, and a second winding is formed by similarly dividing, winding and connecting in series, then the first and the second windings are connected in parallel, thereby forming an input winding. CONSTITUTION:A pair of U-shaped or UI-shaped magnetic cores are abut with each other in the state where a gap spacer 8 is interposed, and an almost square-shaped magnetic path is formed, thereby constituting a magnetic core 2; a winding is divided, and wound around one leg 2a and other leg 2b of the core 2; each of the windings 3a, 3b are connected in series, thereby forming a first winding 3. In the similar manner, a winding different from the first winding 3 is divided and wound around the one leg 2a and the other leg 2b of the magnetic core 2; each of the windings 4a, 4b are connected in series, thereby forming a second winding 4. The first winding 3 and the second winding 4 are connected in parallel, thereby forming an input winding. Thus magnetic flux leakage is reduced. For example, a secondary winding 5 and a third winding 6 are closely wound so as to correspond with the above primary windings 3a, 4a.</p> |
