Abstract:
1. An inverter transformer comprising: a magnetic core assembly comprising a plurality of legs; a plurality of bobbins each having a primary winding and a secondary winding wound therearound, and each having one of the plurality of legs inserted therein, wherein two sets of adjacent two bobbins of the plurality of bobbins constitute a first bobbin pair which is provided with respective secondary windings at which output voltages having their polarities reversed from each other are induced, and a second bobbin pair which is provided with respective secondary winding at which output voltages having an identical polarity are induced; and an insulation distance setting means provided between the two bobbins of the first bobbin pair so that a distance between the secondary windings disposed at each of the two bobbins of the first bobbin pair is larger than a distance between the secondary windings disposed at each of the two bobbins of the second bobbin pair.
