Abstract

A transformer includes a plurality of high-voltage side coils and a plurality of low-voltage side coils. The high-voltage side coils and the corresponding low-voltage side coils form a plurality of coil groups. A first coil group includes one of the high-voltage side coils and one of the low-voltage side coils wound around a first leg and one of the high-voltage side coils and one of the low-voltage side coils wound around a second leg adjacent to the first leg. A second coil group of the plurality of coil groups includes one of the high-voltage side coils and one of the low-voltage side coils wound around the first leg, and one of the high-voltage side coils and one of the low-voltage side coils wound around the second leg.
