Abstract:
1. A voltage transforming apparatus to be mounted in a vehicle, said voltage transforming apparatus comprising: a primary winding receiving an AC voltage; a plurality of secondary windings that are different in number of turns; and a voltage conversion circuit for converting an AC voltage induced in each of said plurality of secondary windings into a desirable voltage, each of said plurality of secondary windings including a first terminal and a second terminal each having a potential that is not fixed, and said first terminal and said second terminal being separately provided in each of said secondary windings, said voltage transforming apparatus further comprising: a switching circuit for selectively connecting said first terminal and said second terminal of each of said plurality of secondary windings to said voltage conversion circuit, said vehicle running through a plurality of sections of a path of travel in which AC voltages are different, said voltage transforming apparatus further comprising an iron core, said iron core including said plurality of secondary windings including first and second secondary windings, and said first and second secondary windings being wound around said main leg so as to sandwich said primary winding.
