Abstract
A voltage transforming apparatus includes 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 the plurality of secondary windings. Each of the plurality of secondary windings includes the first terminal and the second terminal each having a potential that is not fixed. The first terminal and the second terminal are separately provided in each of the secondary windings. The voltage transforming apparatus further includes a switching circuit for selectively connecting the first terminal and the second terminal of each of the plurality of secondary windings to the voltage conversion circuit.
