Title:
TRANSFORMER DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/179475
Kind Code:
A1
Abstract:
A transformer device, provided with: a primary coil (3), which receives an AV voltage; and a plurality of secondary coils (4a, 4b) having different numbers of windings, each of the secondary coils (4a, 4b) separately having first terminals (9a, 9c) and second terminals (9b, 9d) having potentials that are not fixed. The transformer device is also provided with: voltage conversion circuits (5, 6) for converting an AC voltage induced in the secondary coils (4a, 4b) to a desired voltage; and a switching circuit (8) for selectively connecting the first terminals (9a, 9c) and the second terminals (9b, 9d) of each of the secondary coils (4a, 4b) to the voltage conversion circuits (5, 6). In one of the secondary coils amongst the plurality of secondary coils (4a, 4b), a plurality of conductors (41, 42) are concentrically wound in a state of being insulated from each other, and the winding-start end (42a) and the winding-finish end (41b) of adjacent conductors (41, 42) are connected to each other so that the conductors (41, 42) are serially linked.
