Title:
VOLTAGE TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2011/068044
Kind Code:
A1
Abstract:
A voltage transformer comprises: a primary winding (3) that receives an AC voltage; a plurality of secondary windings (4a, 4b) that have mutually different numbers of turns; and a voltage converter circuit (5) for converting AC voltages induced in the plurality of secondary windings (4a, 4b). The plurality of secondary windings (4a, 4b) each have first and second terminals at which the potentials are not fixed. The first and second terminals are provided individually for each of the secondary windings (4a, 4b). The voltage transformer further comprises a switching circuit (8) for selectively connecting the first and second terminals of either one of the plurality of secondary windings (4a, 4b) to the voltage converter circuit (5).
