Abstract

PURPOSE:To reduce losses by dividing first and second windings into a plurality of parts, connecting them in parallel at the time of a full load, and in series at the time of a light load. CONSTITUTION:At the time of the full load,the first windings 2 and 3 and the secondary windings 5 and 6 are connected in parallel by switches 4 and 7. A voltage determined by the turn ratio of the primary windings 2 and 3 and the secondary windings 5 and 6 is supplied to the load connected to the secondary windings 5 and 6. Under this state, the primary current the secondary current are large. But since the primary windings 2 and 3 and the secondary windings 5 and 6 are connected in parallel, the load loss is small. At the time of the light load, the primary windings 2 and 3 and the secondary windings 5 and 6 are connected in series by the switches 4 and 7. Under this state, the magnetic flux density through a core 1 is lowered, and no-load loss is reduced.
