Abstract

PURPOSE:To obtain optional output voltage by severally forming each primary, secondary, tertiary and quartic winding of the transformer in the star connection, the delta connection, the autotransformer and each phase coil. CONSTITUTION:The primary winding S1, S2, S3 of the transformer is formed in the star connection, secondary winding D1, D3, D5 and D2, D4, D6 in the delta connection, the tertiary winding A1, A2, A3 and A4, A5, A6 in the autotransformers and the quartic winding B1, B2, B3 and B4, B5, B6 in each phase coil connection. Accordingly, power required can be outputted by varying the ratio of transformer between the tertiary winding and the quartic winding.
