Abstract

PURPOSE:To prevent and change of tertiary voltage according to the position of a tap by winding one side of two exciting winding, to which constant voltage is applied and which is connected in series, and tertiary winding on the same core. CONSTITUTION:The tertiary winding 30 and the exciting winding 50 are wound on a main leg 72, and the exciting winding 52 connected in parallel with the winding 30, tap winding 4 and the exciting winding 51 connected in series with the winding 50 are wound on a side leg 70. The excitation of the core leg on which the winding 50 is wound does not change according to the position of the tap because voltage between both terminals u, v of the winding 50 is constant. Accordingly, the voltage of the winding 30 is also constatnt regardless of the position of the tap. Since the induced voltage of the tap winding is constant, stepping voltage is also constant, the width of the voltage changes at the plus side and the minus side is also equalized, and the transformer is easily controlled.
