<p>PURPOSE:To abate the electromagnetic force produced between group windings and power supply windings by a method wherein the winding arrangement is to be made so that the axial directional centers of ampere turn distribution of respective power supply windings and group windings in mutually concentric arrangement relation may be made coincide with one another in the axial direction. CONSTITUTION:Within the title three phase transformer cycloconverter, iron cores 20 having three legs 20U-20W, the first-fourth group windings 3U, 4U, 6U, 7U in respective regions divided into four quarters in the axial direction thereof are arranged in respective legs of the iron cores 20. Next, respective outer peripheries of the group windings are wound up with power supply windings comprising four each of split windings 2Ua-2Ud so that the concentric arrangement making the axial direction centers coincide with one another may be made. Finally, both of the first and second winding parts are wound up with the fifth group winding 5U likewise both of the third and fourth winding parts are wound up with the six group wiring 8U so that the concentric arrangement may made.</p> |
