PURPOSE:To simplify the structure and to improve the efficiency by disposing to flow a current to an armature winding through a rectifier in parallel from an external terminal via the secondary winding by a current transformer and a reactive element. CONSTITUTION:A rotary electric machine has a current transformer 2 in which the primary winding 1 is connected with the external terminals 4-6 of an armature winding 3 and external wirings 7-9, and reactive elements 15-18 connected with the terminals 4-6 are connected in parallel with reactors 22-24. The phase intermediate terminals 25-30 of the winding 3 are respectively connected with the rectifiers 22-24, and the DC exciting winding 35 of a saturable reactor 37 is controlled by an automatic voltage regulator 36. Thus, currents are flowed from the secondary windings 10-12 and external terminals 4-6 in parallel to the winding 3 to improve the efficiency by simplifying the structure. |
