FIELD: electricity. ^ SUBSTANCE: invention is related to the sphere of electric equipment, may be used in electric drive system. Technical result is increase of efficiency factor and operation reliability, design and production technology simplification. Valve machine of alternating current contains rotor, stator with three phase working winding, connected in star, three control windings, the inputs of which are connected to the output of bridge autonomous inverter, and their outputs - to outputs of secondary windings of booster transformer. Inputs of three phase working winding are connected to the output of bridge autonomous inverter, and its outputs form neutral star point and are connected to the input of primary winding of booster transformer. The use of specified winding connection circuit results in the fact that magnet system of each phase enters saturation mode only for a short period of time. ^ EFFECT: increases efficiency factor and reliability of alternating current valve machine operation with simplification of its design. ^ 6 dwg |
