CONVERTER OF THE THREE-PHASE ALTERNATING CURRENT INTO THE ALTERNATING ONE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: converter has phase and line bridge rectifiers connected with the phase windings of the engine stator. Thyristor are switched on to the same windows. The duplication of the synchronous frequency is exercised in the engine. If the necessity of its drop arises, each of the thyristors is in an open state during several half periods of the rectified voltage. The converter is used in electrical networks and in the engines of the alternating current. EFFECT: facilitated manufacture. 2 dwg
