TWELVE-PHASE TRANSFORMER-COUPLED PHASE CONVERTER |
摘要 |
FIELD: electricity.SUBSTANCE: invention is related to converter equipment and may be used for manufacturing of rectifiers for direct and alternating-current electric controlled drives in order to improve their operational speed. Twelve-phase transformer-coupled phase converter consists of a three-phase converter having three wye- (or delta-) connected coils of the primary winding coupled to the three-phase network with zero wire, six interconnected coils of the secondary windings with taps from turns. Each coil of the secondary winding of the transformer is a side of the hexagon circuit that converts a symmetric three-phase system of voltage into six-phase system of voltage. Each tap of the secondary winding coil turn is one of outputs of the symmetric twelve-phase voltage system of the converter. Voltage of the twelve-phase voltage system depends on a voltage value of the six-phase system and is related to it as per the following ratio: U=UCos30°/Cos15°=0.897U.EFFECT: reduction of converter dimensions and weight, simplification of its design and manufacturing technology and reduction of its cost.2 dwg |
