专利汇可以提供Device for feeding current to linear motor专利检索,专利查询,专利分析的服务。并且PURPOSE:To control the reactive power of an AC input power supply to a linear motor by providing a reactive power controller for compensating the variation of the reactive power occurred when current is supplied to a propulsive coil of the motor while sequentially changing over switches. CONSTITUTION:The propulsive coil of a linear motor is divided into propulsive coil units LM1-LM4 in its respective sections, which are sequentially alternatively conmected via awitches SW1-SW4 to feeders F1, F2. Power converters CC1, CC2 are connected to the respective feeders, and first and second reactive power controllers RPC1, RPC2 are connected between the primary winding of a transformer Tr and an AC power supply SS. When a train TRAIN is located over two feeder sections, both the power converters CC1 and CC2 simultaneously operate to cause the primary winding apparent power of the transformer Tr to alter according to the reactive power. Accordingly, the basic reactive power is compensated by the first reactive power controller RPC1, and the other reactive power is compensated by the second reactive power controller.,下面是Device for feeding current to linear motor专利的具体信息内容。
