| 摘要 |
The invention relates to a three phase voltage control system for connection to a three phase power supply line. The system comprises first, second and third autotransformer devices (AT1, AT2, AT3) and first, second and third magnetic controllable inductor devices (M1, M2, M3). The magnetic controllable inductor devices (M1, M2, M3) each comprises a primary winding, a secondary winding and a control winding. The first primary terminal (M1p1) of the first magnetic controllable inductor device (M1) is connected to first secondary terminal (M3s1) of the third magnetic controllable inductor device (M3), the first primary terminal (M2p1) of the second magnetic controllable inductor device (M2) is connected to first secondary terminal (M1s1) of the first magnetic controllable inductor device (M1), the first primary terminal (M3p1) of the third magnetic controllable inductor device (M3) is connected to first secondary terminal (M2s1) of the second magnetic controllable inductor device (M2), he second secondary terminal (M1s2) of the first magnetic controllable inductor device (M1) is connected to the second parallel terminal (AT2p2) of the second autotransformer (AT2), the second secondary terminal (M2s2) of the second magnetic controllable inductor device (M2) is connected to the second parallel terminal (AT3p2) of the third autotransformer (AT3) and the second secondary terminal (M3s2) of the third magnetic controllable inductor device (M3) is connected to the second parallel terminal (AT1p2) of the first autotransformer (AT1). |
