Abstract
PURPOSE:To ensure starting of an apparatus by supplying a power for a control circuit at the time of starting an inverter from an auxiliary power operated by the stored energy of a capaci tor from a high-voltage DC power via a voltage dividing resistor. CONSTITUTION:A power converter (inverter) 1 is composed of a main circuit 1A connected with a pantograph 3, a transformer 1B, a full-wave rectifier circuit 1C, a filter circuit 1D, and a control circuit 4; and is further equipped with a starting circuit SC and others. In this case, said power converter is provided with a voltage dividing and charging means DC, which includes first and second resistors 8 and 9 and a capacitor 10 connected in series with each other between a high-voltage DC power 2 and ground via said pantograph 3, to voltage-divide and charge said capacitor 10. Further, the input side of an auxiliary power 11 is connected with both ends of the capacitor 10 and its output side is connected with the control circuit 4 to supply electricity. Moreover, the make and break means of an input circuit for the auxiliary power 11 is composed of the B contact BR of an output voltage detection relay 14 for the in verter 1.
