Abstract
PURPOSE: To enable to reduce the number of power-supply lines by connecting the neutral terminal of a star-connected synchronous motor to the center terminal of DC power supply, and supplying power to the synchronous motor from first and second inverters connected to the positive and negative terminals OF the dc power supply.
CONSTITUTION: The neutral terminal of a star-connected synchronous motor 20 is connected to the center terminal C between the terminals P and N of a DC power supply, and power is supplied to the synchronous motor 20 from a 3-phase first inverter 13 and single-phase second inverters 14∼16 which are connected to the positive and negative terminals P and N of the DC power supply. The outputs from the second inverters 14∼16 are arranged with the outputs of individual phases of the first inverter 3 in series through transformers 17∼19, respectively. When the syncrhonous motor 20 is started from a stationary state or it is oerated at a low speed, only the first inverter 13 is operated. In this constitution, only 4 power-supply lines can be used instead of 6 power-supply lines in the conventional constitution. In the case of a linear synchronous motor and the like which requires especially long power supply lines, the circuit can be constituted simply. Therefore, economization of wire material is greatly improved.
