Abstract:
A power supply system, provided with a high voltage system and a low voltage system, comprising:an a.c. motor that is a load on the high voltage system and is driven by a high voltage power source; an inverter for controlling supply of power to the a.c. motor; a low voltage system supply path for applying a neutral point voltage of the a.c. motor to a load of the low voltage system; and a load of the low voltage system for connecting to the low voltage system supply path, wherein: a voltage ratio of the low voltage system to the high voltage system is set to from 1:2 to 1:4; and the inverter is controlled so that an a.c. component in output from the inverter is not sinusoidal in shape, but follows a current distortion phenomena.
