PURPOSE:To provide a controller which can supply power efficiently by enabling one end of the load to be grounded for a load such as an induction motor, driven at low voltage equivalent to the battery on an automobile. CONSTITUTION:A controller, which supplies a current to the load operating at AC low-voltage, is composed of a battery 2, which supplies DC voltage, a polarity inverting circuit 3, which generates voltage -E of inverted polarity, an AC voltage composer 6, which forms AC voltage by switching voltages E and -E over to each other, and a controller 7, which generates AC voltage from the AC voltage composer 6 by switching the voltages E and -E over to each other. |
