Abstract

PURPOSE:To obtain a stable operation of a synchronous motor by detecting the voltage of an AC power source when the voltage of the power source decreases and decreasing the DC voltage of a converter during the operation of an inverter for deciding the DC voltage of the converter for driving a synchronous motor. CONSTITUTION:A signal detected by a converter 12 from the voltage of an AC power source 1 is inputted to a DC voltage alternation signal generator 31, and when the voltage value decreased to the AC input rated voltage value or lower, the signal generator 31 generates a signal. A signal determined by a margin angle setter and the output signal of the generator 31 are added by an adder 32, and the added signal is inputted to a margin angle controller 25. Thus, the controller 25. thus, the controller 25 operates to increase the margin angle of a converter 6 and decreases the DC voltage Ed.
