Abstract

PURPOSE:To suppress the transient increment of a momentary peak value of motor current, by regulating a modulation degree and slip frequency, according to the increment component of the transient change of the input voltage of an inverter due to the fluctuation of stringing voltage. CONSTITUTION:By a modulation degree arithmetic circuit 10, arithmetic is performed on a modulation degree according to the input voltage Ec of an inverter 4. In the meantime, from a modulation degree reducing means 15 and a slip frequency reducing means 17, according to the change component of the inverter input voltage Ec, the output of reducing signal is generated. Then, based on the output of the modulation degree arithmetic circuit 10 and the modulation degree reducing means 15, arithmetic is performed on the modulation degree, and based on the output of a slip frequency controlling circuit and the slip frequency reducing means 17 and rotational frequency fn, arithmetic is performed on inverter frequency. From a modulation means 7, the output of the control signal of the inverter 4 is generated according to the inverter frequency and inverter input voltage Ec.
