Abstract

PURPOSE:To inhibit the hunting of a motor by feeding back a value corresponding to variation in the input (output) current of an inverter to a voltage frequency converter determining the output frequency of the inverter. CONSTITUTION:The output of a pulse width modulated voltage type inverter device 14 is applied to an induction motor 6 through a current transformer 5. A command frequency reference from a frequency setting device 7 and the output voltage of the inverter 14 are applied to a voltage control circuit 10 to form a voltage control signal which is inputted into a pulse modulation control circuit 11. A load current detection signal from a current transformer 5 is applied to an arithmetic circuit 13 with an inverter input current detection signal, the command frequency reference by way of a phase inverter 12 and formed as frequency control signal with a voltage frequency converter 15 and applied to a pulse width modulation control circuit.
