Abstract
PURPOSE: To provide the subject device wherein a voltage control loop due to the DC voltage of a power inverter control circuit, thereby to suppress the rise of a commutation capacitor voltage upon drawing the induction motor to the driving region of the current type inverter.
CONSTITUTION: The device comprises a detector 621 for detecting a DC voltage of a power inverter 40, and a voltage pattern changing circuit 623 for changing the output signal generated from the voltage pattern generating circuit 6 of the current inverter in accordance with the detected signals from the detector and imparting the output signal to a voltage controller 614. The above described changing circuit comprises a circuit 623a for squaring the detected signals of the detector 621, a setting circuit 623b for setting a desired voltage suppressive level, an adding circuit for adding the outputs of both circuits, a square root circuit 623c for computing the square root of the added value of said adding circuit, and a voltage pattern suppression circuit 612 for comparing the output of said circuit with the output of the voltage pattern generating circuit, and introducing the smaller obtained value to the voltage controller
