Abstract

PURPOSE:To stabilize the voltage controlling operation state of an inverter device by clamping a voltage command lower than the voltage command corresponding to the maximum value of a load driving AC current outputted from an inverter by a voltage command clamping circuit. CONSTITUTION:An inverter 11 is controlled with a voltage detection signal from a voltage detecting circuit 18 for detecting the output voltage from an inverter device 11 and a voltage control signal responsive to the voltage command from a voltage instructing circuit 22 in a voltage controller 20. In a voltage command clamping circuit 24, a voltage command from a voltage command generator 22a is detected by a power voltage detector 28 at the external AC power source voltage, and is clamped at lower than the voltage command corresponding to the maximum voltage of the load driving AC current outputted from the inverter 11 by the clamping value from a clamping value generating circuit 26 in response to the detected voltage. Even if the voltage drop occurs at the AC power source, the voltage controlling system can be thus stabilized.
