Abstract
An inverter control device includes a voltage detector, a target value calculation section, an inverter control section, an abnormality detector and a voltage clamp unit. The target value calculation section calculates a target value of an alternating current output from the inverter based on a detection voltage. The inverter control section controls a switching element of the inverter based on the detection voltage and the target value. The abnormality detector detects an abnormality in the voltage detector. The voltage clamp unit holds the detection voltage, for calculating the target value, at a first assured voltage determined based on a lower limit area of an assured voltage range that assures an operation of the inverter: and holds the detection voltage, for generating the control signal, at a second (higher) assured voltage, upon detecting the abnormality in the voltage detector.
