Title:
INVERTER CONTROL DEVICE AND INVERTER CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2012/039258
Kind Code:
A1
Abstract:
An inverter control device comprising: a voltage detection means for detecting the direct-current voltage of an inverter (6) that converts a direct-current power input from a direct-current power supply into an alternating-current power; a desired value calculation means for calculating a desired value of the alternating current output from the inverter (6) on the basis of a detection voltage detected by the voltage detection means; an inverter control means for generating a control signal for a switching element involved in the inverter (6) on the basis of the detection voltage and the desired value to control the inverter (6); an abnormality detection means for detecting the occurrence of an abnormality in the voltage detection means; and a voltage clamp means for clamping a detection voltage to be used for calculating the desired value at a first assured voltage and a detection voltage to be used for generating a control signal is clamped at a second assured voltage that is higher than the first assured voltage when the abnormality is detected by the abnormality detection means, wherein the first assured voltage is determined on the basis of the lower limit area of an assured voltage range that assures the performance of the inverter (6).
