Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An inverter control device comprising: a voltage detector configured to detect a direct-current voltage of an inverter that converts a direct-current power input from a direct-current power supply into an alternating-current power; a target value calculation section configured to calculate a target value of an alternating-current output from the inverter based on a detection voltage detected by the voltage detector; an inverter control section conf…
