Abstract
An inverter control device includes a DC power supply for outputting a first DC voltage, a voltage conversion unit for converting a voltage level of the DC voltage and supplying a first DC voltage to an inverter, a temperature detection unit for detecting an ambient temperature (element temperature) of the inverter, and a control device. The control device controls the voltage conversion unit such that the voltage VH lowers as the ambient temperature is lower, based on a temperature value representing a result of detection by a temperature sensor. A tolerable surge amount can thus sufficiently be ensured at a low temperature.
