INVERTER CONTROLLER AND CONTROL METHOD OF INVERTER DEVICE

摘要

An inverter controller (4) is configured to control an inverter device (1). The inverter device is configured to generate a drive voltage of an AC load by a switching operation of a switching element connected to a reflux diode. The inverter controller is configured to perform a control of setting a switching speed of the switching element to be smaller on a lower level side of a magnitude of a current flowing in the AC load than on a higher level side of the magnitude of the current.
