Abstract
An overcurrent protective device has a current detecting section and a control section. The current detecting section detects the amount of a current flowing through switching elements of an inverter device. The control section determines whether the inverter device is held in a first state or a second state in correspondence with an input from the current detecting section. When it is determined that the inverter device is held in the first state, the control section performs a flywheel operation. When it is determined that the inverter device is held in the second state, the control section performs a regenerative operation. Accordingly, the overcurrent protective device prevents generation of whine when performing overcurrent protective operation.
