Abstract
An actuation circuit for an inverter includes a direct voltage converter to convert direct current at a first voltage into direct current at an intermediate circuit voltage, and a driver unit that generates inverter control signals, based on direct current at the intermediate circuit voltage, to switch elements of the inverter. The actuation circuit also includes a discharge unit supplied with direct current at the intermediate circuit voltage, where the discharge unit switches, in response to a discharge control signal, a discharge resistor in parallel to an output of the direct voltage converter, and a control unit that is supplied with direct current at the intermediate circuit voltage. The control unit is configured to generate, for the discharging of the back-up capacitor, a discharge control signal that causes the discharge unit to switch the discharge resistor in parallel to the output of the direct voltage converter.
