The invention relates to a control unit (40) for driving an electric load, in particular an electric machine, having a first and a second voltage terminal (46, 48) in order to supply the control unit (40) with electrical energy, a capacitor (58), which is connected between the voltage terminals (46, 48), at least one half-bridge (15), which is connected between the voltage terminals (46, 48), wherein the half-bridge (50) has two controllable switches (52, 54), between which there is formed a half-bridge tap (50) for connecting the load, a safety circuit (66), which is designed to close one of the controllable switches (52, 54) of the half-bridge (50) in the event of a fault, a discharge circuit (68), which is designed to connect the voltage terminals (46, 48) electrically in the event of a fault, and having a control circuit (18) which is designed to provide a control signal (78) which triggers the safety circuit (66) and the discharge circuit (68) in the event of the detected fault.
