A control circuit for controlling a power semiconductor, the control circuit comprising a gate driver comprising a control input, auxiliary voltage inputs and an output. The control circuit further comprises a first semiconductor switch comprising a control electrode and main electrodes, a first main electrode forming a positive input pole of the control circuit and a second forming an output of the control circuit; a second semiconductor switch comprising a control electrode and main electrodes, a first main electrode forming a negative input pole of the control circuit and a second being connected to the output of the control circuit; a first resistance, a second resistance, a first zener diode whose anode is connected to the output of the gate driver and whose cathode to the positive input pole of the control circuit; and a second zener diode whose cathode is connected to the output of the gate driver and whose anode to the negative input pole of the control circuit.
