Abstract: A method for dead time optimization of MOSFETs in an inverter of an motor controller of an electric motor in an electromechanical motor vehicle power steering mechanism or a steer-by-wire system. The inverter includes at least two MOSFETs comprising a high side MOSFET and a low side MOSFET, and wherein the motor controller controls the at least two MOSFETS with gate driver signals with a dead time. The dead time represents a time of the MOSFETs for switching over from one MOSFET to another MOSFET connected in series. The method includes the steps of measuring a cross conduction between the high side MOSFET and the low side MOSFET in a current measurement unit, and when a cross conduction occurs the dead time is increased, otherwise the dead time is decreased.
