摘要： 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.

Also, the power converter includes a transformer disposed between the primary bridge unit and the secondary bridge unit and configured to magnetically couple the primary bridge unit to the secondary bridge unit. Additionally, the power converter includes a current sensor configured to measure instantaneous current flowing at an input terminal of the transformer. Furthermore, the power converter includes a cyclic state controller configured to receive the measured instantaneous current flowing at the input terminal of the transformer, and change a switching state of the power converter from a present switching state to a subsequent switching state based on the measured instantaneous current.

摘要： The power output of an RF plasma supply device is controlled by producing at least a first and second RF power signal by means of a respective RF generator, coupling at least two RF power signals into a coupled RF power, and distributing the coupled RF power between a plasma power that is to be supplied to a plasma load and an equalizing power that is to be supplied to an equalizing load. The power output is controlled by adjusting the levels and/or the phase position of the RF power signals in such a manner that, for plasma power in the range between a predefined lower power limit and a predefined nominal power, an insignificant portion of the coupled RF power constitutes the equalizing power and, for plasma power below the predefined lower power limit, a significant portion of the coupled RF power constitutes the equalizing power.
