Abstract:
Device for operating an electric motor, comprising a detection unit for detecting zero-crossings and phase angles of applied phase-shifted sinusoidal voltage phases of a multi-phase power supply network; and a switching unit for connecting half-waves of the applied sinusoidal voltage phases through by means of semiconductor switches in accordance with switching patterns applied to the semiconductor switches, said patterns being synchronised with the detected phase angles and zero-crossings, to generate phase-shifted quasi-sinusoidal voltage phases which are applied directly to the electric motor.

Claim (Index 7):
Device for operating an electric motor, in particular of a three-phase asynchronous motor, comprising:\n a detection unit for detecting zero-crossings and phase angles of applied phase-shifted sinusoidal voltage phases of a multi-phase power supply network; and a switching unit for connecting half-waves of the applied sinusoidal voltage phases through by means of semiconductor switches in accordance with switching patterns applied to the semiconductor switches, said patterns being synchronised with the detected phase angles and zero-crossings, to generate phase-shifted quasi-sinusoidal voltage phases which are applied directly to the electric motor, wherein the switching unit is a hybrid switching unit, which has mechanical contacts which are connected in parallel with the semiconductor switches of the switching unit, wherein a control unit ( 6 ) is provided, which actuates semiconductor switches of the switching unit in accordance with the switching patterns read out from a data store, wherein to start up the electric motor the frequency of the quasi-sinusoidal voltage phases is stepped up incrementally by the switching unit by changing the switching patterns applied to the semiconductor circuits until the network frequency of the voltage supply network is reached, wherein after the network frequency of the power supply network is reached the electric motor is supplied directly by the power supply network, via mechanical contacts connected in parallel with the semiconductor switches.
