摘要： A method for actuating an electrical circuit arrangement including at least one switching element. The switching element is actuated by a driver circuit as a function of switching-signal information for switch-on and switch-off. The switching-signal information is continuously determined and a switch-on period and signal position information are specified respectively for at least one switching-signal time window with a fixed duration. The position of the switch-on signal within the switching-signal time window is specified by the signal position information for a switch-on signal that results from a switch-on period that is less than the duration of the switching-signal time window.

摘要： A method for operating a drive device for a motor vehicle is provided, wherein the drive device has an electric machine which is electrically connected to a DC power source via an inverter controlled by means of pulse width modulation. The pulse width modulation is performed depending on a predetermined duty cycle. When the duty cycle that is less than a threshold value, a continuous pulse width modulation is used to control the inverter. The pulse width modulation is switched to a discontinuous pulse width modulation when the threshold value is exceeded. A motor vehicle and a drive device for a motor vehicle are also provided.
