Beschreibung
Zusammenfassung:	The invention relates to a circuit arrangement for controlling an electric machine, in particular an electric motor and/or a generator. The circuit arrangement has at least one power module and a processing unit. The power module has at least one semiconductor switch half bridge which is connected to an output terminal for a stator coil. The processing unit is designed to control the half bridges for energising the stator of the electric machine for generating a magnetic rotating field. The processing unit is designed at least to generate a control signal. The processing unit is connected to the power module via a voltage supply line. The circuit arrangement also has a modulator connected to the processing unit. The modulator is designed to generate a carrier signal and to modulate the control signal onto the carrier signal and to feed the modulated carrier signal into the voltage supply line. The circuit arrangement also has at least one modulator which is connected to the power module, is connected on the intake side to the voltage supply line, and is designed to demodulate the control signal from the modulated carrier signal and to send the control signal to the semiconductor switch half bridge.
