Transmission of actuation signals and data signals

A method for transmitting an actuation signal and a first data signal between a control device and an actuation device for a power semiconductor device, said method comprising:

• transmitting the actuation signal and the first data signal from the control device to the actuation device simultaneously and via a common transmission channel;
• combining the first data signal with the actuation signal by means of a digital modulation method or coding method;
• transmitting a feedback signal together with a second data signal in the opposite direction;
• using a first coding length which is shorter than the interval length of the actuation signal for the first data signal;
• and
• using a second coding length which is shorter than the interval length of the feedback signal for the second data signal.

An arrangement, comprising:

• a transmitter including a mixing device provided for combining an actuation signal with a first data signal and for combining a feedback signal with a second data signal;
• a transmission channel provided for transmitting the combination of the actuation signal with the first data signal and transmitting receiving the combination of the feedback signal with the second data signal;
• and
• a receiver provided for receiving the combination of the actuation signal with the first data signal and for receiving the combination of the feedback signal with the second data signal.

A system, comprising:

• a control device;
• an actuation device interacting with the control device for digital transmission of an actuation signal and a first data signal in one direction and for digital transmission of a feedback signal together with a second data signal in another direction opposite to the one direction;
• an arrangement a transmitter including a mixing device provided for combining an actuation signal with a first data signal and for combining a feedback signal with a second data signal, a transmission channel provided for transmitting the combination of the actuation signal with the first data signal and transmitting receiving the combination of the feedback signal with the second data signal, and a receiver provided for receiving the combination of the actuation signal with the first data signal and for receiving the combination of the feedback signal with the second data signal;
• and
• a power semiconductor device actuated by the actuation device with an analog actuation signal.
