Patent ID: 8659328

Claim:
A method for the repetitive transmission of a first signal representing a binary value via a transformer section of a driver of a power semiconductor comprising the steps of: applying, for a first value of the binary value, a first pulse packet as a sequence of a positive pulse and a negative pulse, or for a second value of the binary value, a second pulse packet as a sequence of a negative pulse and a positive pulse, to an input of the transformer; varying at the input the time interval (T R ) between two repetitively successive pulse packets of the same value in a manner dependent on a second signal to be transmitted; determining at the output the time interval (T R ) from the pulse packets mapped in the output variable (U A , I A ); reconstructing the second signal from the time interval (T R ); and applying the respective pulse packets repetitively to the transformer section; wherein one of the first value and the second value is detected at the output of the transformer from the sequence of the polarity of an output variable within a transmitted pulse packet; and wherein the respective amplitudes of the two pulses within the pulse packet are at least approximately equal in magnitude.
