Abstract:
1. 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 determining at the output the time interval (T reconstructing the second signal from the time interval (T 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.
