PROBLEM TO BE SOLVED: To provide a drive circuit with a transmission circuit and a method for operating.SOLUTION: The present invention relates to a method and a drive circuit with a transmission circuit which transmits a signal from a first potential side having a first grounding potential to a second potential side having a second grounding potential via a potential barrier and includes a transmission device operating in a capacitive manner while having capacitive coupling between the first and second potential sides. The transmission device includes only one or two branch lines, and each of the branch lines has first and second partial branch lines, respectively. The capacitive coupling between the first and second potential sides is formed from a serial circuit including a plurality of first and second high-voltage capacitors by the partial branch lines, and each of the high-voltage capacitors forms the serial circuit with the allocated capacitor at the second potential side. Within each of the transmission branch lines, a signal is present directly in the first partial branch line and is present via a second inverter in the second partial branch line. In the case where there are two branch lines, an inputted signal is present directly in an ON transmission branch line and is present via a first inverter in an OFF transmission branch line. |
