Abstract: A galvanically separating interface for transmitting electrical energy and data packets is based upon the clocked polarity reversal of a primary coil such that a corresponding alternating voltage signal is induced in a secondary coil. The primary coil is separated from the supply voltage or ground after each polarity reversal per cycle for a defined dead time. Electrical pulses are generated in the primary coil within dead times and correspond to the data packet to be transmitted. By rectifying the alternating voltage signal induced in the secondary coil, the transmitted energy can be used. Simultaneously, the pulses generated on the primary side can be detected via the secondary coil in accordance with the transmission standard as the data packet to be transmitted. This use of dead times as a “bit” enables a rapid data transmission rate which corresponds to the polarity reversal clock rate.
