Patent AT-E400929-T1: [Translated] ADAPTER FOR COMMUNICATION VIA POWER SUPPLY LINES

An adapter for communicating over power line is disclosed. An adapter for communicating over power line of the present invention is comprised of a transmitting unit, comprising a power supply including a transformer, a plurality of rectifiers, and a smoother, an oscillator for oscillating a carrier frequency for signal transmission, a switching unit for switching in response to a signal transmitted from a modem, a first coil, positioned between the switching unit and the oscillator, for combining the carrier frequency and data transmitted from the switching unit and magnetizing the combined result; and a first pulse transformer comprising first and second denser electrodes, which are induced electromagnetically by the firs coil and separated mutually and electrically by means of dielectrics or insulators, including first and second lead lines respectively, each connected to the power lines for signal transmission, and a receiving unit comprising a second pulse transformer having a reverse structure to the first pulse transformer a filter for passing the carrier frequency of data among signals output from the second pulse transformer, and a data separating unit for separating transmission data between the filter and the modem.
