Abstract:
    Provided is an apparatus for adjusting the phase difference between different phases in a power line communication (PLC) system. The apparatus includes a power signal blocking unit blocking a power signal and allowing a data signal to pass between two different phases on three-phase power lines; and a data signal delaying unit delaying the data signal by the phase difference between the two different phases. Accordingly, it is possible to prevent data collision and a time delay in data transmission between different phases by employing the phase adjusting apparatus in a PLC system, thereby improving the performance of PLC.
