3-PHASE INTEGRATED POWERLINE COUPLING UNIT AND POWERLINE COMMUNICATION DEVICE HAVING THE COUPLING UNIT AND SURGE PROTECTOR

摘要

PURPOSE: Three apparatus for operation without error, three phase all-in-one coupling apparatus, and power line communication apparatus for including surge protection apparatus are provided to reduce a complexity metric when a power line communication apparatus connects to a number of power line channels. CONSTITUTION: A Tx coil, an rx coil, an R phase coil, a S-matrix coil and T phase coil are wound on one coupling core(700). A transmission unit is connected to the Tx coil. A receiver is connected to the Rx coil. The transmission unit and the Tx coil are each other connected from the transmission signal of the transmission unit signal to the Tx coil by transmitting differential signaling type.
