1. A power line communication (PLC) system, comprising:
a PLC signal transmitting end;
a PLC signal receiving end; and
a power electronic apparatus, wherein the PLC signal transmitting end is connected to the PLC signal receiving end through a power line, the power electronic apparatus is connected to the power line, and the power electronic apparatus is configured to
increase output impedance in a first PLC communication frequency band, and
reduce interference from an output current of the power electronic apparatus to a PLC signal in the first PLC communication frequency band, wherein the first PLC communication frequency band is a PLC communication frequency band in which the PLC signal transmitting end sends the PLC signal to the PLC signal receiving end.
