Title:
POWER LINE COMMUNICATION SYSTEM, POWER ELECTRONIC APPARATUS AND INTERFERENCE SUPPRESSION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/222149
Kind Code:
A1
Abstract:
Provided in the present application are a power line communication (PLC) system, a power electronic apparatus and an interference suppression method. The PLC system comprises a PLC signal sending end, a PLC signal receiving end and a power electronic apparatus, wherein the PLC signal sending end is connected to the PLC signal receiving end by means of a power line, and the power electronic apparatus is connected to the power line. The power electronic apparatus is used for increasing an output impedance at a first PLC frequency band, so as to reduce the interference, at the first PLC frequency band, from an output current of the power electronic apparatus to a PLC signal, wherein the first PLC frequency band is a PLC frequency band at which the PLC signal sending end sends the PLC signal to the PLC signal receiving end. By means of the embodiments of the present application, the interference, at the first PLC frequency band, from the power electronic apparatus to a PLC signal can be reduced without additionally adding a passive filter element.
