Modelling of LCRC adaptive impedance matching circuit in narrowband power line communication
MetadataShow full item record
© 2015 IEEE.Power line communication technology is the wired communication technology that performs data transmission from a transmitter to a receiver using the existing electrical wiring. Even though the noise level and impedance mismatch problems of power line communication can be controlled by using a band-pass filter and an impedance matching circuit, respectively, the impedances in a power line are time and location variant. Therefore, these problems are still the main concern in power line communication. In this paper, an adaptive impedance matching circuits are proposed to allow maximum power transfer in the system at all time. The circuit is based on LCRC (inductor-capacitor-resistor-capacitor) filter, to achieve simple circuit configuration while retain high impedance matching resolution.
