Adaptive impedance matching circuit for narrowband power line communication
MetadataShow full item record
The noise level and impedance mismatch are still the main concerns in the narrowband power line communication (NB-PLC) technology. The low voltage power line network has impedances that are time and location variant. So it is difficult to achieve maximum power transfer all the time. Thus two new adaptive impedance matching circuits are proposed for NB-PLC. These methodologies are derived from the RLC and LCRC circuit model to achieve simpler configuration and higher matching resolution.
