Abstract

This paper highlights the critical need to address the access impedance in power supplies used in power line communication (PLC) modems. Low values of access impedance of power supplies can significantly attenuate PLC signals at both the transmitter and receiver nodes, leading to substantial degradation in performance. To mitigate this issue, we propose a modified boost power factor correction circuit capable of enhancing the access impedance magnitude of power supplies in PLC modems across a frequency band ranging from 0 to 500 kHz. Numerical analyses show the effectiveness of our proposal in comparison to other existing circuits. Furthermore, these results suggest promising directions for further enhancements in the performance of PLC systems.
