How to optimize EMC for power line pollution in power line carrier PLCs?

Optimizing the EMC of power line pollution in power line carrier PLCs requires addressing harmonics, noise, and impedance variations. Adaptive filters are deployed, adjusting filter parameters based on the pollution spectrum. Spread spectrum communication technology is used to reduce sensitivity to narrowband interference. Wideband transformers are used in the coupling circuit to adapt to impedance changes. Operating modes are dynamically switched by monitoring the power line status in real time. During testing, the communication bit error rate should be below 10^-5 on polluted power lines with THD > 10%. Optimized design can ensure reliable communication on polluted power lines, improving adaptability.
