How to ensure EMC (Electronic Content Compatibility) of PLC under full load for power line carrier communication?

To ensure EMC (Electronic Motion Compatibility) of power line carrier PLC communication under full load, the impact of load variations must be considered during the design phase. Under full load, power supply noise may increase, requiring enhanced power supply filtering, such as using a power inductor PWR6045R6R8M0T and low-ESR capacitors. The communication interface experiences increased drive current under full load, potentially increasing radiation; therefore, signal integrity must be maintained through terminal matching. Simulation analysis of EMC performance under full load is crucial for design optimization. In actual testing, conducted and radiated emissions tests under full load conditions should be performed, and standard limits must be met. Ensuring full-load EMC guarantees product stability and reliability in real-world use.
