How to adapt to EMC in complex power grid environments for power DTUs?

Adapting to complex power grid environments requires dynamic adjustment and enhanced EMC protection for DTU systems. Adaptive filtering technology is employed, adjusting filter parameters based on the power grid noise spectrum. Wide-range voltage range power modules (85-265VAC) are deployed to withstand voltage fluctuations. Surge protection is enhanced using a three-tiered protection network. On the software side, noise monitoring and adaptive communication parameters are implemented. Field testing records typical interference patterns, leading to design optimization. After adaptation, the system should operate stably under complex environments with harmonics and voltage drops, with a communication error rate below 10^-5. This adaptive design improves the product's applicability in harsh power grids.
