This reference design features a analog front end for DC arc detection in solar applications based on artificial intelligence (AI). The string current is measured, filtered and fed into an AI-based arc detection algorithm running on the TMDSCNCD28P55X, controlCARD of C2000™ F28P55x devices, to detect DC series arcs. AI-based arc detection offers improved accuracy and robustness compared to traditional algorithms. A complete tool chain for collecting arc data, training an embedded AI model, and validating the system is available. This reference deign is available to order through the part number TIEVM-ARC-AFE.
