SiC MOSFET Active Harmonic Filter for Industrial THDi Correction A textile mill in Vietnam replaced its capacitor banks three times in 18 months. Each failure followed the same pattern: capacitor cans bulged, contactors welded shut, and fuses blew during the afternoon shift when 85% of the VFD-driven spinning frames ran simultaneously. The plant needed a SiC MOSFET active harmonic filter to solve ...
How to Reduce Electrical Losses in Industrial Power Systems Electrical losses raise operating costs, heat cables and transformers, and reduce available system capacity. They usually result from conductor resistance, inefficient loading, poor power factor, harmonic currents, and aging equipment. To reduce electrical losses in industrial power systems, engineers need accurate measurements, correct e...
