The pursuit of perfect power quality is undergoing a fundamental shift, driven by a new semiconductor material: Silicon Carbide (SiC) . Comparing a traditional Active Harmonic Filter (AHF) with a SiC-based model reveals more than incremental upgrades; it showcases a leap in performance, efficiency, and capability. For decades, traditional AHFs have relied on silicon-based IGBTs. These components w...
A robotic welding cell can run perfectly for hours and still expose a serious weakness in the factory power system when several lines start together. The symptom may be a hot neutral conductor, a nuisance trip, a voltage complaint from a servo drive, or a transformer that operates above its expected temperature. In many cases, the root cause is not a single defective machine. It is three-phase loa...
