An increasing number of loads are non-linear, introducing harmonics into the power grid and thus significantly impairing the power quality. EPCOS PQSine™ is anactive harmonic filter that effectively reduces the unwanted harmonics.
Linear loads have become a rarity in industrial plants, office buildings, data centers or even private households. Non-linear loads, by contrast, have become increasingly common: frequency converters in drive systems, the large numbers of switch-mode power supplies used in IT and communications equipment, and also more and more in household electronics. Even lighting technology employs mainly non-linear power supplies
