PowerAct is the 2nd generation of active harmonic filters (AHF). Unlike passive filters that require initial studies of network harmonics, PowerAct Harmonic automatically detects harmful harmonic currents at the connection point and cancels them by injecting opposing currents.
PowerAct features a 3-level inverter topology, which reduces energy losses by 30% as compared to other 2-level topologies. It has a 50% higher energy density and can operate on a continuous line voltage up to 800V. These features make it more robust than other harmonic filters designed to operate up to 480V or 600V.
PowerAct improves power quality by mitigating harmonics, correcting flickers, balancing loads, and compensating for poor power factor, making it a part of and a core building block of a smart grid solution.
Typical applications include large non-linear loads like 6- and 12-pulse variable frequency drives, DC drives, and other switch-mode power supply equipment.
