Products
The active power filter (APF) is mainly composed of controller, isolation switch (circuit breaker), contactor, IGBT, driving circuit, protection system, fuse, connection reactor, DC capacitor, etc. The controller measures phase A, C reactive power(current), produces control signal, drives IGBT on/off and produces harmonic and reactive current same as system harmonic current but in opposite phase to filter system harmonic, reduce reactive power and keep system power factor approximately at 1.
Features
Our APF equipment is module structure, there are two types Wall Mounted and cabinet mounted. The Wall Mounted type is preferred to be used in equipment improvement which is very convenient to install. The VISHAYD Modular Active Harmonic Filter series are suitable for applications of all types, providing harmonic mitigation, load balancing and step-less reactive power compensation for inductive and capacitor loads.
