With active filters, a distinction is made between current-controlled and and voltage-controlled filters, which can be used to dynamically compensate several harmonics simultaneously. In addition, these active filters can also be used to dynamically compensate reactive power and reduce rapid voltage fluctuations (flicker). Flicker compensation is not a problem for the filters.
Voltage-controlled active filters are new. With these special filters, both harmonics and interharmonics of the voltage can be reduced. Due to their mode of action, they can also work impedance-controlled and are thus able to damp resonances.
We offer active filters in all power ranges from well-known manufacturers.
