Abstract
A module for an active mains filters for determining reference currents for a subsequent current adjustment control with transformation of the inflowing currents, first determines active power of the load, then directly calculates the reference currents taking into account the active power and the α-β components of the mains voltage. A module for an active mains filter for compensating one or more harmonic currents or voltages using selective signal analysis and an active mains filter for a 3-phase supply mains with a reference module for determining reference currents are also provided.
