Solution concept of modular single phase active power filters

摘要

This paper investigates a modular or a decentralised single-phase active power filter control strategy. It is basedon the evaluation of the harmonic reference load currents for the active power filter blocks operating under specific harmonicfrequencies. The underlying principle of the modular active power filter is explained and it is shown how the requiredreference harmonic currents can be evaluated. Simulation results demonstrated the improvement in the dynamic performanceof the modular active power filter presented here in comparison with the conventional type.
