Abstract:
A three-phase shunt active filtering algorithm based
on the real component of fundamental load current(I cos )has
been proposed and implemented in a novel manner in this paper.
The complete simulation and hardware implementation of the active filter (AF) with the proposed algorithm has been presented.
Simulations have been performed for various dynamic operating
conditions under balanced/unbalanced nonlinear reactive loads for
both balanced as well as unbalanced/distorted source conditions.
The AF has been realized by means of a hysteresis current-controlled voltage-source inverter (VSI). The experimental setup is
controlled by making use of simple op-amp-based analog circuits
and digital signal processor ADMC401. Experimental results have
been obtained for different load and source conditions and discussed in detail. The response of the AF system in simulation as
well as in hardware proves the effectiveness of the proposed control technique
