Abstract :
This paper first presents a simple control technique for active filters to compensate current harmonics and reactive power of nonlinear loads. This method is usable for both single-phase and three-phase systems. Then a new method for load balancing and reactive power compensation for unbalanced sinusoidal load currents is presented. Finally by combination of two methods an active filter control method for eliminating load current harmonics and reactive power compensation is achieved. Simulation results demonstrate the feasibility of proposed methods. Suggested method is expected to be used in future for active filter designs produced for load compensation.
