| Abstract | |
This paper presents a five-level active-neutral -point-clamped converter applied as a single-phase shunt active power filter that can be used in low and medium voltage systems aiming a harmonic filtering and reactive power compensation generated by nonlinear loads in which the current control strategy is based on the Synchronous Reference Frame. Two control algorithms are proposed, in the first, a method to obtain the desired displacement power factor is presented, and the percentage of the third, fifth, seventh and ninth harmonic to be filtered also can be set. In the second, the power of the converter can be adjusted to a desired value. The system was modeled in graphical environment Simulink of the Matlab software with the SimPowerSystems Tool box. Results of computational simulations are presented in order to evaluate the proposal study and to demonstrate the performance of the system, showing that the proposed control strategy works as expected, reducing the current harmonics and the displacement power factor to the desired value.
