| Abstract |
A simple control scheme for an active power filter implemented with a three-level NPC voltage-source inverter is presented and analyzed in this paper. The proposed scheme compensates simultaneously displacement power factor and current harmonics. The advantages of using a three-level VSI are based in improving the compensation characteristics and reaching a higher voltage level. The control scheme is discussed in terms of priciples of operations under steady state and transient conditions. The proposed control scheme presents a new technique to generate the required current reference signals and to keep the inverter dc voltage constant. Simulated results prove the viability of the proposed scheme, which are validated by experimental results. |
