Abstract

The paper presents a novel five-phase cascade inverter control method based on the Haar wavelets transform. The inverter is built from two or three two level inverters in every phase. The instantaneous value of the output voltage of the cascaded inverter is composed as a synthesis of the selected Haar wavelets. An analytical system of determining the best possible set of Haar orthogonal wavelets is presented. On the basis of the applied Haar wavelets, the control signals of the inverter switches are calculated. The cascaded five-phase inverter with a star connected resistive-inductive load was tested during simulation tests. The results and discussion of main proprieties are presented.
