Abstract

This paper introduce a seven level grid connected system based on the TRSPWM strategy and a Quasi PR current controller has a good output performance with a fast response and compensation for the low order harmonics in grid. With the multilevel output voltage and a high tracking current strategy with a low-order harmonic compensator, the grid connected system could operate properly in a polluted grid with low order harmonic. The simulation based on MATLAB verify the proposed the accuracy and feasibility of the proposed scheme.
