Third-order harmonic currents suppression method based on selective component compensation for cascaded H-bridge STATCOM under asymmetric grid

Third-order harmonic currents suppression method based on selective component compensation for cascaded H-bridge STATCOM under asymmetric grid

To achieve low cost and compactness, small dc capacitance in dc-link is preferred in the cascaded H-bridge (CHB) static synchronous compensator (STATCOM). However, small dc capacitance will definitely result in high dc-link ripples among three clusters, and thus cause severe third-order harmonic cur...
