Abstract. In this paper. we present a comparative study of the performances of the multicells series and the Neutral-Point-Clamped (NPC) three-level converters used at synchronous static compensators (STATCOM) for the control of the voltage at a point of the network. The analysis consists on a mathematical modeling. https://www.hindigyanvishv.com/hot-save-Herbstonne-Black-Eyed-Susan-big-savings/
