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.roneverhart.com/Phenix-First-Due-EMS-Responder-Helmet/
