The following paper, introduces a synchronous compensation (STATCOM) based on a 9-level Cascaded Multilevel Inverter (CMLI) using a phase-shifted PWM technique. The STATCOM used here is controlled such in order to provide the reactive power compensation at the point of common coupling (PCC) for a R-L lagging load. The PS-PWM is used for minimizing the harmonic content of the CMLI terminal voltage. The d-q axis transformation is used for decoupling the active and reactive power components for simplifying the compensating power regulation. Double loop control strategy consisting of PI controllers is employed, for achievement and maintenance of nominal load bus voltage and a faster dynamic response.
