In this study, a nine-level cascade multilevel inverter (CMI) employing multicarrier pulse width modulation (PWM) methods is investigated in detail to achieve higher voltage levels. The results of the simulation verify the core operational concept of the CMI. Various modulation techniques are used to compare the phase and line voltage total harmonic distortion (THD) performance. With a focus on its application in STATCOM (Static Synchronous Compensator) systems, the paper explores the notable applications of CMI. Specifically, a communication system with a multilayer H-bridge converter arranged in a star configuration is examined. Also discussed is a generalized per-phase DC-bus voltage balancing technique based on capacitor voltage balancing (CVC) for CMC-based STATCOMs. In order to provide light on the underlying workings of the system and improve performance, the research first applies the dq/abc park transformation before doing an open-loop transfer function analysis. This research contributes to the advancement of multilevel inverter technology by shedding light on operational principles and optimization strategies, particularly as they relate to STATCOM applications.
