N2 - This paper presents a novel voltage balancing modulation scheme based on the popular PSC-PWM strategy for cascaded multilevel STATCOMs. Analyzing on adjustments of the carriers in PSC-PWM, the proposed method more flexibly balances the DC-voltages from the charging process, and has no requirements for extra circuits or PI controllers. Finally, a 25-level cascaded STATCOM is constructed and tested. The proposed method solves the DC-voltage balancing problems that usually arise in the cascaded multilevel STATCOM operations, and its features and superiority are demonstrated.
