Abstract
Cascaded split-source inverter (CSSI) is a new single-stage modular multilevel topology. Each cell of this converter converts DC to AC power in the buck or boost operation mode without any additional power switch. This paper develops a design method based on a detailed model for CSSI. This model shows that energy storage elements experience double-fundamental frequency ripples besides high-frequency ones. It accurately calculates voltage gains and capacitor voltage and inductor current ripples. On the other hand, common carrier-based multilevel modulations have been modified in terms of both reference and carrier signals to control the inverter under symmetric and asymmetric conditions. With...
