摘要：
Boost multilevel inverters (MLIs) with front-end switched-capacitor (SC) modules are popular in applications like solar system and electric vehicles. This work proposes a three-phase SC boost MLI (TSCBI) employing single-input. The SCs are employed in parallel charging and series discharging path to create a two-fold boosted output. The SC voltage is self-balanced and maintained at half of the input voltage magnitude, which assist in synthesizing a nine-level line voltage output. Multi-carrier pulse-width modulation technique is further developed that used to control the switches. Benefits of the proposed TSCBI are justified in comparison to other SC MLIs. Including detailed operation analysis and power loss calculation, the suggested topology is validated through MATLAB/Simulink simulations under dynamic test conditions and through real-time using a laboratory-scale experimental setup.
