A New 2-Dimension Extendable Multisource Switched Capacitor Boost Multilevel Inverter with Reduced Components

This paper proposed a novel extendable configuration of switched capacitor boost multilevel inverter (SCBMLI) based on multisource and switched capacitor (SC). The proposed topology can boost the DC voltage sources with self-voltage balancing across all the DC capacitors via binaryasymmetric method and series-parallel connection. Specifically, it can produce 57 and 113 level of AC output voltage by using 16 and 18 number of switches, respectively. With the aim of achieving low total harmonic distortion (THD) of 5% set by IEEE Standard 519-1992 for a range of different modulation indexes (MI) (i.e., from 0.3 p.u. to 1 p.u.), this work is targeted to apply to high voltage transmission line in future for power quality improvement. In addition, by taking IEEE 1547 standard into consideration, the optimum configuration of the proposed topology to synthesize its peak AC output voltage within the tolerance boundary (i.e., from 0.95 p.u. to 1.05 p.u.) is sought after to maintain power system reliability for distributed energy resources (DER). To verify the performance of the proposed SCBMLI, detailed analysis with the variables of THD as well as the number of levels and the root-mean-square (RMS) of AC output voltage and current are simulated in MATLAB/SIMULINK Finally, a comparative assessment with recently developed topologies is performed to demonstrate the advantages of the proposed SCBMLI.
