Abstract:

© 2020 The Institution of Engineering and Technology. Switched capacitor multilevel inverter (SCMLI) with reduced components is attractive for higher number of voltagelevels due to less implementation complexity and low cost. In this study, a new family of hybrid SCMLI for high frequency powerdistribution system is presented to eliminate the intermediate power conversion. Firstly, a five-level SCMLI employing a singlevoltage source is proposed, which is further extended to nine-level (9L) with its operation. Further extension/enhancement of theproposed 9L-SCMLI for generating a higher number of voltage levels with reduced number of components is achieved on thebasis of structural modification. The mathematical analysis for determination of capacitance, power loss analysis andcomparative analysis has been provided in detail. A comprehensive comparison with other similar topologies is also provided tohighlight the merits of the proposed topology. Simulation and experimental results are discussed for various dynamic loadconditions with different output frequencies to validate the suitability of the proposed SCMLI for various high-frequency ACapplications, such as renewable energy systems, microgrids, electric vehicles and so on.
