Comparison of 9-level switched capacitor based multilevel inverter with conventional 9-level CHBMLI:

Abstract

This manuscript presents the comparison of 1-ϕ 9-level cascaded H-bridge multilevel inverter and 9-level Switched capacitor based multilevel inverter. To cheer the quality of inverter’s output parameters primarily THD and switching losses, multicarrier phase shifted technique is consider for controlling the gate pulse of 9-level inverters and the complete analysis of THD for 9-level is done. This work is performed and results are validated using MATLAB/SIMULINK.
