Abstract: The main objective of asymmetrical multilevel converter configuration is to achieve quality form of AC voltage and current by increasing the levels of output voltage. This paper mainly investigate the pro's and cod's of various dc source progression schemes like binary, quasi, trinary, etc proposed for the asymmetrical cascaded H bridge multilevel converter topologies. The performance of a 3φ, 400V cascaded Three H Bridge multilevel converter has been examined for various asymmetrical dc source progression schemes using MATLAB/Simulink and also prototype converter has been validated using dSPACE DS1103 real time interface controller.
Key words - Asymmetrical dc source progression, cascaded H-Bridge multilevel converter, %THD, multicarrier PWM
