Analysis of switched inductor Z-source modified cascaded H-Bridge multilevel inverter
To overcome the restriction of buck operation in VSI and to get extra boosting capability, with same set of switches, a new topology in the family of Z source fed multilevel inverter is developed and presented in this paper. An advanced dc-dc enhancement technique, called switched Inductor is included to develop this new topology. This topology is developed by replacing switched inductor cell instead of normal inductor in Z source modified cascaded multilevel inverter. This set up provide high boost factor compared to existing Z source cascaded H bridge multilevel inverter ZS CHB MLI. High voltage conversion ratio obtained by short shoot through helps in improving the quality of the output power of the main proposed circuit. Enlarged voltage boosting capability, from low ac voltages to higher ac voltages is possible in this topology. It has wide application in ac-ac, dc-dc, dc-ac, ac-dc power conversion.
