Comparison of different topologies of cascaded H-Bridge multilevel inverter

2013 International Conference on Computer Communication and Informatics, 2013
This paper mainly deals with three different topologies of cascaded H-Bridge multilevel inverter. The Existing Topology is a general type of multilevel inverter and has two DC sources for each phase. In Proposed Topology-I the number of DC sources has been reduced to one for all the three phases and the usage of transformers comes into picture ...
