Multilevel converters offer advantages in terms of the output waveform quality due to the increased number of levels used in the output voltage modulation. This advantage is particularly true for cascade H-bridge (CHB) converters that can be built to produce a large number of levels owing to their modular structure. When increase the number of levels it requires more number of switches, it implies the size and cost of the device increases. To overcome this problem here we present a new Hybrid Cascaded H-Bridge Multi Level Inverter with reduced number of switches, this Hybrid Cascaded H-Bridge MLI is effective & efficient in improving the quality of the inverter output voltage as well as the output Power. Here, we describe about the structural parts, switching strategy and operational principles of the Hybrid Cascaded H-Bridge MLI. The Proposed topology reduces the number of switches as well as the number of Pulse generators. The simulation is done in MATLAB/SIMULINK software and the results shown for the existing multilevel inverter & proposed multilevel inverter, THD is reduced and also better speed response.
