Analysis of Nine-level Inverter topology with Hybrid Input Sources
This paper deals with the analysis of a nine-level multilevel inverter topology with hybrid input sources. The total number of input sources present in the topology is two which is arranged in asymmetrical arrangement. Solar PV system and fuel cell are used as the hybrid input sources to the multilevel inverter topology. The nine-level MLI is a reduced number of switch type inverter topology. The Multicarrier PWM technique is the simplest for implementation and flexibility in PWM waveforms generation for such type of MLI with hybrid input system. The construction of the MLI is done using power electronic devices which are then loaded and tested with a single phase induction motor. The operation of the multilevel inverter, induction motor and the hybrid sources are analysed. The simulation work is done in MATLAB Simulink and the results are verified. The system is tested with a real time prototype and the output is verified successfully.
