Performance Analysis Of Modular Vs Non Modular Multilevel Inverter

The research article compares performance analysis of modular and non modular multilevel inverter in various aspects like, topology design, input voltage i.e. symmetric or asymmetric, objectionable components count reduction, modulation index (m), stair case voltage levels, corresponding current wave, Total harmonic distortion (THD). Generally modular design it exhibits the voltage ratio are in same, type of devices utilized will remains same, whereas in non-modular the voltage ratio and switching devices will be varying time to time. This paper compares two modules for both modular and non modular design (a) Module - I A flexible rung ladder structured multilevel inverter (FRLSMLI) (b) Module - II A new tapped sources stack succored modified HX bridge multilevel inverter (TSSSMHXMLI). To validate the viability of the system based on performance metrics, simulation and experimental are carried out and compared the same.
