Comparative investigation of 15 Level and 17 level cascaded h-bridge MLI with cross h-bridge MLI fed permanent magnet synchronous motor

Multilevel inverters offers eminent solutions to high voltage power applications due the association of several devices in a series configuration. In this paper, comparative investigation both 15 and 17 level cascaded h-bridge multi inverter with cross fed permanent magnet synchronous motor are presented by appropriate simulations mathematical analysis. Comparative analysis includes Inverter output current, number switching devices, stator current speed PMSM total harmonic distortion levels. Limitation which can afford is major problems raised study. The advantage figure out that be used for real time application considering factors via. Harmonic distortion, voltage, etc. Validation processed through matlab/simulink platform.
