Synopsis:
This paper proposes a hybrid cascaded multilevel inverter to get a desired ac voltage from several dc voltages. These multilevel inverters are used for high power applications. These inverters give less total harmonic distortion (THD), and also can reduce the power switches when compared with conventional cascaded multilevel inverters. In general, the output of an inverter is controlled with the help of various controlling techniques. In this proposed work, these multi level inverters are controlled with modified SPWM scheme to reduce the switching losses. The objective of this paper is to evaluate the performance of an induction motor with the proposed model of fuel cell powered hybrid cascaded multilevel inverter and to control the speed of the induction motor. MATLAB/SIMULINK platform is chosen to simulate the proposed model and control technique.
