Abstract: In this paper the output of a five-level inverter-fed brushless DC motor drive is evaluated and described. Because of the many benefits of this topology, a cascaded H-Bridge inverter topology was selected for the study. On the basis of the mathematical model of the brushless DC motor, the simulation model of the motor is developed. In MATLAB/SIMULINK, the whole model of the inverter-fed drive is simulated. The inverter output voltage, engine torque, back EMF, and harmonic analysis of the inverter voltage are all seen as waveforms. With a five-level inverter, the output voltage is of high quality. According to the simulation review, the efficiency of BLDC is strong when fed by a five-level inverter, Index Terms: Brush less DC motor, Inverter, Control, Modulation of Inverter.
