Abstract
This paper presents the design and control of multilevel inverter fed brushless dc (BLDC) motor drive. Diode clamped multilevel inverter is designed and verified with BLDC motor at different speeds. The multicarrier PWM technique can be implemented for producing low harmonic contents in the output, hence the high-quality output voltage was obtained in the proposed system. The validation of the neutral clamped multilevel inverter-based BLDC motor drive system is verified in the MATLAB/Simulink software environment.
