Nine Level MLI fed Single Phase Induction Motor Drive with Compressor Load Using Artificial Neural Network

electrical machines and drives
Recent developments in power electronics and power semiconductor drives have improved AC-AC power conversion methods related to AC drives. Rectifier- multilevel inverters (MLIs) find their way in connecting AC source and induction motor. In AC compressor system, MLI fed induction motor is preferred because of low harmonic content. The Artificial neural network controller (ANNC) is employed for an MLI fed induction motor drive to improve the good dynamic response. The MLI also provides the better total harmonics distortion (THD). The proposed ANNC is compared with proportional integral (PI) and ANNC provides the superior performance compared with the PI controller. The proposed ANNC has been verified with MATLAB/Simulink and laboratory test has been done using the PIC16F84- microcontroller. Theoretical analysis, simulation and experimental results have established the feasibility of the developed ANNC.
