Paper Title
Simulation Study Of Single Phase Induction Motor Performance Using Multilevel Inverter
Abstract
This paper deals with the analysis of
induction motor supplied by multilevel inverter
(MLI). Generally, the poor quality of voltage and
current of a conventional inverter fed induction motor
is obtained due to the presence of harmonics and
hence there is a significant level of energy losses.
These losses can be reduced using multilevel
inverter. In inverters by increasing the number of
steps it generates the very high quality of the output
voltage and current. By increasing the number of
steps in output voltage, harmonics is reduces and
significant level of energy losses is also reduced. A
constant frequency multicarrier phase disposition
PWM technique is implemented for the Cascaded
MLI. Phase Disposition Sinusoidal Pulse Width
Modulation (SPWM) technique is used for
controlling frequency and voltage of MLI. The
simulation is carried out using
MATLAB/SIMULINK.
