Abstract

This paper compares various modulation techniques of twolevel
inverter, i.e 180 conduction method, Sin-PWM (SPWM) and
space vector PWM (SVPWM). Simulation result shows that 180
conduction mode is able to generate the highest voltage output
however it results the worse performance. Comparison of
fundamental component of the output voltage is 0.637 : 0.5 : 0.57
p.u for 180 conduction method, SPWM and SVPWM respectively.
Meanwhile comparison of voltage output THD is 31% : 68% : 30%
and comparison of phase stator current THD is 50 % : 24% : 9.7%
for 180 conduction method, SPWM and SVPWM respectively.
Furthermore, relationship of speed - torque shows that when motor
is fed by inverter using 180 conduction method, motor is able to
reach the highest speed (1765 rpm) but results high torque ripple
compare to SVPWM (1685 rpm) and SPWM (1460 rpm). It is also
shown that the SVPWM method performs the smoothest torque
ripple among the three modulation methods. The results prove that
SVPWM method is the most suitable method for variable speed
drive of a three-phase induction motor.

Keywords— 180 conduction method, SPWM method, SVPWM method, Total Harmonics Distortion (THD), Three-phase induction motor speed drive.
