Abstract:-This work concern about two tasks related to the working and performance of space
vector pulse width modulation; understanding the principle of space vector modulation and
investigating the harmonic performance of the two-level voltage source inverter. Space Vector
Pulse Width Modulation (SVPWM) is basically a modulation technique based on modulation of
input dc signal (constant value) into output pulses of different width and different, usually 5 or 7,
amplitude levels thus generating an AC signal which could be smooth out by proper filtering or
selecting a proper inductive load. Space vector modulation scheme is superior to Pulse Width
Modulation (PWM) scheme because there are two main problems in PWM, harmonic distortion
and switching speed, and both of these problems are overcome by implementation of the SpaceVector PWM (SVPWM) technique. Two level inverters are investigated by means of their
harmonic distortion. This proposed work introduces an improved version of space vector
modulation by using a modified two level voltage source inverter for eliminating the even-order
harmonics.
