Space vector PWM for 3 leg inverters

in a svm we have to use 6switches in 3 legs. overall outage increased by svm method.THD also reduced

1.for a good inverter gain must be a high, it possible in svm 15% more compare to normal pwm.
2.inverter consumption power must be less. in svm at each sector only one switch varied. so total consumption will be reduced
3.third harmonic can be effectively eliminated by svm method.
4.no need of lookup tables for this method.
