The maximum voltage is increased by 15%. Under sinusoidal PWM modulation, the maximum line-to-line voltage is equal to sqrt(3)/2*Vdc, whereas under SVM, the maximum is Vdc. 1/(sqrt(3)/2) = 1.15.

what is the meaning of dc voltage utilization factor

Ahmed Belkheiri

In the SVPWM we say the forbidden region and not the ovetmodulation region. theoretically and by simulation yes but practically is difficult, moreover, the use of this region will increase the THD.
