Comparison Between PWM and SVPWM Three-Phase Inverters in Industrial Applications
… three-phase space vector pulse width modulation (SVPWM) inverter. SVPWM inverters utilize a space vector (reference vector) to create the desired sinusoidal waves. SVPWM proved to have less total harmonic distortion (THD% = 1.15%) and faster response time (114ms) with an output error of 0.13V. …

Space vector pulse-width modulation for multilevel inverters and solution to modulation dependent problems
The Space vector PWM (SVPWM) is a prominent modulation technique for multilevel inverters similar to two-level inverters. However, due to complex geometry of the space vector diagram and a large number of switching states, the implementation of SVPWM for multilevel inverters is considered complex. …
