Controlling the Vienna rectifier using a simplified space vector pulse width modulation technique
In this thesis, a simplified Space-Vector Pulse-Width-Modulation (SVPWM) technique for the Vienna rectifier is introduced to reduce the computational burden, the switching losses and the Total-Harmonic-Distortion (THD). Furthermore, the robustness of this modulation technique is tested under …

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. …
