2Space vector pulse width modulation technique

One of the most popular modulation approaches for two-level converters is space vector pulse width modulation (SVPWM), which is increasingly being used in the control of multilevel converters. This is an advanced and computation-intensive PWM technique. The SVPWM increases the output capability of sinusoidal PWM without distorting the line-to-line output voltage waveform.

The concept of space voltage vectors corresponding to various switching states has been applied in the study of impact of various switching states on the capacitor charge balancing. An advantage of the SVPWM is the instantaneous control of switching states and the freedom to select vectors in order to balance the NP. Additionally, ...
