Spwm theory
WebSpace vector modulation is responsible for generating pulse width modulated signals to control the switches of an inverter, which then produces the required modulated voltage to drive the motor at the desired speed or torque. Space vector modulation is also known as space vector pulse width modulation (SVPWM). http://www.ijettjournal.org/volume-4/issue-4/IJETT-V4I4P303.pdf

WebFig.2 is an example of the SPWM with modulation index more than 1. However, due to the variation of the sine wave refer-ence values during a PWM period, the relation between refer-ence values and the carrier wave is not fixed. This results in existence of harmonics in the output voltage causing unde-sired low-frequency torque and speed pulsations.
