Detailed Description

SVPWM Implement space vector pulsewidth modulation.

Space vector pulsewidth modulation takes the alpha and beta voltage components and enables the switches on a 6 switch inverter to drive a 3 phase AC motor. The modulation has seven pulse subperiods each pulse period. These are arrange symmetrically about the center of the pulse. A zero pulse is at the beginning, middle and end. The order of the active pulses (for the two active space vectors) is ordered differently for even and odd sectors in the alpha-beta plane. This minimizes switches.
