Hi Loc,
The space vector modulation (SVM) technique processes the reference voltage vector to produce suitable gate signals for the inverter during each PWM cycle, aiming to maintain a continuously rotating space vector.
For each PWM cycle, using the voltage as input, the SVM algorithm performs the following steps:
- Computes the on and off gating times based on the reference voltage vector.
- Utilizes these gating times to create double hump modulation waveforms.
- Employs the gating times to generate the correct gate pulses for the inverter switches.
For more information regarding the algorithm, refer to the article:
I hope this helps.
