I am trying to understand SVPWM logic developed by ST, from mc workbench, i referred the documentation provided. But its much unclear in the documentation as well why and what variables are being used for. I want to know the reference of the literature discussed in the documentation (see image).
Function: PWM_SetPhaseVoltages()
My queries:
What is the logic of X,Y,Z for calculating sector? Reference ? Instead of using simple tan-1(Vbeta/Valpha).
Thanks in advance.

Anyone at ST?

Hi Cedric, I have gone through this book but haven't found any specific reference regarding SVPWM as mentioned in documentation regarding logic of X,Y,Z for calculating sector. Can you please be more specific?

Online so much information available on how to calculate the timings of svpwm and then duty cycles which are applied to the motor phases.

I know about timing and duty cycle calculations, I have asked about logic of deciding sectors based on X,Y,Z.
