Reference for SVPWM

[tejas_amp]

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?

Thanks a lot !!

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.
