Clarifications regarding the SVPWM Generator (2-Level) block

Hello,

I’m working with the SVPWM Generator (2-Level) block, but I’m getting the warning shown in the attached image. Should the Alpha–Beta inputs be normalized with respect to the DC link? I’ve tried doing so, but the message still appears. My simulation is discrete, with a sample time of 2e-6.

Best regards,

Fabián

Would be helpful to attach a model where the problem can be reproduced.

Without seeing the model is difficult to point to exact problem. However, from the error message is clear that some inputs to a lookup table are out of range. I believe what may have happened is that either alpha, beta, or both inputs are NaN which will trigger this warning. Double check how these signals look. I hope this helps.
