Space Vector PWM

Emmanuel_20824

Hello
I am a student and I study voltage inverters with the PSIM software provided by our university.

I would like if anyone would know the internal schema of one of the SVPWM blocks pre-provided by PSIM.

This one or this

Indeed, in the Help menu I only get the explanation of how the block works, the diagram would be used to do the assembly.

Thank you in advance for your answers.

Emmanuel

Hi, Emmanuel,

In the "Help", the math equations and vector diagrams are also provided to explain the principle of operation.

Please clarify "the diagram would be used to do the assembly."

Do you want to build a circuit to implement the same functions?

Sincerely,

Rhonda

Hi, Rhonda,

Thanks you for your answer.

Yes, I would like to build a circuit to implement the same functions instead of using the already ready-made SVPWM block.

Indeed, I read the "Help" that explains how it works.

Sincerely

Hi Emmanuel,

In general PSIM implements the algorithms for the TI DMC library page 193 (pdf page 197) gets into the theory.

If you go through the math you end up with something like this.

in the DC-AC example folder there is a multi-level implementation with level shift

Hi Albert,

Thank you for your reply. I was able to implement the SVPWM block.

So with that, I applied the Clarke transformation to do the implementation with Alpha and Beta input which are out of phase by 90°.
Thank you.
