Space Vector PWM Calculations

You are still trying to get this to work. Well, you are tenacious. This is a big bite to take for a first project. I hope that you will use low voltage power section for the test. This could be dangerous.

Here are a few details to point you in the right direction. Note that I am not an expert in this technique. I use something else to control my converters.

NOBODY will give you the steps in detail. It is too complicated for an email. You will need a few years of work to master this technique even if your first prototype might work in a few months.

Some people use a PLL to generate a Vref that correspond to the line voltage or the motor internal rotating field depending on the converter / inverter application. Other techniques are also used, especially if the application is for a variable speed windmill.

There are conditions where two solutions are possible when selecting vectors. The specific choices usually affect harmonics content and switching losses. You might not need to worry about this for the first implementation.

In real life, space vector modulation is not use as is. You need to add various compensation loops to take into account various imbalances and measurement errors in the real system that produce all kind of strange components in the "pure" computation model.

Good luck and play safe.
