Creating a Controller for IGBT-Based Power Supply

[diarmaede]

Hi All,

I work for a company that builds lots of IGBT-based power stages.  Currently, I would like to use some of these power stages in creating test fixtures that are controlled by LabVIEW.  Specifically, at this moment, I am interested in creating a three-phase AC power supply with variable output frequency.  There will be other projects down the line with different requirements.

Have any of you ever built something similar and used LabVIEW to control it?  If you have, I would appreciate any information you would care to share.

Thanks!

I do not have experience with such a project, but you may find this useful: Testing Motor Controllers Using FPGA-Based High-Speed Hardware-in-the-Loop Simulators. You may also find some of the resources at this link helpful: Leading the Way in Automated Test.

what you are trying to do is very similar to dc brushless motor control.  there are several approaches to use but you might want to go right to space vector modulation, SVM.  if you are planning on incorporating power factor correction, it gets more interesting.  if you company already produces 3 phase supplies, you should be able to get algorithms there as well.

This is not a trivial topic. good luck.

Thanks to all.  This is good advice.  And, yes, I know this is not a trivial project, but it could be interesting.  As my father always used to say, "The enemy is boredom!"
