three-phase four-wire (four leg) inverters

[Drouilhet]

Has anyone created any cRIO FPGA code for three-phase four-wire (four leg) inverters that they'd be willing to share?  Is there any in the NI code library?  I've searched through the master library of examples and haven't found anything, but maybe I'm not looking in the right place.

Thanks,

Steve

Here are a two new reports from the National Renewable Energy Lab (NREL) on numerous types of converter controls implemented with NI CompactRIO and Semikron including 4-leg inverter with zero-voltage switching (ZVS), isolated DC-to-DC (dual active bridge bidirectional DC-to-DC converter) with zero-voltage switching (ZVS), buck boost, solar MPPT, …

Hi,

4leg inverter output voltage control with Repetitive Control can be download from the PED-board website: www.ped-board.com

Go to download section.

Software is designed for the PED-Board but it can be definitely used for the cRIO.

AL3,

It is not clear which file in your download section contains the code you are referring to.  Please specify.

Thanks,

Hi Steve,

I apologize, wrong info. 4leg inverter Repetitive Control project is in the PROJECTS folder: SUPPORT -> PROJECTS.
