Help find TI example of isolated 3-phase IGBT gate drivers for 100v DC inverter bus

Other Parts Discussed in Thread: DESIGNDRIVE

Hello, I found from TI many reference designs for under 60v inverter DC power bus (such as using DRV83xx series) and also above 400v (like IDDK / DesignDrive) but nothing in between... We need a power range the same IDDK (22kw) to drive a BLDC motor but the bus voltage from a battery pack is around 100v .

If anybody knows TI reference design / demo of driving IGBT or MOSFETS with bus voltage covering the range of 64v to 110v DC for driving BLDC motor, please let me know.

Thanks

Hi Vlad,

Your post is being moved to the isolated controllers / motor controller applications forum for better support.

Hi Vlad,

You may want to take a look at this design for a 48 V automotive pump.

Thank you Nikolas , this design seems to be built modular and inverter stage drivers already allow up to 120v.

I have to make research in how many changes have to be done to so dramatically increase voltage from 48v to our current design' 84v (definitely more than just swapping two digits around :) Probably buck converter ....

Thanks again

Vlad
