I will still have 16khz at the motor but each igbt will only be at 4khz,
well give me a email when you get a spare baord & chip  |
I have not seen the start of this discussion but it looks to me as though each of your IGBT will have to be rated for full motor current.....unless they are overlapping then the first that come on has to handle full current.
I am not seeing what the advantage would be?
