Hi,

I wonder if I can use uC instead of dsp to control space vector PWM? Does some of you used uC to control space vector PWM? Do you have code samples? Thanks in advance!

Best Regards,
ltg

I don't think you can do this with 8-bit micro, or you can choose one with hardware multiplier. Maybe PIC18 works.

I think it is possible by using the hardware cccp ports
they will give up to 19.4 khz as a 50 50 duty quite easily
but i think also perhasp two cores and a mux circuit could be used
to mux the pmw fromt he cccp
I was interested as i had never heard of this technique
so I found a picture

perhaps we will have some thoughts about it clearer
if I put a picture or 2 and also we can all add links to details
