Anybody hear ever try to build a 3 phase vfd ?

I am in the mood to build something that i could buy ready made cheaper.

I think that most people wanting to build 3 phase sources build the
rotary converters.

If you were going to build a 3 phase VFD I would suggest taking a look
at the Freescale DSP56F807 microcontroller. It has a great PWM generator
designed for stuff like this. I have used (underused?) the PWM generator
for DC motor drives, and it is really capable.

Good Luck,
