Here's a few articles I've found very helpful from Microchip:

A couple of years ago I started on a design for an EV induction motor controller. I've learned a lot since then! Its not complete and I'm probably going to rip it up in favour of a surface mount design. It incorporates the micro, gate drive, voltage and current measurement, CAN interface and QE sensor input, if needed.
