Hi, I have a small capacitor start and run motor that I would like to run with variable speed. I am therefore trying to find an authoritative paper on programming an ATXMEGA chip to give me the required output to drive a commercial 3 phase bridge power chip. There is plently of explanation on SVPWM to generate 3 phase, but I cannot find a paper that gives the vector maths and switching sequence for 2 phase. All the papers I have read go quiet right at the crunch point. The example papers from Microchip are useful but do not give sufficient detail for my limited knowledge.
