I would like to generate two dual 3-phase sine wave signal with 2*pi/3 offset in the range from 12 Khz to 15 Khz. I read many docs but I still not have any idea about the dds choice : I believe there will be no perfect solution but which one can represent a commonly good practice ?
After I join a power stage to have +18 V, - 18 V with max current bias at 3 A. As result current and voltage _must be_ phase aligned.
Question : is it better to have a frequency in Mhz reduce to a Khz or directly work with Khz range ?
