Problem is I don't know much about control theory. First things first. It'll be fed by 24 Vdc and will output 120 Vrms. I have to control phase, frequency and amplitude. In this initial stage I'll use a trasnformer and an array of opamps to get the signal using SPWM. That way I'll get the phase and the frequency.
Problem is amplitude. I've read the amplitude of the 60Hz signal that you get after filtering is m_a*Vdc/2 where m_a is the division between the amplitude of the sine wave and the triangular wave you are comparing. I don't know wether to use a boost converter to get the Vdc real high and the just filter it, or get it to a somewhat good level and the use a transformer. Any questions, please feel free to make 'em. I would highly value suggestions.
