"3. If input varies, then adjust the duty cycle to maintain calculated output voltage constant."
With phase-angle control, your are adjusting power, not voltage! Couldn't you sample the output via a filter with a suitable time constant to give you a DC voltage proportional to the output power, then use that as your feedback signal in the normal manner? |
