Hello people! I want to control dc-dc converter using digital controller.I want to give sensed output voltage to ADC. The output voltage(dc) will have ripples and many other harmonic components. My microprocessor is TMS320F28377S( 200MHz and ADC is 12 bit). I have some doubts.
- What should be my sampling frequency?
- Hhow should I design a low pass (to measure only dc component) and an antialiasing filter all in one?
