    Hello to all!

    I am working on this project and I will ask for some suggestions. I was thinking to use current detector and voltage detector. Then I will pass the two signals to zero-cross detector and detect the time between the two pulses.

    But a college of mine told me to search for ICs for PF measurement, I found only ICs for active correction in SMPS. So the questions are: are there any ICs with that purpose (so I can remove the voltage and current detectors and use 1 of those) and is this method (with the V and A detectors) good?

    Can I use MCP3909 instead of voltage and current detectors for PF measurement?

    It looks like there is already a reference design doing exactly that.

    However, your project is a direct violation of this sites TOS so you'll have to ask elsewhere.
