BLPFC



now,I use PFC Bridgeless kit.

I looked at the module MATH_EMAVG instructions as follows:

1, it writes about the acquisition of AC signals, but why do we collect bus voltages?
2, how does it calculate the coefficient Multiplier? How does it come from 3332 in an example?What does this SAMPLE_NO mean?

  • It is just an averaging function. It can be used for a DC signal that has some ripple on top of it or it can be used for rectified AC voltage.

    For 4 half sine waves the number of samples will be 4x833 = 3332. So this averaging example is done over 4 half sine waves.
