Hi, I am studying the digital implementation of HHC and I saw the PMP41006. However, I cannot understand how it obtains the VCR voltage from the schematic below. Can someone explain it to me?

Thanks!

Hi Yuanze,
VCR is sensed by integrating the primary current through the secondary of curent sense transformer (CT).
