  • RE: TPSF12C3QEVM: Choosing the correct chip component values (UPS)

    Hi Omar, There are a couple of issues here - (1) the grid-side choke is super low, complicating stability, and (2) the switching frequency is very low at 18kHz, which will likely cause a large CM voltage disturbance at the filter midnode and saturation…
