Hi TI team,

Glad to chat with you,

Im designing 24VDC/180A rated charger design for EV vehicle. I have used UCC28951 PSFB controller based design. I need support design for the Bi-directional reverse polarity protection circuit for output side . Which means 24VDC/180A side or charging battery side.
