LT4320 based active rectifier
Hi Patrick,
Good point. It was my laziness and rendering takes long time (I had an old i3 laptop, slower than snail then) . So didnt do latest rendering.
I am attaching here correct renders for THT rectifier version.

regards
prasi

In This Post I tried to explain what I found to be why it doesn't work with center tapped secondary in constructing a split rail PSU.....it is because the bottom MOSFETs stay conductive most all the time during the AC cycle instead of turning on/off in sync with the top MOSFETs. I attempted a circuit trying to make it to work but it seems too much complexity would have to be involved in order to get it work properly under all possible conditions.

Hi Prasi -

You are very humble. I truly appreciate all the time and support you provide. It makes DIY projects much more approachable for beginners like myself.

With thanks!
Patrick
