Ideal diode bridge.

[davelectronic]

I was looking to have a go at building an ideal diode bridge, using the LT4320 and N channel mosfets. My idea was to bread board it first to get it laid out right. There is a couple of things I'm unsure of, i am going to use a dip package. I'm unsure on the mosfet rating, i know i want a working current of 15 Amps maximum, but typically 10 Amps continuous current. I was looking at the IRF540 mosfets, but not sure if these are suitable. Another thing I'm unsure of is cooling of the mosfets, and if heatsinks are required. My input voltage would be 14.80 Volts AC, and I'm using an LM2940CT-12 low drop out voltage regulator. Any advise on the ideal diode bridge appreciated.

Hiya. There are at least 2 huge threads on this subject, with all the questions answered. In my replies I have even included part #s and temp figures.
I have PCBs that I run to 25A cont / 30A ave without a heatsink, just 4+4oz copper. There's too much info to re-post, so try a search first. LT4320

Many thanks Digsys I will look it up.
