For high current applications I recommend Saligny Power.

This is made on aluminium substrate and can be mounted on a heatsink for applications up to 60A.

I have seen the HC Saligny, but even if it's a power amp, I draw only 2A per board.
Thank you for the shorter version, but I prefer something even shorter without fuses, LEDs, caps... as they are already in place.
The Saligny Standard is meant to replace PCB mounted linear bridges with zero effort. I want to do the very same but for my chassis mounted bridges.

Hi Tibi,
Does your new version of Saligny Power still requires the 10uF capacitor at Input?
Here are KiCad source files for Saligny Adaptor.
You may modify the layout as you wish, but if you use wires longer than 10cm, from this board to your capacitor bank, please keep a minimum 220nF MKP/FKP capacitor on the Saligny Adaptor board.
For continuous current higher than 10A, do not use block connectors, instead is better to solder in/out wires.

Saligny Power is made on aluminium substrate and make use of 220A mosfets.
In our tests the board reached 40Celsius at ~20A continuous load. Over this temperature I recommend the bridge to be mounted on a heatsink.

This is an example of poor engineering, bad application and understanding of synchronous rectifications.

Hi Tibi,
all your products have a requirement to have a capacitor after the bridge with a certain value.
the questions are:
1. what is the necessity for a capacitor?
2. why is it impossible/possible to use the LC input(saligny - L - C), and what processes will occur in this case?
3. Is it possible to use capacitors below the recommended values after the saligny bridge? if the current is guaranteed to be lower than the maximum allowable? take for example Saligny LC with a current of 0.5A( which has a maximum of 6A and 470uf minimum) can I use 100uf?

1. Because all Saligny synchronous rectifiers are self powered
2. Please reformulate. What is impossible/possible ?
3. I highly suggest to use minimum recommended values. For each Ampere I suggest to use al least 2000uF. Therefore for 0.5A you must have at least 1000uF.

AC -> Saligny LC -> L -> C (Choke input, where a choke goes right after the Saligny bridge)
Does it work?
Saligny rectifiers do not need snubber's before of after.
