I am working on a new project that will be mounted on my racing car. I have to make a power distribution module using e-fuse and high switch modules to control the various loads.
Exaggerating, they will flow (if all the outputs are active) maximum 90-100 A (oh yes a good current!).
On the PCB there will be two converters from 12 V to 5 V and from 12 V to 3.3 V (for the MCU). I thought of using switching since they are now at a good price. As input I thought I would use one of those screw connectors suitable for over 200 A (if I remember correctly it produces the redcube and they should be press-fit). Immediately after the input a nice power MOSFET that acts as a reverse battery protection.
Is it recommended to use bulk capacitors after the reverse battery protection? How do I calculate the capacitance I need?
