Hi,
I am currently designing a power distribution board that will take 12V from an external power supply and distribute the voltage to 8 devices. Each of the device will consume 12A and also to two other devices with less current consumption. In my design I would like to add a common mode choke for noise reduction. However I can't seem to find any common mode chokes with a high enough current. My questions is 1. is it a common design feature to include a common mode choke at currents larger than 100A? I only managed to see one component but it was obsolete. 2. After some reading it might seem that an LC low pass filter might be suitable. Is this approach recommended or is there a better noise reduction method.
At the moment I am simply taking 12V and distributing it out via MOSFETS and gate drivers. There will be some hall-effects current sensing in my design as well. The loads are all digital boards. There won't be any sources of high noise like motors in the area.
Thank you in advance.
