Hello,
I am using a 12v step down that then outputs 2 USB 5v 2amp ports. I connect an HDMI 5v transmitter and a GoPro like a camera via USB 5v. I would like to put a capacitor in front of my 12v stepdown to ensure reliable power when the train is moving and sometimes may not have a solid connection to the tracks. I cannot seem to figure out what I need to do this. Looking for help on a simple capacitor backup to a 12volt system for a 1-3 second power loss. I have a Bridge Diode Rectifier before step down and I think I may need to add a Power Resistor and/or a Schottky diode. I am no electronics expert but I am learning... I just not understanding how to use capacitors as a momentary backup to this buck converter... Please, any help would be appreciated and I can share much more on what my situation is.
