  • How to make a Supercapacitor Charger Circuit

    May 29 2019 · The circuit is powered by a 12V adapter we then use a LM317 to regulate 5.5V to charge our capacitor. But this 5.5V will be provided to capacitor through a MOSFET acting as a switch. This switch will close only if the voltage of the capacitor has less than 4.86V as the capacitor gets charges and voltage increase the switch will open and prevent the battery from getting charged further.
