Me and my friends have been building a project for a couple of months now and we got stuck on on something we dont have much experience with. We need to connect 4 charged capacitors into series in order to have a higher voltage than the supply, we have been using relays and a arduino nano to do this but recently we have been experiencing a lot of issues like contacts getting stuck or the relay stops responding to the Arduino.We already selected a mosfet(IRF840) that can be switched by arduino and can handle the voltage and current of our circuit. Now the problem we got stuck on is how we need to connect the mosfets and capacitors to get the results we want. We have tried a bunch of ways using simulators and couldn't find a proper way
