Hello, I´m lesrning something about coilguns ( in fact i did one but with a camera flash......) and now i want an upgrade, i have everything but the charger and this seems very good material, i also have some comparators as the lm393n or the lm311p
i did some succesfull experiments doing something turn off when a potentiometer lets the voltage rise to the 12v of reference from the battery, but in this circuit, my goal is to stop charging at arround 380v but i dont have an external supply of 380v to compare with, i think i should use a voltage divider but not sure how it works or where to place, also it would be nice a potentiometer in order to change the maximum voltage of the comparator, some help please?
