Hello! This is my first post here and i am building a power supply by rectifying AC mains. The mains electricity 220vac will be connected to a 20A variac and then a bridge rectifier then a capacitor bank consisting of 8 1500uf 400v capacitors, giving around 12000uf in total. I am trying to use this to power a solenoid with around 15 A current. Do i need to add any current limiting resistor or inductor? Thanks in advance!
