Hey all, I'm and Aerospace undergrad at Cal Poly working on my senior project, which has turned out to be more of a EE project than anything else. Anyways, I'm building a capacitor bank for the firing of an electromagnetic rail gun. I'm attempting to make a PFN (pulse forming network) and capacitor ESR is KILLING me when it comes to buying a lot of cheap(ish) capacitors for my capacitor bank. Is there any way to practically eliminate ESR of a SINGLE capacitor. I am already connecting capacitors in series and parallel, and that can only decrease the ESR so much without buying a thousand of them. I would like to decrease ESR by orders of magnitude. Any thoughts?? One thought that I have had was connecting another resistor in parallel, that seems to increase current, but not the overall dampening of the system, as the PFN i'm working with is a slightly underdamped system, and the addition of capacitor ESR is causing it to dampen out to an unusable state. PS: I am simulating these circuits using matlab and simulink, and it seems to be a very reliable method, so please do not hesitate on just throwing an idea out there with no mathematical backing. I WILL just throw it into matlab and see what pops out. For any additional thoughts/questions about our railgun we are designing please email me at the email in my account here (email@example.com), please don't post generic rail gun stuff in this thread, i'd like it to stay on topic.
