Silent Jack Posted February 23, 2011 Report Share Posted February 23, 2011 Looking at hooking up some high voltage capacitors in a series parallel configuration and was hoping some of the experienced folks here could share their recommendations for how best to connect them. I've had traces posited, as well as solid-core wires and bus bars. Quote Link to comment Share on other sites More sharing options...
Hero999 Posted February 24, 2011 Report Share Posted February 24, 2011 You really need to provide more information.It depends on the capacitance, voltage and rate of discharge. Quote Link to comment Share on other sites More sharing options...
Silent Jack Posted February 24, 2011 Author Report Share Posted February 24, 2011 Happy to; 6x 400V capacitors @ 470uF. Arranged 2x wide, by 3x deep. As rapid a discharge as possible once fully charged (Dumps to a solenoid). Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted February 24, 2011 Report Share Posted February 24, 2011 Solid copper wire solders good to component leads. High voltage on PCB's isn't good. Any sort of damage has to be evaulated for reuse. Quote Link to comment Share on other sites More sharing options...
Hero999 Posted February 25, 2011 Report Share Posted February 25, 2011 Just make the connections as short and as thick as possible.What are you using for back-EMF protection? Electrolytic capacitors don't like being charged in the reverse direction. Quote Link to comment Share on other sites More sharing options...

Hero999 Posted February 28, 2011 Report Share Posted February 28, 2011 I've never done it before so wouldn't be able to answer that question.What's the resistance and inductance of the coil? You should ensure the impedance of the capacitors and wiring is significantly less than that of the coil. Quote Link to comment Share on other sites More sharing options...
Silent Jack Posted February 28, 2011 Author Report Share Posted February 28, 2011 I could give you the physical specs of the coil, but I don't know its impedence. What is the best way to determine it? Quote Link to comment Share on other sites More sharing options...
Hero999 Posted February 28, 2011 Report Share Posted February 28, 2011 By using a formula which can be found using Google.http://www.google.co.uk/search?hl=en&client=opera&hs=4eV&rls=en&channel=suggest&q=inductance+calculation&aq=f&aqi=g7g-m3&aql=&oq= Quote Link to comment Share on other sites More sharing options...
