Bakr Posted September 13, 2004 Report Share Posted September 13, 2004 I want to charge a 32uF capacitor to 5Kvdc using 12V, 7AH battery within 10 seconds. would anybody tell me any practical example?. I have designed a flyback circuit which charges it in 21 seconds. But I could not reduce it further. I have attached the circuit file. Please help me what is wrong in the circuit. How can I improve it? Quote Link to comment Share on other sites More sharing options...
steven Posted September 13, 2004 Report Share Posted September 13, 2004 :)wheres the attached circuit file Quote Link to comment Share on other sites More sharing options...
steven Posted September 17, 2004 Report Share Posted September 17, 2004 :)bakr , email me a copy of your capacitor charger circuit, ill check it out , ive left a message for you, my email address is in it, if you are haveing problems trying to upload it to the forum Quote Link to comment Share on other sites More sharing options...
steven Posted September 19, 2004 Report Share Posted September 19, 2004 :)bakr ill be looking in to this but here are a few circuits, for you that involve high voltage capacitor chargeing take a look at these, they may give you some ideas to help, the first one is veichle and object electrification circuit theres to much pages to upload but here is some Quote Link to comment Share on other sites More sharing options...

steven Posted October 25, 2004 Report Share Posted October 25, 2004 :) hang in there bakr ive allready started the exsperiments and research stagers for high voltage capacitor chargeing and have posted the hand powerd high voltage photo flash capacitor, charger information , ive recently tried it with my flyback driver circuit powering a disc shaped flyback transformer with great results, and ill be putting it together as soon as i get the matierials to biuld a circuit box for it. ill be biulding and ignition coil type hv capacitor charger to , now the flyback transformer i used was disc shaped without the in biult high voltage trippler , so if i was to use one with the inbiult trippler ill have to do some more exsperiments with that as ill be haveing much higher voltage output and if it exceeds the voltage rateing of even a 15 kv capaciotr , even though i dont have any, it may blow them, so ill have to get hold of some higher voltage capacitors to try. on it the flyback type hv capacitor charger ive put to gether to exsperiment with charges the photo flash caps up in around 15 seconds somewhere so ill post the results as i get them and you can use anything out of it to reach your goal.

tavix Posted May 20, 2005 Report Share Posted May 20, 2005 ;D bakryou must increase the power of your fly-back circuit for faster charge. for this increase the inductor current before switch off. by doubling this current the pulse energy will rise 4 times than before (square of current rise).good luck.
