Re: [TCML] DC resonant charging: has anyone tried SCR's in thisdesign?
You could google for surplus 6500V thrysistors made by ABB, sometimes
they are sold on ebay for $25 each. I have two 6500V thrysistors in
series for total of 13kV that I plan to try out in the 20kV DC resonant
charging unit and see how it goes... See
http://www.richieburnett.co.uk/dcreschg.html about DC resonant charging,
but without SCR in design.
Yes richie's site has some good info as always on it. I already designed
mine with all the values, in's and outs.. just a matter of finding the
thanks for the suggestion, will have a look for them... was plugging some
numbers and I think the current pulse can only be 1KA tops, maybe last for
500uS tops, normally SCR's can take the peak rating for 3,000uS, so maybe I
do not need as large of current as I first thought. Even so the devices are
only 1,400volts 200A RMS, 3,000A Pk, around $40 each, to get to 20Kv.....
well thats a lot of SCR's!
