After a few days, I found a diagram of the converter model that can be found on ebay.
I would like to know if anyone would know how to modify this model to make it accept a higher input intensity. (ie move from 3A to 12A for example).
Which components are to be modified? which models to choose instead?
It is thus a call to the confirmed electricians and electronic engineers.
here is the link: http://www.nbglin.com/dc.htm
thank you!!
ps: at the bottom of the link in question, there is another link to documentation; in fact it is the detail of the components: their characteristics, their name, all that what
