i looking to build a power supply based around a large 3kva 24v transformer i have.(this can be re-wound to what ever is required) and a 180a bridge rectifier.
ive asked questions on other forums, and just seem to be going round in circles. ive read up on switching, scr control etc but got nowhere. so i have reigned myself to making a simple linear supply, with massive heatsinks, fans etc to dissipate the expected upto 3kw heat.
what i need is a schematic for a constant current and constant voltage 0v-24v (aprox) adjustable supply that i can just add a load of output transistors to to up my current load to above 70amps, and help with changing any of the passive components to get this working.
for example newbielink:http://www.electronics-lab.com/projects/power/001/index.html [nonactive]
any advice and leads would be greatly appreciated.
