adjustable expandable schematic
« on: February 05, 2012, 01:38:27 PM »
Hi all,
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.

Thanks to its simplicity and scalability, electromagnetic induction is still the technology of choice among many of the remaining companies in the wireless-charging arena.
