I would like to make a high current power supply, i have 2 x 3.3kw transformers rated at 110v, i would like to take the voltage down to 10-25v. is it possible to put a triac based dimmer type circuit on the primary ?
ultimately i would like to make it variable cv and cc, but there is nothing i can find on google that will allow me to construct something to utilize the full current capabilities which wont generate loads of heat. so at the moment just a variable rectified dc output will suffice. should i try to reduce the voltage just using one transformer ? or would it be alright to run one off the output of the other bringing the voltage down to an estimated 60v and go from there ?
any pointers and links most welcome,
