Hi I have dozens of surplus PC AT/ATX power supplies and I am in the need for a power supply for a project (audio amp) with a voltage greater than these psu can supply and I want to put some use for them, so I decided to build from scratch, and rewind the EE cores for the output needed.
Now I´m wondering if 2 or more transformers can be driven in parallel for greater output power or do I have to build separate psu´s and place the outputs in parallel.
Ok so if you can give me some insight as to some of these points I would greatly appreciated.
1. How can I use 2 or more EE cores for greater output power?
2. What topology is best for this project ?
3. Do I use single or separate set of driver and switch to drive all the transformers.?
4. what is the highest or recomended volts/amp ratio I can get from these cores.?
