Ok here is my current design for a power supply for my project, here are the outputs I need:
5V able to drive up to 5A of current.
12V able to drive up to 1A of current.
-5V able to drive up to 1A of current.
As you see from my design, this is quite expensive for a power supply. The transformers alone are $30. Add the Regulators and its $40. Add the Misc components like the rectifiers and capacitors and we are talking $50 for this supply.
Are there any inefficiencies in this design? Any way to make this power supply cheaper and have the same capabilities? Any input would be appretiated.
