I have a standard AC-DC rectifier that gives me +24V, 12.5A power supply. Now, I've a problem... what's the simplest way to generate a negative voltage between the rails?
This may sound silly but I really thought I could just use the power supply as I would do to generate a positive voltage, but just run an extra wire to ground the end with the higher potential. Maybe I'm misunderstanding how the power supply works because it clearly didn't work.
I ran a search on "generating negative voltage" and saw a number of solutions involving ICs. But these have been proving quite expensive. I found it simple to invert the voltage, but maintaining a 12.5A output will be a problem. Will be great if someone can recommend me a solution! Thanks.
