I need some info on negative voltage power systems.
I ran into a very complicated power supply system that I had to install. This system was engineered by a guy that designed microwave systems and has alot of the components powered by a negative voltage.
The thing I could not understand is that the ground is just a reference....because of this we were some how able to connect pos 12 volt power onto this same "ground bus" as we did the 24volt negative.
The dc to ac converters in the system were powered by a negative voltage ( meaning neg power wire went to pos input on the converter)
Most of the system is powered by neg voltage...except the 12 volt side. The system does not have a negative ground, it just has a ground reference.
Does anyone have any ifo on negative voltage power supply systems?
