Abstract
The inventor has created several power supplied to eliminate or greatly reduce the ground loop problem. The inventor has discovered that the ground loop distortion is caused by the switching from positive to negative in alternating current. What the inventor has found is that just placing a diode across the two terminals of a power supply works to eliminate distortion and the ground loop problem. In the two simplest power supplies, the inventor has places a diode across the output from a half wave inverter. This helps to eliminate the ground loop problem and other distortion. The inventor also shows three other more complicated designs for power supply which include diodes and capacitors.
