ABSTRACT:
An alternating current power supply for providing a high-voltage alternating current power output from a first low-voltage alternating current power source and a second low-voltage alternating current power source is disclosed. A first alternating current low-voltage power input is coupled to the first low-voltage alternating current power source, and a second alternating current low-voltage power input is coupled to the second low-voltage alternating current power source. A switch simultaneously couples the first low-voltage power input to a first output conductor and the second low-voltage power input to a second output conductor, thereby providing a high-voltage power output between the output conductors. A switch control activates the switch responsive to a phase difference, typically 180 degrees, between the first alternating current power source and the second alternating current power source. The power supply can include a voltage adjustment element to cause the switch control to activate the switch when a voltage difference between the first low-voltage input means and the second low-voltage input exceeds a predetermined minimum voltage.
