ABSTRACT:
A power supply adapted for use with a corona charger. The power supply includes a first DC power source providing an electrical potential above a predetermined reference potential, and a second DC power source providing an electrical potential below such predetermined reference potential. A main circuit having an output adapted to be connected to a corona charger, includes a switching circuit for selectively turning the first and second DC power sources on and off in a manner so as to provide a an electrical potential having an AC waveform output for the main circuit.
