More Information
Summary:Apparatus is disclosed for driving from a single AC power supply a plurality of corona chargers and includes a substantially constant-potential power supply and a circuit interconnecting said power supply to the plurality of corona chargers such that a substantially constant average current input is delivered to each of the corona chargers. The circuit includes a capacitor associated with each corona charger between the power supply and the corona charger such that the capacitors charge upon transition of the AC power source, and thereupon discharge through the chargers until the corona onset potential is reached. Upon reaching the onset potential, the corona current is quenched. The capacitors are selected such that quenching occurs after the transition within a time interval less than half the period of the AC power supply so that each capacitor regulates the current output of the associated corona charger.
