A corona charger can be programmed without physical adjustment to the charger, to give a plurality of desired characteristic plate current-to-potential curves so that one charger design can be used for a number of different charger formulations. The corona charger includes a conductive electrode and a corona wire between the electrode and the receiver. A variable duty cycle, pulsing voltage is applied to the electrode of same sign as the voltage applied to the corona wire, such that the corona charge produced by the wire is periodically accelerated by the electrode to the receiver.
