Abstract

Method and apparatus for controlling static charges on dielectric material by producing an ionized field and controlling the balance and magnitude of the directional conductivity of the ionized field. The directional conductivity characteristics are typically controlled by applying a DC bias of selected polarity and magnitude to a high voltage AC output which is applied to an ionizing member to produce the ionized field.
