Thermally activated electrostatic charging method and system

摘要

An electrostatic charging system that incorporates a thermally activated glow discharge ion generating technique. An large AC potential is applied between a pair of spaced apart electrodes. A heater disposed near the electrode pair gap is selectively activated to heat the gases in the region of gap to induce ionization. A DC potential applied to a third electrode draws the ionized particles toward a dielectric material to place an electrostatic charge thereon.
