摘要：A method and an apparatus for charging a dielectric layer electrostatically to apredetermined potential. An AC electrode is arranged at a distance from the dielectriclayer and connected to one output of an AC voltage generator. The AC voltagegenerator has the other output connected to an output of a DC voltage generator.Between the AC electrode and the dielectric layer there is a DC electrode which isconnected to the other output of the AC voltage generator. The dielectric layer rests ona counter-electrode which is connected to the other output of the DC voltage generatorand is at ground potential. Each of the electrodes can comprise one or a plurality ofmutually insulated single electrodes.
