Abstract

PURPOSE: To enhance discharge efficiency and prevent the occurrence of uneven charging by applying DC high voltage to a corona discharge electrode and AC voltage to shields.
CONSTITUTION: This comprises applying voltage to shields 2 from a power source 3 thereby increasing the potential frequencies around a discharge electrode 1 and increasing its discharge efficiency. Now, when the DC high voltage V1 is applied to the power source 3, the potential gradient around the electrode is proportional to (V0-V1)/l. (l; distance between the electrode 1 and shields 2, V0; voltage applied to the electrode 1). In this way the DC high voltage is applied to V0 and the polarities of V0 and V1 are made mutually opposite, whereby the absolute value of the potential gradient is increased and the generation of corona is accelerated. If in this case the AC voltage is applied to the power source 3, the coronas of the same polarity as that of the DC voltage to be applied to the electrode 1 generate more. Thereby, the discharge efficiency is improved.
