Abstract

A method is disclosed for controlling the DC voltage of an electrostatic precipitator having electrodes energized by a preset DC voltage in which the preset DC voltage has pulses superimposed thereon. According to the method, the pulses are periodically turned off. Thereafter, the corona discharge current caused by the DC voltage is measured and compared against a preset value. Thereafter, the DC voltage is adjusted in dependence upon the measured corona discharge current by it being increased or decreased depending upon whether the discharge current is lower or higher than the preset value.
