Abstract
An apparatus is provided that performs continuous cleaning of a surface of a grounded material which is coated with an organic substance. The apparatus includes a plurality of electrodes covered with a dielectric and disposed along the surface of the material. The electrodes are connected to a high-voltage generator using a MOS power transistor connected to a step up transformer to convert low-voltage pulses generated from a low-voltage power supply into high-voltage pulses. The apparatus is configured to provide a pulsed electric field wherein the maximum voltage of the positive pulses Uis greater than the arc-striking voltage U, and the maximum absolute value of the voltage of the negative pulses Uis less than the striking voltage U.
