<p>1. Device of electric current static supply of an electrofilter (10) having two electrodes, one connected to the positive polarity and the other to the negative polarity of the supply, in which the output of a static converter (12, 140, 180) is connected to the primary winding of a step-up transformer (46), the secondary winding of which is connected to said electrodes by means of a rectifier (52) to apply continuous high voltage impulses of predetermined duration to these last electrodes, characterized in that said static converter comprises an inverter (12, 140, 180) equipped with a regulation circuit (54, 174), having a device (58, 60) to measure the average value of the high voltage current which supplies the electrofilter and making the frequency (F) of said impulses vary and/or the supply voltage (E) of the inverter to maintain an optimum value of said high voltage current corresponding to a continuous high voltage reasonably constant between said electrodes.</p> |
