The invention is a device for generation of high voltage pulsed-periodic corona discharge using formation of short pulses of high voltage on the electrodes of the pulsed corona chamber. These devices can be used for cleaning of gaseous or liquid media under normal atmospheric conditions as well as under very humid conditions, including aerosols of conducting liquids.

The technical result is formation of high voltage pulses with extremely short rising time (up to 5-10 ns) with high pulse repetition frequency (up to 1000 - 2000 Hz).  This allows to reach maximal efficiency of the plasma chemical oxidation of detrimental impurities, and to increase the range of stable discharge operation in presence of droplets of water or other conductive liquids in the discharge chamber.

It is possible to reach this goal using device comprising a high voltage power supply with limited output current, discharge capacitor, un-triggered spark gap and pulsed corona discharge chamber with electrodes that are connected by inductor.  An anode of the spark gap is made as an array of conductive rods and a cathode is made as a plate with flat surface.
