The catalyst chamber includes aheat- and gas-insulated partition; heating elements fixed on HPHM catalytic elementsmade of metal HPHMs of the chamber; catalytic elements made of high-poroushoneycombed materials and fastenings for heating elements.The power supply unit (the impulse high voltage power source) is constructedaccording to the power-bridge transformer circuit. The basic inductive element, i.e.the transformer, operates in the transit mode and does not save any magnetic power.It operates in symmetrical mode at low excitation currents. Due to this, such atransformer has smaller dimensions with the same capacity; its calculations areeasier. Low excitation current means less quantity of power accumulated in theleakage inductance. Hence, its suppression does not require complex dampingcircuits and switching-over processes in the transformer are considerably “quieter”.The high-porous honeycombed material permeable for the medium being purifiedis used as a discharge electrode. It is connected to one pole of the power supply; theother pole is connected to the electroconductive plate on the opposite side of thedielectric. The channel length is restricted by the distance between the HPHM cells.The number of micro-discharges increases proportionally to the voltage growth. Thustheir density increases which results in more effective use of the surface and morepower in the discharge area. The gas flow that passes through the permeable HPHMelectrode is turbilized, interacting with the chaotic porous structure of the electrode516
