During the operation with a double-electrode Non-thermal Plasma (NTP) reactor with a Gliding Arc Discharge(GAD)there are many technical difficulties[1]. The reactor istheresistance energy receiver with a strongly non-linear characteristics. Whatis more,high voltages above 10kV are needed for pre-ionisation duringtheignitionprocess, whileafter ignition, the maintaining voltageis several times less. There is also a need to limit the current immediately for keeping non-thermal conditions in the reactor.A plasma reactor usedhere isbriefly described in thePolish patent [2]. In order to meet the requirements of the reactor’s supply, there is a strong suggestion to use a Switched-ModePower Supply(SMPS), the construction of which combines many interestingfeatures that are not commonly encountered.The push-pulltopology is not commonlyused in such applications. As a standard, it is used in inverters where the low input voltage is processed. The topology requires aprimary winding with special symmetry and the alternating current on the secondary side is obtained by switching the primary current between the two halves of the primary coilby delivering current to the centretap of the primary coil.In this case, the primary current is switched by IGBT transistors. The control can take place both from the microcontroller and the integrated analoguecontroller,whose advantage is resistance to radiated disturbances. The power supply can successfully achieve power above 1kW;however, when working with Micro Gliding Arc Plasma Reactor (MGAPR), such power ranges are not required[3]. In addition, the project is seen to have broad scientific perspectives of development. Improvements of ignition properties were obtained using achievementsresulting from work on switching overvoltages.The power supply hasapower and frequency regulation. Both of themcan work in controlfeedbackloops, but here in the experiment they are not used.The features mentioned are exceptional for the power supply and provide a wide range of possibilities insupplyingthe nonthermal plasmareactors. There are very wide adjustment properties in the range of 13-26 kHz and it has been proven to be exceptionally efficient in fulfilling its purposes.
