“…If the output stage of the power supply for plasma processing is not capable of igniting the plasma by itself, it is possible to use an auxiliary ignition module -e.g. a spark generator [41]. The process of plasma ignition becomes more complicated if the frequency of the applied voltage increases, as in the case of RF and VHF power supplies.…”

Integrated circuits, flat panel displays, solar panels, architectural glass, high resolution camera and many other products are landmarks of the 21 st century. All of these different everyday objects have one thing in common -they are manufactured using plasma processing techniques. The aim of this paper is to introduce this silent hero of modern industry, to a broader audience. An evaluation is made of common types of power converters within the scope of plasma processing applications, while the key requirements and future challenges for such power supplies are discussed.INDEX TERMS Plasma applications, plasma materials processing, power conversion, power electronics.

“…Todėl kibirštikliai gali būti naudojami įvairiose generatorių topologijose: Markso, Bloumlein ar kombinuotose grandinėse (Beyer, et al, 2004;Ponniran et al, 2016;Rose et al, 2017). Dielektrinio pramušimo raktai yra keičiami puslaidininkine technologija, nes yra neatsparūs korozijai, ir tokie raktai taip pat praranda savo valdymo/komutavimo savybes (Achour et al, 2018;Achour, et al, 2017). Kibirkštikliais grįstos sistemos turi ribotas impulsų parametrų valdymo galimybes, t. y. negalima valdyti trukmės ir/ar amplitudės, arba yra apribotas impulsų pasikartojimo dažnis.…”

“…According to many studies, 24,25 the transmembrane voltage needs to cause electroporation that is around 1 V high. This value can be used with cell size to calculate the minimum voltage that should be applied to the cuvette in order to get FIGURE 1 Structure of the pulse generator presented in Achour et al 19 electroporation. For instance, if we apply 4 kV to a 4-mm cuvette, then the electric field strength within the liquid will be 1 MV/m but the transmembrane voltage will depend on the cell diameter and also the charging time of the membrane capacitance.…”

“…To overcome those limitations, a hybrid-switching nanosecond pulse generator was proposed in Achour et al 19 It has a few nanoseconds rise time and also a simple structure, shown in Figure 1. It combines two types of switches, an IGBT and a spark gap.…”

In order to test the electroporation applied to mammalian cells (DU-145 human prostate cancer cell line), treated with short (30 ns) intense electric pulses, a new architecture of a pulse generator is proposed. It provides a quasirectangular output with nanosecond rise time and fully controlled repetition rate, which allows the control of the electric field dose applied to the cells.The system consists of a pulse generator with a high voltage gain and power efficiency, but it outputs exponential pulses. To improve that side, a pulse forming line (PFL) is used to get the final rectangular pulse. The whole device is designed using a multilayer printed circuit board (PCB) technology. That reduces the cost and increases the compactness of the generator. The output is connected to a special electroporation cuvette filled with special liquid. The impedance of such load is not well known, that is why some preliminary tests were carried out to identify the load of the generator. A number of simulations allowed to validate the design and to find out the influence of different parameters on its characteristics. Finally, a compact 4-kV generator was built and tested. The results are discussed and compared with those obtained from simulations.
