“…Durations and peak voltages and currents, for operating stages (a) and (b) presented in the previous section, are calculated using trigonometric analysis; using the symmetry of the waveforms, this information allows one to describe the whole period. Calculations are detailed in [21] and results are summarized in Table 1 below:…”

“…On this basis, an innovative transformerless pulsed-current source topology is proposed in Section 2, where the switches are directly connected to the DBD high voltage. This power supply directly controls the energy injected into the discharge during each period; the theoretical approach of this solution was the subject of a previous (2017) publication [21]. In the current paper, we propose a complete sizing of the power supply and we justify the choice of each component, notably the 10kV SiC MOSFETs [21] and diodes, as presented in Section 3.…”

At low pressure, cold plasmas are used for a wide range of applications such as coating, flow control, or microelectronics. Currently, this industry requires expensive vacuum systems which consume energy and time, and therefore it is very appealing to develop similar processes at atmospheric pressure. Under this condition, dielectric barrier discharge (DBD) is one of the best ways to obtain a cold plasma. The dielectric barriers naturally limit the current, and then the plasma temperature. Unfortunately, at atmospheric pressure the discharge ignition between the electrodes requires high voltage, which is generally obtained through a step-up transformer. The parasitic elements of this device exclude a smart control for the discharge. In order to overcome this default, we analyze the performance of a transformerless power supply developed with a recently released single-chip high-voltage semiconductor. The circuit uses only two high-voltage switches synthesized by means of the 10 kV SiC MOSFET (Metal Oxide Semiconductor Field Effect Transistor). The design and implementation of the electric converter are presented and validated with experiments carried out on UV excimer DBD lamps. Then, the performances of the 10 kV SiC switches are analyzed and the relevance of this device for DBD applications is discussed.

“…Most of them require a transformer to step up the voltage in order to achieve ignition. However, recent studies have shown that transformer parasitic elements greatly affect system behaviour [18][19][20]. One of the most relevant effects is produced by transformer equivalent capacitance.…”

This study is focused on studying a resonant current converter for the electrical supply of dielectric barrier discharge devices. To understand the impact of parasitic capacitances and incorporate them into the design of an optimised power supply, this approach theoretically analyses a boost-based resonant converter, considering switch capacitance and analysing the impact of the transformer turns ratio on the system's electrical efficiency. The theoretical loss analysis shows a considerable variation in efficiency for different transformer turns ratios (between 38 and 90%). At low turns ratios, most of the losses are caused by switching, whereas at high turns ratios, the conduction losses outweigh the switching losses. The impact of the transformer stray capacitance is analysed via simulation and the optimised converter is used for the experimental validation of the theoretical study.
