Dielectric barrier discharge (DBD) excimer lamps are efficient and environmentally friendly sources of ultraviolet (UV). One of the challenges for this technology to be massively adopted is the optimization and effective management of the overall lamp-supply system. Accordingly, a methodology to study the impact of the operating point over the performance and operation of a DBD UV excilamp is developed and experimentally validated. The DBD operating point is parametrically adjusted by means of the power supply current with three independent variables: intensity, frequency, and duty cycle. This methodology allows the determination of the optimal operating point for the particular excilamp under study. These supplying conditions will be later achieved by means of a dedicated electrical generator, which has to be especially designed according to these specifications. It is found that an increment in the current intensity has a positive impact on the lamp efficiency and also leads to the existence of more filamentary discharges. Also, a relation between the energy of the pulse supplied to the DBD and the reactor efficiency can be established. For certain levels of UV power, energy savings on the reactor higher than 50% are attained by proper selection of the operating point.Index Terms-Current control, dielectric barrier discharge (DBD), excimer lamp, ultraviolet (UV).

“…Electrical modeling is the modeling by constructing an electrical circuit to characterize the overall discharge behavior of the DBD. The electrical modeling can be used to predict the external quantities such as external current and voltage [13][14][15][16]. On the other hand, the physical modeling is based on theoretical model such as the ionization and fluid models.…”

In this work, a fluid model of helium glow discharge at atmospheric pressure in a dielectric barrier discharge configuration has been developed and the discharge was numerically simulated. The transport equations for charged and excited species are self-consistent coupled to the Poisson equation for the electrical field calculation. A finite difference method technique is adopted; a detailed numerical procedure modeling is given. The addition of some nitrogen impurities to the helium successfully reproduced the discharge evolution during the breakdown. The numerical results showed that the discharge has a structure similar to DC low-pressure glow discharges and confirms the establishment of the glow regime at atmospheric pressure under very adequate conditions. The profiles of physical and electrical discharge parameters knowing that, particle densities, electric field, drift velocity, voltages and discharge current are presented and analyzed. A detailed study was made of the effect of nitrogen impurities on the stability of the glow mode of the discharge, and on the evolution of its parameters.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…This simplified model gives an insight of the DBD electrical operation, and it has been successfully used for the analysis of different power supplies. For more precise representations, there are complex models including variable conductance models [24], partial discharges [25], and the memory effect [26]. In order to have an initial analysis of the studied power supply, this article will use the model presented in Fig.…”

Power estimation of a DBD device supplied by a current source converter is studied in this article, pointing out the prominent contribution of the transformer parasitic elements. The impact of the stray capacitance and magnetizing inductance is stated and an iterative method that estimates the electrical power and DBD waveforms is presented. Results show that the magnetizing inductance can enhance the electrical power without changing the current ratings of the converter and that the stray capacitance must be minimized. Moreover, the experimental results reveal the need for a better DBD model to properly estimate the power. In consequence, an improved model is proposed and validated using a DBD excimer lamp in a wide range of electrical operating conditions.
