This paper presents an analysis of the consequences of using a step-up transformer in the supply of a dielectric barrier discharge (DBD) excimer lamp. A simplified transformer model is used to analyze the effects of the different parasitic elements in the operation of a current mode power supply. Mathematical expressions are found for each element and experimental validation is performed. The design...
In Dielectric Barrier Discharges (DBDs), the control of the power transfer, from the low-voltage static converter to the high voltage DBD, is strongly affected by the parasitic capacitive effects of the step-up transformer. Minimizing these capacitances is of major importance and this paper aims to establish and validate analytical expressions in order to predict the values of the parasitic capacitances...
This paper presents the study of a series-resonant inverter for the supply of a dielectric barrier discharge (DBD) excimer lamp. Causal analysis, based on the fundamental properties of the load, is used to justify the choice of this topology. In order to correctly control the lamp power, the operating mode selected for this converter combines discontinuous current-mode and soft-commutation (ZCS),...
