Estimation of the light output power and efficiency of a XeCl dielectric barrier discharge exciplex lamp using one dimensional drift-diffusion model for various voltage waveforms

A XeCl dielectric barrier discharge under applied pulsed and sinusoidal voltage waveforms is simulated using a one dimensional drift diffusion model. In both waveforms, the light output depends not only on the gas mixture composition but also on the electrical parameters of the voltage waveform such as the frequency, the duty ratio...ctc. At the same amplitude of the voltage and the frequency, the UV output efficiency of the pulsed voltage is higher than the one of sine voltage. These results obtained in this paper allow to find out an appropriate power supply mode for a DBD excilamp.
