Abstract

Recently, a charge transport model allowing the description of electroluminescence in polyethylene films under AC stress has been developed. The fluid model incorporates bipolar charge injection/extraction, transport and recombination. The model has been very successful in explaining the time-dependence of EL under 50 Hz sinusoidal, triangular and square voltage waveforms. In this work we discuss experimental measurements and simulations using different frequencies of the sinusoidal stress, voltage amplitude and offset.
