Abstract

This paper reports about emerging techniques for the efficient drive of Dielectric Barrier Discharge (DBD) plasma light sources in pulsed operation mode. Besides a classification of pulse topologies, the novel Universal Sinusoidal Pulse topology, that provides high voltage amplification and high frequency operation, is presented. Transformer equipped and transformerless variations of the topology are presented. Experiments prove electrical efficiencies of more than 80%, while power measurements are cross-checked by thermal measurements. Additionally, frequency domain characteristics of the used DBD-lamp were analyzed and magnetic storage devices with distributed center gap are presented.
