Analysing DBD plasma lamp intensity versus power consumption using a push-pull pulsed power supply

摘要

In this paper characteristic of a DBD (Dielectric Barrier Discharge) plasma lamp is investigated based on the lamp intensity and power consumption. A pulsed power supply with controllable parameters based on a push-pull converter is developed for lamp excitation at different voltage levels and repetition rate. The experimentations were conducted for 28 different operating points with the frequency range of 2 kHz to 15 kHz at output voltage levels of between 7.4 kVpp up to 13 kVpp. The obtained results show the feasibility of finding an optimum operation point due to nonlinear behaviour of the DBD lamp.
