Electronic ballast requires a high voltage igniter to start up the HID lamps. An improved parallel igniter is proposed in this paper. The basic mechanism of it has been analysed and design principle is developed. Based on this parallel igniter, the lamp series inductor can be optimized separately. This improves the performance of both the igniter and lamp inductor. The simulation and experimental...
In this paper, a simple and effective method to obtain the small signal model of discharge lamps by means of step response is presented. The lamp parameters measurement is improved by means of a circuit based on passive elements. This study describes the conditions that must fulfill the parameters extraction, as well as the additional information that provides the step response test. The stability...
Due to the energy-saving and environmentally friendly features, dimmable magnetic ballasts will be paid more attention in the future. This make a more accurate fluorescent lamp model at different dimming levels necessary at low operating frequency. This paper presents a new method that considers the effect of tube temperature at different dimming levels in the process of the analysis of the fluorescent...
