| In this paper, the analysis and design of three igniters based on a LC series network is presented. The proposed igniters have larger elevation capacity and smaller size than a typical LC series resonant network, because LC series networks include one transformer or one autotransformer, respectively. The proposed igniters are adequate for high intensity discharge (HID) lamp ignition and recommended for electronic ballasts that fed HID lamps with square waves, because they need no extra semiconductor elements. The igniters were evaluated with an electronic ballast that feeds a 70W HID halogen lamp with low frequency square waveforms, after which acoustic resonances were eliminated. Experimental results of the igniters with selected electronic ballast are presented.
