Application status.
Professor Sun said that the current ballast circuit is getting easier and simpler, mainly because of the cost reduction and the reduction of the number of components. The development of electronic ballasts is divided into an integrated, miniaturized phase (a single-chip microcomputer can be used to produce a low-cost and high-performance green energy-saving lighting system); a high-efficiency phase and a high-reliability phase. Finally, Professor Sun introduced us to several electronic ballasts, such as high-performance fluorescent electronic ballasts and high-efficiency HID electronic ballasts.
