The introduction of T5 (High-efficiency) and T5 (High-output) fluorescent lamps has increased the types of commonly used tubular fluorescent lamps from 9 to 18. Since each type of lamp must be powered by a specific ballast design, ballast manufacturers have to design 18 types of ballasts to cover th.....

Transformers are used for energy and signal transfer and for providing electrical isolation. CityU researchers have developed a coreless PCB-based transformer that does not require a transformer core, thereby reducing production cost and simplifying the automated manufacturing of transformers. The i.....
