Abstract :
In this paper, a new LED fluorescent driver compatible with a rapid-start ballast is proposed. Using a compensation circuit composed of passive elements, a new LED fluorescent driver having highly reliable and robust characteristics was developed. This driver can prevent the fire problem that arose in conventional LED fluorescent switching power supplies. The design principle and architecture of the proposed LED driver was explained, and its feasibility was confirmed by simulations and experiments.
