一种基于电压斩波和电流软启动CCR LED电源设计
Design of CCR LED power based on voltage chopping and soft current starting
摘要
Abstract
The constant current regulator (CCR) is general y utilized in domestic LED driver power with low or medium power. However, when AC voltage fluctuates, the LED current and power efficiency of this common circuit are unstable probably. The principle of the typical circuit was introduced, and the cause of the problems was analyzed. A CCR LED power driver based on voltage chopping and soft current starting was proposed. Both theoretical analysis and experimental data show that the improved scheme can effectively solve the two problems above.关键词
