NCL30001 CCM模式单级PFC大功率LED驱动电源的设计

Design of NCL30001 Single-stage PFC CCM mode of High Power LED Driver Power Supply

LED是未来照明的发展趋势,现阶段与传统光源相比LED相对较高的成本是制约其大规模使用的一个很重要的因素。因此LED对驱动电源提出了高功率因数、高效率、长寿命、小体积、低成本的要求。文中使用NCL30001设计了100W单级PFC大功率LED驱动电源在满足高功率因数、高效率、长寿命、小体积的情况下极大的降低了LED驱动电源的成本。并设计了样机给出了实验参数和结果。

The LED is the development trend of lighting and has a relatively high cost compared to traditional light sources at present, which restricts its massive use. The requirements such as the high power factor, small size, high efficiency, long lifetime, low-cost are necessary for LED driving power. A 100W single stage PFC high power LED driver power supply using the NCL30001 was designed to meet the high power factor, small size, high efficiency, long life case of greatly lowering the cost of LED drive power. Finally, a prototype was designed and results were given.
