资料介绍

对传统LED驱动电路特性进行概括性分析,然后结合其特点,从实用性和普遍适用性的角度出发,提出了一种基于恒流二极管驱动LED负载的新型简易照明方案,最后对该方案进行PF值补偿。该方案克服了开关电源电磁干扰严重,生产成本高昂等缺点,极大地消除LED的频闪问题,且能保证较高的转换效率的同时,拥有较好的PF值。该电路实用、生产简单,具有较高的生产推广价值。

This paper analyzes the features of the traditional LED driver circuit in brief. According to these characteristics and from the aspects of practicability and universal applicability, it proposes a solution to simplify LED illumination with driver based on CRD. In the end, this solution is adjusted with PF value. It overcomes the serious electromagnetic interference of switching power supply, the high cost of manufacture and some other disadvantages. The LED stroboscopic effect problem is greatly eliminated as well. At the same time, high conversion efficiency is ensured and the PF value is raised. The circuit is practical, easily manufactured and popularized with high commercial value.
