摘要
根据高亮LED特点,结合可控硅的斩波原理,提出一种运用FLYBACK和DC-DC相结合的两级拓扑结构、采用MCU进行全数字控制的调光驱动方案,解决了应用可控硅调光器对LED进行调光以及驱动器对可控硅调光器的兼容性问题。实验表明,所设计的驱动器能很好地实现调光功能,具有良好的应用前景。
By analysing the characteristic of HBLED, the article proposed a solution by using all-digital control driver method simultaneously solved the problem of using SCR dimmer in LED dimming, and the designed driver using the method can be compatible with SCR dimmers in the market. The experiments validate the correctness and superiority of this all-digital control solution, it has a good application prospects.
