资料介绍

分析了常见的双向可控硅(TRIAC)调光器应用在LED驱动上存在的问题。设计了一种利用普通PWM芯片结合外围电路搭建的可控硅非线性调光LED驱动电路,阐述了调光过程中电路的工作特性。实验结果表明,该驱动电路可实现0~100%平稳无闪烁调光。

Analysis was made to the existing familiar problems caused by the application of TRIAC dimmer in the light-emitting diode (LED) driver. A kind of thyristor nonlinear dimmable LED driver circuit was designed based on PWM integrated circuit with periphery circuits. The working characteristic of the circuit in the dimming process was expatiated. The result showed that the driver can realize smooth dimming from zero to one hundred percent without flashing.
