LED七彩莲花灯变色同步机制的抗电磁炉低频传导干扰实例

Case Analysis of Suppressing Conducted Interference From I nduction Cooker for Lotus Lamp's Color-change Synchronization

由LED七彩莲花灯的变色同步机制受大功率电磁炉低频传导干扰的案例为出发点,首先介绍莲花灯的基本原理及其变色同步机制,然后对出现的问题进行原因分析,最后运用低通滤波器抑制电磁炉的低频传导干扰,实现七彩莲花灯稳定的变色同步。

The color-change synchronization of LED colorful lotus lamp interfered by induction cooker in low frequency is taken as the starting point. Firstly, this paper introduces the basic principle of lotus lamp and its color-change synchronization. Secondly, it analyzes the problems in the case. Finally, low-pass filter is adopted to suppress low-frequency conducted interference in order to achieve lotus lamp's color-chang e synchronization.
