基于FPGA平台的窄脉冲大电流LED频闪光源设计

Design of Narrow-pulse and High-current LED Strobe Light Based on FPGA Platform

针对高频信号的特点,利用FPGA,设计了一种窄脉宽、大电流的LED频闪光源。通过FPGA平台上的编程控制,实现了满足频闪光源控制时序要求的窄脉宽信号。最后,将窄脉宽信号进行电流放大,获得脉宽为ns级,电流最大可达30A的LED驱动脉冲信号。

In allusion to high frequency signals, design a narrow- pulse and high- current LED strobe light based on FPGA platform. By program- ming of the FPGA platform, generate the narrow - pulse signal that meet timing requirements of strobe light control. Finally, through the current amplification, we obtain the LED drive pulse signal which pulse width reaches ns level,and its current up to 30A.
