| Abstract: | 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. |
