| 摘 要： | 机场助航灯恒流调光器系统要求输出电压的波形总谐波含量小，稳压稳频精度高。本文提出了一种基于DDS技术的SPWM波形产生方法。通过DDS频率合成的数学模型，介绍了在助航灯恒流调光器系统中基于DDS理论在TMS320LF2407A上实现SPWM波形的原理和方法及利用LF2407A的EVA模块生成SPWM波形的简便性，并通过实验进行了验证，对机场助航灯新型调光器的设计具有重要的参考意义。

| Abstract: | The constant-current dimmer system in the airfield requires the output voltage waveform to have high precision and stabilization.In this paper,a new method for producing SPWM based on direct digital synthesis (DDS)is proposed.Based on the mathematic mode of DDS on TMS320LF2407A,we describe the way to generate SPWM waveform by DDS technology.The experimental results show that our method is feasible and of great value for the design of new light dimmer system in the airfield. |
