| 摘 要： | 在详细阐述正弦脉宽调制算法的基础上,结合DDS技术,以Actel FPGA作为控制核心,通过自然采样法比较1个三角载波和3个相位差为1200的正弦波,利用Verilog HDL语言实现死区时间可调的SPWM全数字算法,并在Fushion StartKit开发板上实现SPWM全数字算法。通过逻辑分析仪和数字存储示波器得到了验证,为该技术进一步应用和推广提供了一个良好的开放平台。

| Abstract: | On the basis of explaining the SPWM algorithm, this paper combines with DDS technology, puts Actel FPGA as the controlling core,compares a triangular carrier with 3 sine wave with 120 ° phase, and achieves entire digital algorithm SPWM on de- velopment board of Fushion StartKit.broad. Through the logic analyzer and digital storage oscilloscope,this technology has been verified. This paper provides a good platform for, the application of technology to further promote. |
