摘　　要：本文提出了一种基于多片CPLD得多路SPWM波形的生成方法。详细的论述了SPWM波生成机理和试验系统硬件结构。实验结果表明、该方法确实可行。输出SPWM波形完美。接近正弦波。驱动系统良好。运行可靠、平稳。This article proposed a kind of production method based on the CPLD muhichannel SPWM profile, Described SPWM wave production mechanism and hardware architecture of the experimented system, detailly, The result of the test showed this method is truly feasible, the output of SPWM waveform is perfect, approached the sine wave, urged the system normally, operated reliably and steadily.

关 键 词：CPLD 多路SPWM 单元串联
