| 摘 要： | 利用大规模可编程控制器(Complex Programmable Logic Device)CPLD，针对静止补偿器(STATCOM)对触发脉冲信号的要求．设计一种基于CPLD的正弦脉宽调制(SPWM)数字触发电路。正弦调制波的产生采用查表法，但仅将1／4周期的正弦波数据存入CPLD的内部硬件所构造的ROM中减少了系统的硬件开销．并具有脉冲封锁等功能，仿真结果证明了本设计的正确性。

| Abstract: | This paper introduces the sinuous pulse width mod ul ation (SPWM) waveform generating, which is implemented in a Complex Programmable Logic Device (CPLD) chip, trigger pulse signal for static synchronous compensat or sinuous modulation waveform come form lookup table SPWM waveform data only in 1/4 sinuous cycle are required to be stored in ROM that is constructed with internal hardware resource of the CPLD The simulation result prove this design is correctly |
