| 摘要: |
| 利用大规模可编程控制器CPLD（Complex Programmable Logia Device)的高速，并行处理能力，设计了静止补偿器STATCOM（Static Synchronous Compensator)的脉冲发生器PWM（Pulse Width Modulation)。该脉冲发生器通过I／O口接受数字信号处理机DSP（Digital Signal Processor)写入的PWM脉冲宽度控制字，然后由CPLD定时产生PWM脉冲发生信号，CPLD在初始化后，可以独立于DSP进行触发脉冲信号的形成，通过仿真和实验结果，表明本PWM脉冲发生器精度高，稳定性好，具有较好的不对称控制能力和在线配置能力。 |

| Abstract: |
| The design of a CPLD(Complex Programmable Logic Device)-based PWM(Pulse Width Modulation)pulse generator for STATCOM(Static Synchronous Compensator)is presented.After the reception of PWM pattern parameters from a DSP(Digital Signal Processor)processor through its I /O port,CPLD periodically issues the trigger signal for generating the PWM pulse.After the initiation of CPLD,it may work independently without DSP intervention.The experimental results show that the CPLD-based PWM pulse generator is accurate and reliable with an excellent ability of non-symmetry control and online configuration. |
