基于DSP+CPLD的三电平脉宽调制整流器脉冲发生方法
Power System Technology(2010)
Abstract
分析三电平脉宽调制(pulse width modulation,PWM)整流器弃用中矢量的对称三区电压矢量脉宽调制策略,根据其控制脉冲的特点,提出了基于逻辑法的数字信号处理器(digital signal processor,DSP)+可编程逻辑器件(complex programmable logic device,CPLD)的脉冲发生新方法。DSP负责发送区域信息和6路基准脉冲,CPLD通过逻辑运算辅助DSP产生三电平整流器所需的12路控制脉冲。实验结果表明,该方法正确,且占用CPLD芯片资源少,方法简单、实用;整流器工作稳定,功率因数高,直流侧中点电位平衡特性好。
