摘　　要：介绍了在恒压供水系统中,一拖二控制和DSP控制的双路逆变电路的调速控制对2台水泵进行变频调速控制的方案,并对这两种方案进行了分析和比较,指出DSP控制的双路逆变电路的调速控制方案性能更好。This paper introduces two different frequency control schemes for two water pumps with the frequency control of the two- path contravariant circuit controlled by one- pull- two scheme and DSP scheme, makes analysis and comparison of the two schemes, and points out that the performance of the frequency control scheme of the two- path contravariant circuit controlled by DSP scheme is better.

关 键 词：恒压供水 变频调速 DSP控制 变频器
