传统注塑成型过程要求变频器能迅速切换速度以满足系统所需压力和流量，而产生的冲击电流须通过增加变频器的容量来吸收。介绍一种同步控制器，可根据工艺信号提前改变变频器的输出，为其速度的变化提供缓冲时间，保护了变频器并使其容量与系统所需容量相匹配。较为详尽地阐述了同步控制器的组成及工作原理。实践证明：同步控制器运行稳定、可靠，有效地降低了冲击电流。

The traditional process of injection molding requires the frequency converter to quickly switch speed in order to meet the pressure and flow rate that the system needs,and the generated impulse current is absorbed through increasing the capacity of the frequency converter.A synchronous controller was introduced which could change the output of the frequency converter in advance ac-cording to the process signal,thus buffer time was provided for its speed changing,and the frequency converter was protected and its capacity was made match with the capacity that the system needs.The composition and working principle of the synchronous controller were illustrated in detail.Practice shows that operation of the synchronization controller is stable,reliable and it effectively reduces the impulse current.
