高压固态软起动主要由进线接触器、高压可控硅串联阀组和旁路接触器组成，如图2-1所示。其中高压可控硅串联阀组是功率变换执行部件，由多只可控硅串并联组成，并辅以收、均压箝位电路，其在高压环境中的可靠性。当进线端得电后，通过控制可控硅的导通角以实现对交流三相电源进行斩波，控制输出电压的幅值。并在起动过程完成后将旁路接触器闭合，软起动器切换到旁路状态，同时关闭可控硅。 一般高压固态软起动厂家设计基本上遵循将电量信号采集、系统控制、故障处理、脉冲触发、电源等功能集成在一块电路板上，例如2011市场上推出的一款高压固态软起动，该装置采用DSP控制技术、电力电子技术、可控硅串并联及光纤触发技术对电动机进行控制和综合保护，与其它传统的起动方法相比较，其特有的智能控制方式，既可以方便准确的设置起动转矩、起动电流、起动时间、停机时间等参数，又可以与微机、PLC等进行联网控制。如此集成化的电路板设计及软件控制编程需要进行大量的科研投入以及研发周期的增长，其中电路板测试、软件测试、整机测试、老化测试、抗干扰等测试也需要占用较长时间周期。研发周期过长势必将导致新产品在市场的占有，另外新产品的稳定性及实用性也待市场的检验。
