| 摘 要： | 分析了静态转换开关（STS）的无环流切换控制的工作原理。针对其中关键的电流状态检测问题，提出了一种根据晶闸管门极电压来检测晶闸管导通状态的方案。设计了1个TMS320LF2406控制的12A静态转换开关模块，描述了DSP中电压掉电时的控制时序，实际测试表明模块断电时间小于规定时间，提出的电流检测方法正确。

| Abstract: | The control theory for static transfer switch （STS） without circulation current is elahorated. The approach to detect SCR on-off state by measuring its gate voltage is proposed. Based on a DSP IC TMS320LF2406, a 12A static transfer switch is designed. And the flow chart in DSP is provided as the power supply lost. The experimental test shows the transfer time of this module is less than required time, and the detecting approach of SCR on-off state is available. |
