摘　　要：基于通过快速切换开关可以减少电压跌落对用户的影响,介绍了一种由晶闸管组成的快速切换装置。叙述了装置的组成结构和工作原理,描叙了切换装置的切换过程及电压检测的控制策略。最后,通过MATLAB仿真软件搭建了仿真电路模型,并搭建了试验样机。仿真及试验结果表明,切换装置切换过程为毫秒级,能满足一般敏感性负载的供电要求,验证了系统方案的可行性。The effect of voltage sag on the user was reduced by the fast switching switch. Based on the above consideration,this paper introduced a stand-by power fast switching device composed by thyristors and described its operating principle and structure constituent. The switching process of the switch device and the control strategy of voltage detection were described. Finally the paper presented a simulation model of circuits by using MATLAB and built an experimental prototype machine. The results of the simulation and experiments show that the switching process of this switch device is so fast that needs to be calculated by millisecond and the device can satisfy the electricity demand of general sensitive load. It verified the feasibility of the system solution.
