Intelligent AC power electronic switch has a great advantage compared with traditional mechanical switch. There are high scientific researching and commercial values for developing a remote-controllable and re- liable and low-cost intelligent AC power electronic switch. Based on silicon-controlled rectifier (SCR), the intel- ligent AC power electronic switch is researched by internet and infrared control technology through mobile phone with excellent safety and humanization. The computer simulations and experimental tests are completed. The re- sults show that the design of the intelligent AC switch is feasible. Due to its safety and convenience, intelligent AC power electronic switch can replace the traditional mechanical switch and can be applied to smart home with the remote control of mobile phones. The circuit system is simple, reliable and easy to install with low cost and mass production.
