摘　　要：根据电动工具使用时的工况及安全需求,研制出用于电动工具的安全电源,该电源具有安全保护、调压调速和输出电压交、直流切换三重功能。实验测试结果为,当直流输出电压为60～230V时,最大漏电流为5.0μA。Based on the safe requirement and the condition of the use of the electric tools, the safe power is researched for the electric tools. The safe power has three kinds of functions： safety protection, voltage and speed adjustment and the switch between direct current and alternafing current. The testing result is that the biggest leaked electric current is 5.0μA when the output direct current power is between 60V and 230V.
