摘要
从电路理论、失效模式分析、品质缺陷、电网环境方面精确分析阻容降压电源的起火原因,找到解决方案并进行市场验证。起火原因是电磁炉等电器产生的干扰通过电网加到阻容降压电源上的电阻,使电阻产生高温,引起火灾。在阻容降压电源上串联规格适当的电感,能降低加到电阻上的干扰功率。
The accurate analysis of the causes of fire about Resistance Capacitance Power Supply （RC Power Supply） is given from the circuit theory, failure mode analysis, quality defects and the grid environment ,to find the solution, and the market valida- tion is done. The cause of the file is that the interference of electromagnetic cooker and other appliances affects the resistance in the RC power supply by power grid, so that the resistance produces high temperature and fires. The series appropriate inductance in thc RC power supply can reduce the interference power which is applied to the resistance.
