电源组件的电磁兼容技术

EMC Technology of Power Supply Subassembly

电源组件的电磁兼容技术包括硬软件设计。硬件设计须考虑电网噪声抑制、功率电路干扰抑制及印刷电路板设计,其中电网噪声抑制通过用压敏电阻抑制浪涌电压及采用切断噪声变压器抑制电网噪声得以完成。软件程序采用自顶向下,逐步求精的结构化设计方法,包括软件陷阱及程序死锁的解脱。

EMC technology of Power Supply Subassembly included the hardware and software design. Hardware design needed considering the net noise restriction, power circuit interference restriction and print circuit board design. Using the pressure-sensitive resistance to restrain the surge voltage and cutting the noise transformer to restrain the net noise accomplisheded the net noise restriction. The design method that is from the top-down and stepwise refinemen was adopted for software design, And it includes the disconnection of software trao and program dead lock.
