開(kāi)關(guān)電源電磁兼容性問(wèn)題研究

摘要：隨著開(kāi)關(guān)電源的廣泛應(yīng)用，其電磁兼容性問(wèn)題顯得越來(lái)越突出。本文從開(kāi)關(guān)電源的電路結(jié)構(gòu)入手，分析開(kāi)關(guān)電源的電磁兼容性問(wèn)題的由來(lái)，并提出解決思路。 敘詞：開(kāi)關(guān)電源 電磁兼容 電磁干擾 Abstract：Because the electromagnetic compatibility in the switching power supply has great effects on electronics equipment ,limitation for the extensive use of switching power supply .This paper analyzes causes of electromagnetic compatibility form the SMPS circuit structure, and put forward to solve train of thought.
