電磁干擾( EMI)

傳導 (Conduction) :經由導線所傳播出去的        低頻電磁波

輻射 (Radiation) :經由空氣或其它介質發射        出去的高頻電磁波

Page 3: CE EMC 指令  2004/108/EC          Electromagnetic Compatibility Directive

EMC  乃電磁相容 (Electromagnetic Compatility)

含蓋電磁干擾 EMI (Electromagnetic Interference) 和電磁耐受性 EMS (Electromagnetic Susceptibility) ; EMI 為電磁場伴隨著電壓﹑電流的作用而產生 , EMS 為產品在使用過程中不受周遭電磁環境影響的能力。

造成 EMC 的三要素干擾源 (Source of EMI) : 自然的﹑人為的干擾路徑 (Propagation Mode) : 傳導﹑輻射受害者 (Receivers) : 電視機﹑收音機﹑無線電話﹑飛機﹑醫療設備 ……等

EMC 問題的現象分類 :(1) 低頻傳導現象 (2) 低頻輻射現象 (3) 高頻傳導現象 (4) 高頻輻射現象 (5) 靜電放電現象 (6) 高空核爆效應

EMI Couple Path1. Direct radiation from source to receptor2. Direct RF energy radiated from the AC mains or signal/control cables of the receptor3. RF energy radiated by AC mains, signal, or control cables from source to receptor4. RF energy conducted by common power supply lines or signal/control cables

Radiation Emission Test

.量測待測物在一開放空間中運作時所發射出來的EMI 雜訊

.量測場地分 Chamber (Pre-test) 與 Opensite (Final test)兩種

.資訊類產品的量測範圍分為以下兩種150KHz~30MHz : Power line conducted emission test30MHz~1000GHz : Radiated emission test
