電磁干擾(EMI)

輻射 (Radiation):經由空氣或其它介質發射

        出去的高頻電磁波

傳導 (Conduction):經由導線所傳播出去的

        低頻電磁波

emc electromagnetic compatility
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 path
EMI Couple Path

1. Direct radiation from source to receptor

2. Direct RF energy radiated from the AC mains or

signal/control cables of the receptor

3. RF energy radiated by AC mains, signal, or control cables

from source to receptor

4. RF energy conducted by common power supply lines or

signal/control cables

radiation emission test
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 test
  • 30MHz~1000GHz:Radiated emission test
