  • saturation : n. 1. 浸透，浸潤。2. 充滿；飽和。3. 【化學】飽和（狀態）。4. 飽和劑。5. 【物理學】磁性飽和。6. 【色】濃度，章度。7. 【商業】（市場的）飽和供應，足量供應。
  • coil : vt vi 卷，盤繞，（把…）盤[卷]成一圈 （up）。n 1 （一）卷，（一）盤，（一）圈。2 螺旋管，蛇管。3 ...
  1. The second, at the high frequency primary coil, when switch turn on with control signal ( the spwm pulse is modulated ), in the positive or negative semi - period of low frequency modulation signal, transformer coil with same direction voltage. the magnetic flux of transformer core will increase step by step. at the end, it leads to magnetic flux saturation

    二、在高頻變壓器原邊，當開關管接收控制信號脈沖列（經調制的spwm波列）導通時，在低頻調制信號的正半周或負半周內，施加在變壓器繞組上的是同一方向的電壓，變壓器磁芯中的磁通可能將級進地逐漸增加，導致磁芯飽和，造成磁偏或單向磁化，導致低頻電信號放大失真或由於很大的磁化電流而無法正常工作。
  2. Current transformers are nonreplaceable in the field of protection and measurement for decades, but the electromagnetic current transformers can not meet the development of the electric power system for the reasons of magnetic saturation, ferro resonance, little dynamic range, narrow service band and so on 。 with the popularization of microcompute, it will be irreversible to apply microcompute in the protection and measurement, the equipments do not need the current transformer with high power, so the rogowski coil can apply on the field of protection and measurement

    電流互感器在繼電保護和電流測量中的作用長期以來具有不可替代的地位，但電磁式電流互感器所固有的磁飽和、鐵磁諧振、動態范圍小、使用頻帶窄等都難以滿足電力系統發展的要求。隨著微機的普及，在繼電保護和測量中應用微機已是不可逆轉的潮流，設備已不再需要高功率輸出的電流互感器，因此可以選用rogowski線圈作為低電壓輸出要求的電流測量和繼電保護應用。
  3. Firstly, the thesis introduced a eoct scheme that supplied on a special coil. it utilized saturation of special coil to transform form 10a ~ 720a current of busbar to 8v ~ 40v voltage of inductions. after switched to direct current, it supplied the loads of sensor by dc - dc transformations, which is included two + 5v voltages with respective ground and a group of 12v voltage

    該供能方案利用特製線圈的飽和特性，將母線電流大致在10a ~ 720a的電流感應約為8v ~ 40v的電壓能量，利用整流橋將交流電變為直流電后，由dc - dc變換器件將其轉換為兩路不共地的+ 5v和一組12v電壓供給後端傳感頭。
