開關電源電磁兼容測試發展動態

摘要：祥細討論了開關電源電磁兼容測試的測量儀器設備、測試場地；環境電平、30MHz～l000MHz的輻射和電源端傳導干擾電壓/電流等物理量的直接測試方法；還討論了開關電源電磁兼容的替代的測試方法。最后闡述了我國電磁兼容試驗技術的發展動態。 敘詞：開關電源，電磁兼容，試驗技術，發展動態 Abstract：Give a minute discussed the switch power supply electromagnetic compatibility (EMC) to permit the test's diagraph instrument the equipments, test the field the ground; The environment electricity is even,30 MHz ～l000MHz radiation carry the conduction interference of voltage/ current with power supply; the direct test method that measure of physics of etc. Still discussed the switch power supply EMC to permit of in lieu of test methods. Finally， expound our country the EMC permit to experiment　technique of developing developments .
