As the developing of electronics industry , the power supply in electronic devices developed from linear power supply to smps ( switching mode power supply ) . the smps takes more and more important role in electronic industry , and is applied in many field , such as communication , computer , automation , military , industry , agriculture , etc 隨著電子行業(yè)的不斷發(fā)展,電子設(shè)備中的電源由最初的線形電源發(fā)展到開關(guān)電源。開關(guān)電源在電子行業(yè)中扮演著越來越重要的角色,應(yīng)用在通訊、計算機、自動化、軍事、工業(yè)、農(nóng)業(yè)等各個領(lǐng)域。
To show the applicability of the proposed algorithm for engineering problems , the thesis computed the radiated electromagnetic field of a switched mode power supply , with special attention on the analysis of the emi in the electronic control circuit . different numerical results and two valuable guidelines are drawn 從而以實際高頻開關(guān)電源為工程背景,通過對高頻開關(guān)電源產(chǎn)生的輻射電磁場的分析,重點計算了該開關(guān)電源控制回路處的主要電磁干擾,得出了相應(yīng)的數(shù)值計算結(jié)果和可供實用參照的結(jié)論。
