頻率調變抑制電磁干擾之研究

Frequency Modulation Technique for EMI Suppression

指導教授 : 陳秋麟

摘要


本論文主要是探討利用頻率調變的技術,在交換式電源供應器上的應用,可對於電磁干擾產生抑制的作用。藉由數學的推導證明以及MATLAB數值分析軟體模擬頻率調變在頻帶上的影響。 最後實際作一個頻率調變的返馳式電源供應器作為實驗。根據實驗的結果,頻率調變技術可抑制電磁干擾。

In this thesis, the frequency modulation (FM) techniques for electromagnetic interference (EMI) suppression in switching mode power supply (SMPS) are studied. Effect of frequency modulation on frequency domain can be simulated by mathematical analysis and MATLAB. Finally, frequency modulation flyback SMPS is designed for experiment. According to the result of the experiment, Effect of FM technique can be used to reduce EMI emissions.
