近年來電路設計高頻化是電力電子技術發展的主流，隨著電路分析之商用套裝軟體發展漸趨成熟，善用此類軟體提高生產力亦為極重要之研究課題，然而習知之模擬軟體於磁性材料建模上，並未考慮於高頻操作下的能量損失，又因坊間磁性材料種類繁多，於模擬軟體資料庫無法提供各類磁性材料模型時，電路設計者須自行建立所需模型參數，故本論文探討之目標為磁性材料模型之參數推導與建置。

磁性材料在高頻操作下之能量損失可分為磁滯及渦流兩類損失，本論文中以JA模式推導磁滯曲線方程式，並使用習用之OrCAD PSpice電子電路模擬軟體為建模分析工具，採用ABM模型方式來建立JA模式與參數，並在JA模式中參酌渦流損失對磁滯曲線之影響，再以各類應用電路來驗證磁性元件於電力電子電路之操作原理及準確性；最後針對繞組之銅損分析，本論文以一階梯電路數學模式推導，並使用多階線性階梯式數學模式來逼近繞組之近接效應與集膚效應。

Circuit design operated at higher frequency has been the mainstream in recent technology development of power electronics. As commercial simulation tools being fully developed for circuit design and analysis, it has been the main topic of research for utilizing the software to enhance design productivities. Nevertheless, due to the unavailability of commercial magnetic materials models operated at high frequency with losses consideration and various materials availability in the market, it is the main objective of this thesis to provide circuit designers with the capabilities on establishing the magnetic materials models for advanced circuit analysis.

The main losses of magnetic materials operated at high frequency consist of hystersis losses and eddy current losses. In this study, Jiles and Atherton Model (JA model) have been adopted for modeling hystersis characteristic equations employed in OrCAD PSpice simulation packages. Based upon the Analog Behavior Model (ABM) technique adopted in the package, the effects of the eddy current losses on hystersis phenomenon has been incorporated into considerations. Furthermore, application circuits have been simulated for verifications of the theoretical operation principle and effectiveness of circuits that contain magnetic components. Finally, ladder-network models employed for treating copper windings losses have been established for further consideration of proximity and skin effects in the windings.
