  • ansoftmaxwell入門及相關基礎操

    Ansoft公司的Maww2D/3D是一個功能強大、結果精確、易于使用的二維/三維電磁場有限元分析軟件。它包括電場、靜磁場、渦流場、瞬態場和溫度場分析模塊,可以用來分析電機、傳感器、變壓器、永磁設備、激勵器等電磁裝置的靜態、穩態、瞬態、正常工況和故障工況的特性。它所包含的自上而下執行的用戶界面、領先的自適應網格剖分技術及用戶定義材料庫等特點,使得它在易用性上遙遙領先。它具有高性能矩陣求解器和多CUP處理能力,提供了最快的求解速度。靜磁場求解器(Magnetostatic)用于分析由恒定電流、永磁體及外部激磁引起的磁場,是用于激勵器、傳感器、電機及永磁體等。該模塊可自動計算磁場力、轉矩、電感和儲能用于求解某些涉及到運動和任意波形的電壓、電流源激勵的設備,可獲得精確的預測性能特性。該模塊能同時求解磁場電路及運動等強耦合的方程,從而得到電機的相關運行性能●渦流場求解器(Eddy Current用于分析受渦流、集膚效應、鄰近效應影響的系統。它求解的頻率范圍可以從θ到數百兆赫茲,能夠自動計算損耗、鐵損、力、轉矩、電感與儲能。允許用戶設置多項可變設計量,如位置、形狀、源及頻率等。可自動計算數千種情況的物理問題分析,而整個過程不許用戶干預。在繪制曲線模型時,系統默認的是將封閉后的曲線自動生成面,如果用戶不想讓其自動生成面,可以在繪制曲線模型前,點擊菜單欄中的 Tools/Options/Modeler Options項更改繪圖設置。材料庫的管理更加方便和直觀,新版軟件的材料庫主要由兩類組成,一是系統自帶材料庫的2D和3D有限元計算常用材料庫除此外還有 RMxprt電機設計模塊用的電機材料庫。二是用戶材料庫,可以將常用的且系統材料庫中沒有的材料單獨輸岀成用戶材料庫,庫名稱可自行命名,在使用前須將用戶材料庫裝載進軟件中

  • COOLMOS全面認識

    Recently a new technology for high voltage Power MOSFETshas been introduced – the CoolMOS™ . Based on thenew device concept of charge compensation the RDS(on) areaproduct for e.g. 600V transistors has been reduced by afactor of 5. The devices show no bipolar current contributionlike the well known tail current observed during the turn-offphase of IGBTs. CoolMOS™ virtually combines the lowswitching losses of a MOSFET with the on-state losses of anIGBT.

  • Active Filters

    Power conversion by virtue of its basic role produces harmonics due to theslicing of either voltages or currents. To a large extent the pollution in theutility supply and the deterioration of the power quality has been generatedor created by non-linear converters. It is therefore ironic that power convertersshould now be used to clean up the pollution that they helped to create inthe first place.In a utility system, it is desirable to prevent harmonic currents (which resultin EMI and resonance problems) and limit reactive power flows (whichresult in transmission losses).Traditionally, shunt passive filters, comprised of tuned LC elements andcapacitor banks, were used to filter the harmonics and to compensate forreactive current due to non-linear loads. However, in practical applicationsthese methods have many disadvantages.
