中文摘要 | 本文提出一種新的並合式變流器架構,利用分離的單極脈寬調變信號,分別觸發 並聯的絕緣閘雙極電晶體( IGBT ),將總功率損失分配於各個並聯的功率開關元件上,使 變流器能操作在較高的電流及切換頻率下。因此,本系統可以增加系統容量以及降低系統體 積。本文首先推導並合式變流器的穩態等效電路模型,進而作系統特性分析。文中應用電流 控制脈寬調變變流器( CCPI )技術,以了解各並聯情況下的總諧波失真因數,且為節省能 源與利於系統之測試, 提出以循環電流方式之自我負載箱的測試系統。 最後, 建立一個 500W 的硬體雛型,經由實測結果驗證本文所提並合式變流器理論的可行性。 |
英文摘要 | This thesis presents a novel inverter scheme with paralleled IGBTs. The division of unipolar PWM signals is used to trigger the paralleled IGBTs separately. The total power losses is shared by the paralleled IGBTs, and hence the inverter can operate at higher current and switching frequency. Therefore, the developed system can increase system capacity and reduce physical volume. In this thesis, the steady-state equivalent circuit model of high switching frequency inverter with paralleled IGBTs is derived first. Then the response and performance of the designed system are analyzed. Besides, the total power losses are deduced accurately to serve the specification of the total harmonic distortion of the output current. By way of the controller of Current-Controlled PWM Inverter (CCPI), for saving energy and convenience to test of the system, the self-load band by circulating method is proposed in this thesis. Finally, the accuracy and effectiveness of the proposed system have been demonstrated on a 500 watt's prototype. The results of the experimental test show that the feasibility of the proposed novel inverter. |
