本文研製一部多階層切換式電容轉換器,不需使用任何電感元件,輸出電壓是藉由多組功率元件產生不同的切換狀態,使得轉換器能有多階層的輸出電壓,並且研究提高輸出電壓解析度的方法,使得輸出電壓的範圍更廣。文中探討了電路的基本架構,說明多階層切換式電容轉換器的操作原理。
本文以數位訊號處理器TMS320LF2407A為控制核心,並以混合型滑動控制器為控制策略,使多階層切換式電容轉換器能有快速的暫態響應,對於負載的變動也有良好的拒斥能力。最後與傳統的比例積分控制器作比較,實驗結果說明本文所提出的方法具有優於比例積分器的性能。
The thesis proposes a novel multi-level switched capacitor converter. This converter does not require any inductive element. By adjusting the switching states of the power devices, an adjustable multi-level output-voltage of the converter can be obtained. In this thesis, a new method to improve the resolution of the output-voltage is proposed. As a result, the output-voltage range can be extended. The structure and operating principle are discussed here.
A digital signal processor, TMS320LF2407A, is used as a control center. In addition, a hybrid sliding-mode controller is implemented to achieve fast transient responses and good load disturbance responses. Finally, the comparison between using the proposed controller and using the PI controller is provided. Experimental results show that the proposed method has better performance than the PI controller.
