碩士 === 國立臺灣科技大學 === 電機工程系 === 100 === 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.
