| Summary: | 碩士 === 逢甲大學 === 電機工程學系 === 107 === A multi-input step-up/down DC-DC converter is proposed in this thesis. By adopting this circuit topology as well as the pulse-width-modulation (PWM) technique, the bi-directional power flow control can be realized. Compare to the traditional power converter, the proposed multi-input converter can save the number of components and the circuit cost.
Recently, different kinds of energy sources have been rapidly developed. However, due to the inconsistency characteristics of different energy sources, active current control methods are necessary. Therefore, the proposed multi-input converter is able to achieve the active current regulation of different sources as well as realize the bidirectional power flow control. Finally, both simulation and experimental results verify the performance and feasibility of the proposed multi-input converter.
