碩士 / 國立高雄第一科技大學 / 機械與自動化工程所 / 98 / This thesis aims at the investigation on implement of the power converter for ocean current generation system. In this system, a prime mover is used to drive the water flowing within a constructed water tank so as to simulate the behavior of ocean current. The flowing water can further drive a permanent synchronous generator for generating power. When the generator is operated, the characteristics of the generator will be further obtained. A converter can be designed in accordance with the characteristics.
In this thesis, the power converter is substantially a half-bridge resonant converter topology and the Petri net is used for analysis of the diving signal of the resonant converter. Additionally, a bidirectional power converter is further provided in the load stage of the proposed circuit system. Accordingly, when the ocean current velocity becomes slow, the power grid can further continuously provide extra power to the load via the bidirectional power converter.
Moreover, in this thesis, three factors including load value of the resonant converter, operation frequency of the resonant converter, and gear ratio will be selected to evaluate the optimal design so as to provide a preferred output power efficiency of the resonant converter by using Taguchi method and dual response surface method respectively.
