碩士 === 國立臺南大學 === 電機工程學系碩博士班 === 107 === This thesis is aimed at researching a modular inverter circuit for micro-turbine power generation system. In the circuit the inverter are divided by basic and extended modules, in which basic module is used to perform power conversion required from micro-turbine generator while extended modules are designated for online redundant services. Through this design, it is not only beneficial to improve the reliability of energy production, but also owns high flexibility of capability extension. Furthermore, a current-sharing scheme as well as a modular inverter arrangement is developed for the achievement of uniform current dispatch of online inverter modules. The method proposed in this thesis was examined under various scenarios. The results help consolidate the feasibility and practicability of the approach for the applications considered.
