摘要

本論文旨在研製一整合雙向充放電器之永磁同步發電機驅動系統。使用微控制器Renesas RX62T完成所有控制，並以分切合整(D-Σ)電流控制法來做發電機輸出交流轉直流之換流器控制，雙向充放電器控制則採用T-S模糊控制法。發電機的三相電流由換流器轉成穩定的直流電輸出，再與雙向充放電器之高壓側端做連接，其中雙向充放電器用於電力調節使用，當發電機供至直流端負載能量有餘時，雙向充放電器操作在降壓模式；若發電機供至直流端負載能量不足時，雙向充放電器則操作在升壓模式。實測中以發電機在不同的轉速下，改變直流端負載功率，由發電機及雙向充放電器對直流鏈進行穩壓來進行驅動器系統性能驗證。

In this thesis, the permanent-magnet synchronous generator(PMSG) drive system integrated with bidirectional charger/discharger is designed and implemented. All control schemes of the inverter and converter are realized by microcontroller RX62T. The division-summation(D-Σ) current control is adopted for the AC/DC inverter at PMSG-end, and T-S Fuzzy control is applied to the bidirectional charger/discharger. The three-phase current of the PMSG is converted to a stable DC output and connected with the high voltage side of the bidirectional charger/discharger. The bidirectional charger/discharger is implemented to regulate the power flow. When the output power of PMSG is larger than the DC load, the bidirectional charger/discharger is operated at buck mode . On the contrary, the bidirectional charger/discharger is operated at boost mode. In experiments, the performance of the drive system is verified by changing the DC load at different PMSG speeds. The DC bus is regnlated by the PMSG and bidirectional charger/discharger.
