隨著電動車產業迅速發展，馬達驅動系統向高功率及高切頻發展。然而，高切頻雖能提升穩定性與響應速度，卻也導致開關損耗增加，尤其在高功率的情況下，對驅動器效率更是一大挑戰。因此，本論文採用輔助諧振換向極(Auxiliary Resonant Commutated Pole, ARCP)變頻器架構，透過柔性切換技術降低高切頻運作下的開關損耗，提升內藏式永磁同步馬達磁場導向控制(Field Oriented Control, FOC)的驅動系統效率。本論文著重於將ARCP架構實現於永磁同步馬達驅動系統，首先模擬ARCP單相等效電路的開關切換波形，並藉由模擬將ARCP與FOC進行結合，完成三相馬達驅動系統模擬。實測中，於硬體層面設計一套ARCP三相變頻器，並於軟體控制中結合FOC，應用於PMSM驅動系統中，且克服電路布局較為複雜所帶來的寄生參數影響，最後探討其在性能與系統效率方面之改善程度。

As the electrical vehicle industry continues to grow rapidly, motor driving system are trending toward higher power and higher switching frequencies. Although high switching frequency improves system stability and dynamic response, it also increases switching losses, which poses a significant challenge to inverter efficiency – especially in high-power applications. To address this issue, this thesis adopted the Auxiliary Resonant Commutated Pole (ARCP) inverter topology. By utilizing soft-switching techniques, switching losses at high frequencies were reduced, thereby enhancing the efficiency of an Interior Permanent Magnet Synchronous Motor (IPMSM) drive system under Field Oriented Control (FOC). This thesis focused on the implementation of the ARCP inverter in an IPMSM drive system. First, the switching waveforms of the single-phase equivalent circuit of the ARCP inverter were simulated, and the ARCP topology was integrated with FOC to complete the simulation of a three-phase motor drive system. In the experimental stage, a three-phase ARCP inverter was designed at the hardware level, and FOC was incorporated into the software control to realize a IPMSM drive system. The challenges caused by parasitic parameters resulting from the more complex circuit layout were successfully addressed. Finally, the improvements in performance and system efficiency were thoroughly investigated.
