本文提出一個新型整合型三相交錯式耦合電感，在每一相都可獲得相同感量的對稱新型耦合電感架構，利用鐵心整合的方式大幅減少電感體積，且透過磁通耦合降低電感鐵心損耗。文中提出磁阻模型用以解釋耦合感量與漏感量的比例，以及耦合係數α對於磁阻的影響。針對繞組部分，提出繞組部分分繞的方式，得到對稱的反向耦合繞組，並抵消直流磁通，達成高頻的應用下較小感量的需求。此外，為了減少鐵心損耗，移除鐵心結構的中心柱，提出新增體積增加漏感磁路的方式，避免工作週期大於66%時，會發生磁通的二Magnet以及實驗驗證在切換頻率1MHz、輸入電壓為50V和輸出功率為100W的條件下，新型整合型三相交錯式耦合電感得到較低的鐵心損耗。

This thesis proposed a three-phase interleaved boost converter with a novel integrated coupling inductor that can obtain same inductance from each phase. By core integration to reduce volume of inductor and decrease core loss via flux coupled. Expression ratio of coupling inductance and leakage inductance by reluctance model and effect of coupling coefficient in this thesis. For method of winding, this thesis also proposed part divided winding to obtain the symmetry inversely coupled winding which cancel dc flux and get lower inductance for high frequency application, too. In addition, take out the center leg to decrease core loss and added new magnetic path for increase leakage inductance to avoid secondary flux cancellation which caused inductor lost ability for limitation current. Finally, via magnetic simulation which called Magnet and test under condition of switching frequency 1MHz, 50V input voltage and 100W output watts to verify the three-phase interleaved boost converter with a novel integrated coupling inductor can get lower core loss.
