為了降低輸出大電流所造成的線路損耗及電流應力，本論文並聯兩組LLC-SRC 串聯諧振轉換器，搭配相移90°的機制，達到降低輸出電流漣波，提高效率的目的。由於傳統的交錯式LLC-SRC 串聯諧振轉換器會因為兩顆變壓器的誤差導致二次側輸出電流不均與輸出電流漣波抵銷功能變差。因此本論文利用了鐵芯整合的技術，將兩顆變壓器整合至同一個鐵芯裡面，並使用平板變壓器取代一般繞線架繞制的變壓器，藉此縮小兩組變壓器的誤差，使二次側輸出電流達到均流。

In order to reduce the line power dissipation and wire stress caused by high output current. This thesis connects two parallel LLC-SRC circuits with a 90° phase shift to eliminate the output current ripple for high circuit efficiency. However, the conventional interleaved LLC-SRC may cause unbalanced secondary output current and bad output current ripple cancellation due to the differences of two transformer. This thesis integrates two transformers into same core with core integrated technology. By replacing the usually applied winding transformer with planar transformer, the differences of two transformers would be reduced and balancing the secondary output current.
