本篇論文研製具有高效率兩相交錯式串聯諧振式轉換器。此轉換器具有架構簡單、體積較小及高功率密度,且有效利用寄生元件達成零電壓切換技術(ZVS),以降低開關快速切換時,所造成的功率損耗,藉以達到高效率的目的。
此轉換器採用兩組相同半橋串聯諧振電路並聯,以開關控制訊號固定相移90o,藉以降低輸出電壓和電流之漣波,使得減小輸出電容值,並利用元件諧振現象,在開關上實現零電壓切換效果,其中諧振槽部分使用變壓器一次側漏電感做為諧振電感,有效節省成本並提高功率密度。
最後,本文經由理論計算,設計電路上各主要元件數值,並實際製作一400W實體電路,輸出規格為24V/16.7A,以驗證所提出之分析與設計,可得結果電流漣波明顯減少許多,而最高效率可達93.6%。


This thesis focuses on the study and implementation of a two-phase interleaved series resonant converter. The implemented topology is simple, light and high power density. Moreover, the parasitic components on switches and transformer are used to act as the resonant elements for zero-voltage-switching to reduce switching loss and improve efficiency.
In order to decrease output capacitance, two resonant converters are parallel-connected and two gate drive signals of switches are interleaved by 90o to reduce output voltage and current ripple. The resonant phenomenon achieves the desired zero-voltage-switching on switches. A suitable air gap on transformer is designed for deciding the required leakage inductance to replace the resonant inductor so that cost can be down and power density can be increased.
Finally, operation and analysis of the resonant converter are illustrated. A 400W power supply is implemented to confirm the feasibility of the analysis and design.
