由於再生能源的輸出通常為較低電壓，故需要一升壓轉換器提升至高電壓以滿足負載需求或應用於併網型系統。因此已有許多種類的升壓直流-直流轉換器被提出。為進一步改善轉換器所需之效能，本論文提出一具柔切與較高升壓比之直流-直流轉換器。藉由加入輔助開關、諧振電感及諧振電容，所提之轉換器不需要操作於過大的責任週期即可達成較高之升壓比。本文之轉換器所有功率開關皆可達到零電壓導通，故可以減少功率開關的切換損失，此外輸出二極體可達到零電流截止，故可消除輸出二極體之逆向回復電流問題，因此轉換器之效率可獲得改善。本論文主電感操作於連續導通模式，故可降低輸入電流漣波。本論文實現一輸入電壓為直流90-130V、輸出電壓為直流400V且額定功率為800W之實體電路，並以模擬及實作結果驗證所提轉換器之理論與可行性。

Due to relatively lower output voltage of renewable energy sources, the converters with higher voltage gain are commonly needed to have a high-voltage DC bus to meet the demand requirements or to be used in grid-connected applications. Various high step-up DC-DC converters have thus been presented. To further improve the needed performance of low-ripple input current and high efficiency, a new soft-switching converter with resonant circuit is proposed in this thesis. The proposed converter can achieve higher voltage conversion ratio without extreme duty cycle used. In the proposed circuit, all the active switches can be turned on under zero-voltage-switching (ZVS) condition to reduce the switching losses. Besides, the output diode can be turned off under zero-current-switching (ZCS), so the reverse-recovery problem of the output diodes can be solved. The efficiency of the proposed converter is thus improved. The main inductor current is operated in continuous conduction mode (CCM) to alleviate input current ripple. To verify the effectiveness of the proposed converter, an 800W prototype circuit with input voltage of DC 90-130V and output voltage of DC 400V is implemented. Both simulation and experimental results are presented in the thesis.
