本論文主要為研究電源轉換器並聯使用時之電流分配控制，讓電源轉換器可以在維持特定輸出比例的條件下進行並聯運作。本文採用電源轉換器並聯技術中之自動主僕均流法為基礎架構，藉由進行各個電源轉換器之電流迴授訊號的處理，改變電源轉換器各自在並聯總輸出中所佔的比例，達到一般均流並聯平均分配以外的分配比例。本文採用三部降壓式轉換器之並聯模式，其額定輸出分別為兩部12V/3A、一部12V/1A輸出之電源轉換器。模擬及實驗結果顯示，本文所採用之方法確實可行。

A current distribution control of the paralleled DC/DC converters is proposed in this thesis. The object is to maintain a specified power output ratio for paralleled converters so that each converter is operating under its maximum capacity rating. The automatic master-slave approach is used as the basic control structure for paralleling converters. By modifying the current signal of the paralleled converters, the desired output power ratio is achieved. This approach is more flexible in controlling the power distribution compared with the regular current-sharing techniques. Simulation and experiment are conducted by paralleling two 12V/3A and one 12V/1A output Buck converters as one system to verify the feasibility of the proposed method. The experimental results show that the method used in this thesis can provide the expected function.
