本論文旨在研製多組電源轉換器並聯均流系統，其特點在於所提系統具有溫度感測補償均流機制，均流控制方法為自動主僕式均流法。轉換器模組設置上之差異，使模組間散熱能力有所不同，當較難散熱之轉換器模組持續分擔整體系統功率，將可能使該模組故障損壞，故本文提出偵測模組之環境溫度藉以調控模組之均流命令，使溫升較嚴重之模組能減低負擔功率，而在轉換器模組無溫升差異下進行均流控制，使整體系統可靠度增加。最後實作兩組轉換器並聯，其單組轉換器模組輸出規格為48V/10A，單組模組採用兩級電路架構，前級為功因修正升壓型轉換器，後級為相移型全橋轉換器。經實驗驗證在無溫度差異情況下均流誤差可達2%以下，且在模組溫度差異下可調節轉換器模組之分擔能力。

This thesis focuses on the design and implementation of multimodule paralleled power converters with temperature compensated current sharing scheme, method used the automatic master slave current sharing. The cooling capacity in each of modules is different result from different situations when installed. The module having poor cooling capacity will break down faster than the others. For this reason, the current sharing control method by sensing the temperature of each module is proposed for improving the reliability of system. Finally, the AC/DC 48V/10A power converter module is implemented for verifying the two-module paralleling system. The power factor correction boost converter and the phase-shift full-bridge converter are proposed in the first and second stage respectively per module. According to the results of experiments, the current error between two modules could be controlled below 2%, and the load regulation along with variation of temperature could be verified.
