本論文提出一具獨立調控之雙組輸出源直流-直流電源轉換器，藉由個別之回授控制來調控其輸出電壓，不會因各負載於彼此輕重載交錯變動時，造成電壓變動過大的問題外，由一次側開關之脈波寬度中加入一高頻脈波寬度來調控另一組輸出電壓，藉此以實現獨立調控之目的。最後，藉由理論推導、模擬及實作來驗證所提架構之可行性及有效性。

In this study, a control-independent dual outputs DC-DC power converter is proposed to stabilize individual desired output voltages, which are affected by each other due to variations in load as minimum as possible. Applying a high-frequency pulse width to the pulse width which is used to control one output voltage makes the other output voltage controllable, so as to achieve two outputs possessing individual controllers. Finally, via mathematical derivation, simulation and experimental results, the feasibility and effectiveness of the proposed topology can be verified.
