傳統線性式電源供應器具有低輸出電壓雜訊與漣波之優點，普遍使用於精密量測儀器之電路架構，但因其體積及效率問題而限制高功率發展；切換式電源供應器具體積小與效率佳等特性在高功率應用場合逐漸替換線性式電源供應器。但控制策略與開關切換特性使其存有輸出切換雜訊，難以達到精密輸出之要求。
本論文旨在分析切換式電源輸出切換雜訊來源與其抑制方式，並提出一非隔離型雙向直流-直流電源轉換器。在寬範圍輸出下亦得以滿足全域零電壓切換的要求。在電路加入零電壓切換機制後，在不同輸入、輸出電壓與輸出功率下，輸出切換雜訊平均可以降低60%以上。

Conventional linear power supplies possess the advantages of low output voltage noise and ripple, they are commonly chosen to be the power conversion of precision measurement instruments. However, they are not applicable for high power applications due to their bulky volume and poor efficiency. Switching-mode power supplies are gradually replacing their linear counterparts in high power applications because of the advantage of small volume and high efficiency. However, the switching nature of these power supplies generates switching noise on output voltage, which makes it difficult to satisfy the requirements of high precision output.
This thesis aims to analyze the root and source of output switching noise and its suppression method for switching-mode power supply. Besides, a non-isolated bidirectional DC-DC converter with wide output range and zero voltage switching feature at wide load range as well. By virtue of zero voltage switching under different input/output voltage and output load, the generated switching noise is reduced over 60% in average.
