近年來，全球經濟與科技的快速發展，環境汙染及破壞的情形日漸劇增，各國因而開始發展綠色能源以代替化石能源，如：太陽能發電、風力發電、水力發電......等低汙染之可再生能源。本論文主要研製一具零電壓切換之隔離型雙向半橋式轉換器，本轉換器低壓側採用電流饋入式，高壓側採用電壓饋入式，除降低轉換器元件電壓電流應力之外，還能延長電池壽命，本轉換器有著元件數量較少、控制方法較簡單及不須額外輔助電路即能達成零電壓切換等優點。本轉換器擁有以下特點：(1)四功率開關工作在升壓模式及降壓模式時，皆能在負載20%至100%範圍內均具有零電壓切換；(2)透過高低壓側功率開關驅動訊號之間的相移角度變化而調整輸出電壓與輸出功率；(3)分析因電容電壓不平衡造成變壓器電流之影響，並分析在各工作區間中變壓器電流的變化，並使高低壓電容電壓能夠平衡，以提高轉換器效率及降低功率開關電流應力。本文完成最終研製出低壓側直流電壓40V〜48V、高壓側直流電壓200V、切換頻率100kHz、輸出功率500W之隔離型雙向直流轉換器，經實驗結果得出，轉換器在60%負載下最高效率可達92.3%

In recent years, the rapid development of the global economy and science and technology has caused environmental pollution and destruction. Countries have begun to develop green energy to replace fossil energy, For example: solar power, wind power, hydropower, etc., low pollution renewable energy. This thesis mainly Implementation of isolated bidirectional half-bridge DC/DC converter with zero voltage switching. The converter low-voltage side adopts current feeding type and the high-voltage side adopts voltage feeding type. In addition to reducing the voltage and current stress of the converter component, it can also extend battery life. The converter has the advantages of less component quantity, simple control method and zero voltage switching without additional auxiliary circuit. The converter has the following features: (1) When the four power switches operate in the boost mode and the buck mode, they can all have zero voltage switching within 20% to 90% of the full load; (2) Adjust the output voltage and output power through the phase shift angle change between the high and low voltage side power switch driving signals; (3) Analysis of the influence of transformer current due to unbalanced capacitor voltage, and analyzes the change of the transformer current in each working interval, and balances the high and low voltage capacitor voltages to improve the converter efficiency and reduce the power switch current stress. This thesis completes an isolated bidirectional 500W DC/DC converter with low-voltage side voltage of 40V~40V, high-voltage side voltage of 200V, switching frequency of 100kHz. According to the experimental results, the converter has a maximum efficiency of 92.3% at 60% full load.
