本論文主要研究一具有高轉換功率的高頻直流轉交流電源轉換器,轉換器分為二部份,第一部份為DC/DC升壓轉換部分,採用推挽式轉換架構,將電瓶DC輸入電壓升壓到DC高壓直流,而DC升壓電路以開迴路不做穩壓回授控制,第二部分為DC/AC全橋轉換而將高壓直流轉成AC交流電輸出,依照所需要AC電壓與頻率及使用者開載的程度來調整全橋架構開關的DUTY大小以達到模擬市電標準規格。

升壓部份不採回授穩壓隨著輸入電壓高低及負載而浮動變化,可提高充電中使用的電源轉換器效率較低問題,相較於傳統回授穩壓的機種在整體轉換效率方面可約節省約5~10%的功率損耗,這一部份會以同樣機型但在DC/DC部份加了穩壓回授控制的另外一台機器實際加載來互相比較而得出結果與證實。

This paper focuses on the study of high-frequency DC to AC converter with high power conversion. The converter is divided into two parts. The first part realizes DC/DC boost conversion; the DC input voltage of battery is boosted to high voltage DC by virtue of push-pull type conversion architecture, while the open circuit of DC boost circuit is not subject to voltage stabilization feedback control. The second part realizes DC/AC full-bridge conversion; the high-voltage DC is converted into AC output, and the size of DUTY for the full-bridge architecture switch should be adjusted according to the required AC voltage, frequency and the degree of user's open load, in order to achieve the standard specifications for simulation of city electricity.
The voltage boost part does not adopt voltage stabilization feedback control. With the fluctuation in the level of input voltage and the load, the low efficiency of power converter used during charging can be enhanced. Compared with the machine of traditional voltage stabilization feedback, there is about 5-10% of the power loss to be saved in the overall conversion efficiency. This part will be compared with the actual loading by another same model of machine featuring DC/DC voltage stabilization feedback control, thereby gaining the results and being confirmed.
