技術說明

本發明係一種全橋諧振換向式單級高功因電力轉換裝置，其與電源和直流負載相連接，所述裝置的電路包括有第一儲能電感和第二儲能電感，所述第一儲能電感及第二儲能電感分別連接至同一全橋諧振換向式電路，所述全橋諧振換向式電路與該直流負載之間串聯一逆止二極體；本發明相較於現有兩級硬切式電力轉換裝置省去一級轉換器，效率可提升；利用雙電感分攤輸入轉換器之電流，儲放能電感不易飽和，可使用在較大功率之電路；諧振換向式電路使切換開關具有零電壓切換之功能，可減少開關上損失，提升電路效率。 The present invention is related to a Single Stage Full Bridge high power factor converter with Oscillated Commutation being connected between a power source and a load. The converter has a first inductor and a second inductor, the inductors are respectively connected to a full bridge commutation converting circuit. The full bridge commutation converting circuit is connected parallelly to an energy storing capacitor. The present invention not only integrals conventional two stages invertor as a signal stage one but further provides very high transforming efficiency. For instance, the two inductors share current loaded of the convertor, so the convertor may be able to be used as a high power transformer. Switches of the full bridge commutation converting circuit all switch under zero voltage, so switching lost of the full bridge inverting circuit is also been reduced.
