技術說明

一種交錯式直流轉換裝置，包含一電感、一變壓電路、一平衡電容、一第一開關、一第二開關、一電壓箝制電路、一輸出電容，及一輸出電路。該變壓電路具有相互對應設置的一第一繞組、一第二繞組及一第三繞組。該電壓箝制電路分別電連接於該第一開關及該第二開關，並受控制以分別箝制該第一開關及第二開關之跨壓。該輸出電路切換地將該第三繞組的電壓或該平衡電容的電壓傳遞到該輸出電容以作為該輸出電壓。能大幅減少元件使用數量並降低電路體積與重量，並具有較高的轉換效率，且適用於高範圍輸出電壓。 The aim of this patten is to develop a step-up/step-down zero-voltage-switching interleaved DC-DC converter for the switching power supply. The interleaved converter is composed of two shunted elementary boost conversion units, including four switches, a three windings transformer and a small auxiliary inductor. Due to the inductor in series the input source, the duty ratio of two main switches can be controlled over 50% so that the voltage gain is higher than the turns ratio. The proposed converter, only applied a winding and a capacitor in series on secondary side, can be auto balanced the currents of the interleaved two phases without an additional current-sharing module. The leakage inductance problem of transformer is solved by the active clamped circuit that results the switches with the ZVS and synchronous property.
