dc.description.abstract | 本篇論文主要在分析與研製具主動式功因校正器之非對稱半橋(asymmetrical half-bridge,AHB)LLC諧振型電源供應器。電源供應器的發展一直是朝向高效率、小體積、低成本、高切換頻率...等,而在眾多的切換式電源轉換器的拓樸中,負載參與諧振的非對稱半橋LLC電路架構,因其構造簡單、元件數目少、效率高、功率密度高而逐漸受到重視。諧振時透過諧振電容、變壓器本身的漏電感與激磁電感和負載端的變化,將諧振操作在適當的工作區間,有效的利用電晶體本身的寄生電容和寄生二極體達到零電壓與零電流切換,減少開關損耗和降低切換電流應力以提高效率。
然而,除了提高轉換器的效率,發展具主動式功因校正的電源供應器亦日趨重要,因此本文在LLC諧振式轉換器的前級使用以升壓型轉換器為架構的功因校正器,將功因值提升以達到良好的用電品質,最後實做一台輸出功率150W的非 對稱半橋LLC諧振式電源供應器,以實驗結果驗證理論分析。 | zh_TW |
dc.description.abstract | The thesis is to analyze and implement an asymmetrical half-bridge(AHB) LLC resonant converter with active power factor correction. High efficiency, small size, low cost, high switching frequency are always the main goals of designing power supplies. Among various topologies, the load-dependent asymmetrical half-bridge LLC resonant converter becomes more and more popular because of its simple structure, less components, high efficiency and high power density.
The converter utilizes a resonant capacitor, the leakage inductance and the magnetizing inductance of a transformer, and the variation of the load to make the converter resonant in a proper region. In this way, ZVS and ZCS can be achieved by the mutual interaction of the parasitic capacitance and the body diode of the power MOS. Therefore, the switching loss and the current stress of the switch is relieved and the efficiency of the converter can be enhanced. However, in addition to improve the efficiency of a converter, developing a converter with an active mode PFC pre-regulator is important nowadays. Therefore, the AHB LLC resonant converter proposed in the thesis utilizes a boost-basic PFC pre-regulator to achieve a high power factor for optimizing the use of power. A 150W AHB LLC resonant converter is implemented to verify the theoretical analysis. | en |
