本論文著重於實作一具有高效率、寬範圍交流輸入、輸出19 V/10 A的電源供應器，該電源供應器是由無橋式功率因數修正器(Power Factor Corrector, PFC)和LLC串聯諧振轉換器所組成。而為了要節省傳統功率因數修正器輸入端上整流器的導通損失，經由前級無橋式電路架構的功率因數修正器來實現高轉換效率和高輸入功率因數。使用LLC同步整流串聯諧振轉換器當做後級直流-直流轉換器，一次側有零電壓切換且二次側有零電流切換和低整流損耗，可以實現高的整體效率。根據實測的驗證，在寬範圍的輸入電壓變化之下可實現良好的輸出穩壓。本論文所研製的電源供應器比傳統設計的轉換效率高了約1 %，經由加入過電壓保護和過電流保護設計，更可以滿足高可靠度的需求。

This thesis focuses on the implementation of a 19-V/10-A power supply with high efficiency and wide-range AC input voltage. The developed power supply consists of a bridgeless power factor corrector (PFC) and a LLC series resonant converter. By eliminating the conduction loss on input rectifier of the conventional PFC circuit, high efficiency performance and high input power factor can be achieved by the pre-stage power factor corrector converter with bridgeless circuit topology. The LLC series resonant converter with synchronous rectification is used as the post-stage DC-DC converter. Zero voltage switching at primary side and zero current switching and low rectification loss at secondary side can be realized to achieve high overall efficiency. According to the experimental verification, good output regulation can be achieved under wide-range input voltage variations. The developed power supply thus has a 1 % higher efficiency than the conventional design. High reliability requirement also can be satisfied by adding the over-voltage-protection (OVP) and over-current-protection (OCP) design.
