律源興業股份有限公司與技術學院 具主動式功率因數修正與全橋相移轉換之1KW全數位式電源之研製 計畫編號：AA045 計畫類別：(　　民國4年 6月 1日起至民國 5年5月31日 合作廠商：律源興業股份有限公司24頁█計畫執行相關圖片與說明 中 華 民 國　104 年 9　月 8　日 具主動式功率因數修正與全橋相移轉換之1KW全數位式電源之研製 研 究 摘 要 數位電源的優勢在：與類比電源相較成本降低；控制拓樸靈活性能力；在不增加成本的情況下實現增值功能數位。TI公司的UCD3138為核心，來實作1KW的交換式電源；於輸入高壓(HighSide)方面，將以1顆40Pin的UCD3138晶片，使用交錯式PFC方式，來完成90~264Vac昇壓至390VDC的電源拓撲架構；而於輸出低壓(Low Side)側，也以1顆40Pin的UCD3138作為LLC移相諧振全橋(LLC Full-bridge Phase-shift)的DC轉DC電源拓撲架構。其具體格規為： 連續輸出850W 輸入交流電壓：85VAC ~260 VAC，45~ 65Hz 輸出直流電壓： Vo1 =12V, Io1 = 29A Vo2 =3.3V, Io1 = 69A Vo3 =5V, Io1 = 23A 3. 系統內之輔助直流電源：120 – 400VDC 1次側接點1 = 7V@0.3A 1次側接點2 = 13V@0.15A 2次側接點1 = 7V@0.3A 2次側接點2= 17V@0.45A 4. 工作頻率，fsw = 100KHz 5. 最大輸出電壓，Vo=48VDC 6. 最大輸出功率，Po = 1KW 7. 電流之諧波失真率，THD 5% 律源興業股份有限公司主動提出願再以5年為期，長期投入研發產學資金，每年培育3位有興趣投入交換式電源軔體開發的同學。為開創藍海策略，律源公司早先於同業投入數位電源管理之研究開發，希望除能為公司開拓未來的黃金10年外，更盼能為台灣升級，替社會儲材而做出貢獻。 關鍵字：交換式電源、數位電源管理 Abstract Digital (Digitalized) power advantages: compared with analog power, smaller part of the whole table, lower cost; the flexibility of controlling topology circuit with capacity enhancement; at no additional cost to achieve added value with a variety of upgrades and price dip again, resulting in commercialization has blossomed into a shape. Owner of this plan will enter its third year in conjunction with partners, and sustainable development based on the CPU switched-mode power digital control. This plans will to TI company of UCD3138 for core, to real made 1KW of exchange type power; Yu entered high-pressure (HighSide) aspects, will to 1 star 40Pin of UCD3138 chip, using staggered type PFC way, to completed 90~264Vac boost to 390VDC of power topology schema; and Yu output low voltage (Low Side) side, also to 1 star 40Pin of UCD3138 as LLC moved phase resonant full bridge (LLC Full-bridge Phase-shift) DC-DC power supplies of topology. Specific rules for: 850W continuous output Input AC voltage: 85VAC ~260 VAC,45~ 65Hz DC output voltage Vo1 =12V, Io1 = 29A Vo2 =3.3V, Io1 = 69A Vo3 =5V, Io1 = 23A System of
