  7. Circuit refers

  8. PFC 被動功因:.利用電感、電容於電源端以便將領先或落後之相位做補償,線路架構上較簡單,但其存在體積大、重量重、輸出易因輸入電壓變動而閃爍不穩定。 主動功因:.一般利用市售之IC來達成功率因素修正功能,其原理乃將PFC.IC電路,至於橋式整流器及負載之間,使其電流隨整流後的電壓波型而做調整,其優點為輸出不因輸入電壓變動而改變,但奇線路架構上路較為複雜。 CEX740N, CEX10N4, CEX840N (400V/10A) (450V/10A) (500V/8A)

  9. PWM PWM(Pulse Width Modulation)把變流器的輸出電壓斬波成為脈衝,通過改變脈衝的寬度、數量或者分佈規則,以改變輸出電壓的數值和頻率的控制方法。 CEX02N6A,CEX02N6, CEX04N6, CEX09N6, CEX07N8 (600V/1.5A) (600V/2A) (600V/4A) (600V/9A) (800V7A)

  10. Synchronous Rectifier CEX6060R, CEX50N06, CEX70N06, (60V/60A) (60V/50A) (60V/70A) CEX9060R, CEX80N75, CEX60N10 (55V/100A) (75V/80A) (100V/60A)

  11. CET products

  12. MOSFET For Inverter

  13. AGENDA • Applications of inverter • Circuit board • Function block • Application circuit type • Mosfet & controller IC • MOSFET selection

  14. Applications of Inverter

  15. Circuit Board

  16. 在大型LCD Monitor的應用中,顯示面積愈大,代表需要的燈管愈多。 一支冷陰極管平均需要1000~1500V的驅動電壓,所以它屬於高電壓輸出,此時Inverter所扮演的角色除了減少耗電量之外,還要避免產生過熱的情形

  17. Function Block

  18. 以30吋的LCD TV計算,平均至少需要18支以上的燈管,20吋的LCD螢幕也至少需要12支以上的燈管o PDA、行動電話、Smart Phone等通訊與IA概念產品相繼問世後,對於顯示色彩、亮度等品質要求也愈來愈高,這些顯示都需要Backlight Inverter驅動光源

  19. Application circuit type-1

  20. Application circuit type-2

  21. Application circuit type-3

  22. Application circuit type-4

  23. Application circuit type

  24. MOSFET Selection

  25. MOSFET FOR Battery pack

  26. MOSFET For Battery pack

  27. AGENDA • Li-ion Battery pack • Application circuit type • Function Block • Summary • MOSFET Selection • Battery Protector

  28. Li-ion Battery pack

  29. Application circuit type

  30. Function Block CEM9926 / CEM9926A CEG8205 / CEG8205A CEM8206 / CEM8207

  31. Summary Battery pack 中一般皆採用保護回路 1>避免過充及過放電所產生的安全性問題 2>防止電池特性劣化 此回路一般由兩個mosfet 和一個保護IC 所構成 MOSFET 大都採SO-8 封裝,由於battery pack 體積要求輕薄 故以漸漸採用TSSP-O8,較高檔也有加ESD 保護o

  32. MOSFET Selection
