slide6

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。

(400V/10A) (450V/10A) (500V/8A)

slide7

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。
