Yuav ua li cas siv diodes hauv kev sib txuas lus hloov hwj huam hloov khoom?

Cov haujlwm tseem ceeb thiab cov kev siv ntawm diodes hauv kev sib txuas lus hloov hluav taws xob cov khoom siv
(1) Rectification Muaj nuj nqi
Daim Ntawv Thov Kev Siv: RECTEMATION yog ib qho ntawm cov ntawv thov yooj yim tshaj plaws ntawm diodes hauv kev sib txuas lus hloov hluav taws xob hloov khoom siv. Tom qab cov tswv yim ntawm AC fais fab, lub rectifier Circience Circience muaj cov diodes converts ac lub zog rau hauv DC lub zog. Cov Recification Recifications suav nrog ib nrab yoj rectification, puv plav rectification, thiab choj rectification. Choj rectifier Circuit Court yog dav siv hauv kev sib txuas lus hloov lub zog thiab cov hluav taws xob ua kom tiav rau cov dc voltage nrog lub pulsation me me.
Xaiv cov ntsiab lus: Hauv cov ntawv tso tawm, tsis ntsuas xws li thim rov qab wordage tam sim no, thiab tom ntej Voltage poob ntawm dodage yuav tsum tau txiav txim siab. Lub thim rov qab los nrog voltage yuav tsum loj dua lub tswv yim ncov ntawm kom ntseeg tau tias cov diode yuav tsis tawg thaum thim rov qab; Tus lej nruab nrab tam sim no yuav tsum tau raws li cov zis tam sim no yuav tsum tau ntawm lub zog hluav taws xob; Qhov me me rau pem hauv ntej ntawm voltage voltage poob, cov rectification efficiency, thiab tus me dua cov cua sov tiam ntawm lub zog hluav taws xob.
Xim: Cov cua sov dissipation teeb meem ntawm dodes tsis tuaj yeem tsis quav ntsej. Kev ua haujlwm ntev ntev tam sim no tuaj yeem ua rau cua sov loj heev ntawm diodes, cuam tshuam lawv cov kev ua tau zoo thiab kev ua haujlwm. Yog li ntawd, nyob rau hauv cov qauv tsim, lub voj voos yuav tsum tau muab tso tawm kom ntseeg tau tias qhov dej sov muaj cov dej sov muaj peev xwm ntxiv yog tias tsim nyog.
(2) Txuas ntxiv ua haujlwm
Daim Ntawv Thov Kev Siv: Hauv qhov chaw hloov hluav taws xob ntawm lub tshuab hloov khoom siv, qhov tsis sib xws yuav tsim lub zog electromotive rov qab, uas yuav ua rau lub tshuab hloov pauv. Cov freewheeling diode txuas nyob rau hauv parallel ntawm ob xaus ntawm inductor. Thaum lub tshuab hloov pauv tau muab tua, tus inductor cov ntaub ntawv ib lub voj los ntawm kev ywj pheej khaws cia hauv cov inductor thiab tiv thaiv tus hloov pauv hloov pauv.
Xaiv cov ntsiab lus tseem ceeb: cov dawb dowheeling diode yuav tsum tau kom cov yam ntxwv kom ceev ceev los txo qhov kev tshem ntawm lub raj. Nyob rau tib lub sijhawm, nws thim rov qab withsttalage yuav tsum muaj ntau dua qhov rov qab hluav taws xob hluav taws xob tau tsim los ntawm qhov chaw nruab nrab tam sim no yuav tsum muaj peev xwm tiv taus qhov ntau ntawm inductor tam sim no.
Saib xyuas: Tus luv dua rov qab lub sijhawm rov qab los ntawm cov freewheeling diode, qhov tsis tshua muaj kev cuam tshuam nws muaj nyob rau hauv kev ua haujlwm ntawm hloov fais fab fais fab. Yog li ntawd, thaum xaiv cov Diode dawb, yuav tsum muab rau cov qauv nrog lub sijhawm luv rov qab.
(3) Anti Rov Qab Txuas Zej Zog
Daim Ntawv Thov Kev Siv: Txhawm rau tiv thaiv cov neeg ua kom tsis txhob thim rov qab lub zog ntawm lub zog ntawm lub zog kev tiv thaiv kom ua tiav kev tiv thaiv anti. Thaum cov polarity ntawm lub zog muab tau, tus Diode coj los ua thiab lub zog muab khoom siv rau ib txwm muaj; Thaum cov polarity ntawm lub zog hluav taws xob yog thim rov qab, cov diode tau muab tua thiab lub zog hluav taws xob tsis tuaj yeem tso tawm.
Xaiv cov ntsiab lus: rau pem hauv ntej Voltage poob ntawm anti rov qab diode ntau li ntau tau los txo cov kev tshem tawm ntawm lub zog. Nyob rau tib lub sijhawm, nws rov qab withstandage yuav tsum muaj ntau dua cov tswv yim tshaj plaws ntawm lub zog hluav taws xob ntawm lub zog tam sim no yuav tsum tau ua rau cov khoom siv fais fab.
XIM: Vim tias qhov tseeb tias cov anti thim rov qab diode yog ib txwm nyob rau hauv ib lub xeev coj los ua, nws yuav tsim kom muaj qee yam kev siv fais fab. Yog li ntawd, ib qho diode nrog kev siv hluav taws xob qis, xws li Schottky Diode, yuav tsum tau xaiv.
(4) Kev Tiv Thaiv Clamp Kev Tiv Thaiv
Daim Ntawv Thov Kev Thov: Hauv kev sib txuas lus hloov cov hwj huam hloov pauv xws li hluav taws xob kev puas tsuaj thiab hluav taws xob yuav cuam tshuam rau cov hluav taws xob, uas yuav ua rau cov hluav taws xob ua rau hluav taws xob sab hauv lub zog hluav taws xob sab hauv lub hwj huam. Clam diodes tuaj yeem clamp overvoltage mus rau qib kev nyab xeeb, tiv thaiv cov kab txuas ntxiv ntawm kev puas tsuaj. Hom kev clamp
Cov ntsiab lus xaiv: Qhov tawg tawm ntawm cov hluav taws xob ntawm cov hluav taws xob ntawm cov kev ua haujlwm ntawm kev tiv thaiv Circuit Court thiab qhov kev tiv thaiv ntawm cov overvoltage; Lub ncauj lus rov qab tawg thiab clamping voltage ntawm TVs dodes yuav tsum tsim nyog ua kom paub raws sij hawm ua thiab voltage clamping nyob rau hauv ib qho kev nyab xeeb thaum muaj ntau tshwm sim.
Saib xyuas: Cov lus teb ceev ntawm lub clamp Dajode yuav tsum tau nrawm thiab tuaj yeem teb sai sai rau overvoltage. Nyob rau tib lub sijhawm, nws lub zog muaj peev xwm yuav tsum loj txaus kom nqus lub zog tsim los ntawm overvoltage.
