Lub alternating tam sim no generated los ntawm lub tsheb generator yog hloov mus rau hauv ncaj qha tam sim no tom qab raug kho los ntawm lub rectifier, tab sis nws cov waveform tseem muaj kev hloov pauv tsis tu ncua, uas cuam tshuam ncaj qha rau qhov tseeb ntawm lub tsheb ignition; cov zis hluav taws xob tsis tuaj yeem khaws cia tsis tu ncua, ua rau lub zog sib txawv ntawm txhua qhov hluav taws xob hluav taws xob. Lub tsheb lub cav yog shaken, thiab muaj cov xwm txheej xws li iav hloov kev ntxhov siab, qeeb ceev nce, tsis ruaj tsis khov ceev, thiab kev ua haujlwm qis ntawm lub tsheb cua txias. Yog li ntawd, qhov kev ua tau zoo thiab kev pabcuam lub neej ntawm cov khoom siv hluav taws xob hauv lub nkoj tau txo qis heev; ua ke nrog kev laus ntawm lub voj voog ntawm cov neeg laus cov tsheb, qhov cuam tshuam ntawm kev tiv thaiv hluav taws xob ntau dua, qhov cuam tshuam ntawm lub tsheb tau dhau los ua pom tseeb. Lub luag haujlwm ntawm cov hluav taws xob rectifier yog los pab lub tsheb tshem tawm kev cuam tshuam kev cuam tshuam, ruaj khov cov zis hluav taws xob, txhim kho qhov muaj peev xwm tawm tam sim ntawm lub zog hluav taws xob, ua kom lub zog tso zis ntau ntxiv, ua kom cov lus teb throttle, txuas ntxiv roj teeb lub neej, txo lub sijhawm pib lub cav tsheb. , txhim kho ignition efficiency, thiab lwm yam., tshwj xeeb tshaj yog rau me me hloov tsheb, cov nyhuv yog pom tseeb dua.
Tam sim no ntawm lub semiconductor PN hlws ris yog loj thaum nws yog rau pem hauv ntej biased, thiab tam sim no me me thaum nws rov qab biased. Lub rectifier diode yog ib hom PN hlws ris diode uas siv cov unidirectional conductivity ntawm PN hlws ris hloov cov alternating tam sim no mus rau ib tug ncaj tam sim no. Feem ntau, cov khoom siv uas muaj peev xwm tam sim no tsawg dua 1 ampere hu ua rectifier diodes, thiab cov uas muaj peev xwm tam sim no ntau dua 1 ampere hu ua rectifiers. Feem ntau siv semiconductor rectifiers suav nrog silicon rectifiers thiab selenium rectifiers. Muaj ntau yam khoom specifications, nrog rau voltages xws li kaum tawm volts mus rau txhiab volts, thiab tam sim no los ntawm ob peb amperes mus rau ob peb txhiab amperes. Rectifiers yog dav siv nyob rau hauv ntau hom ntawm rectified fais fab mov.
Lub zog hluav taws xob hluav taws xob hluav taws xob siab xav kom lub rectifier muaj peev xwm loj tam sim no, siab tawg hluav taws xob, thiab kev ua haujlwm zoo thaum tshav kub kub dissipation. Txawm li cas los xij, cov cuab yeej no muaj qhov sib tshuam loj thiab qhov sib txuas loj loj, yog li kev khiav hauj lwm zaus tsawg heev, feem ntau qis dua kaum ntawm kilohertz. Cov khoom siv silicon muaj qhov sib txawv loj thiab cov thermal conductivity zoo, uas yog tsim los ua cov khoom siv hluav taws xob siab. Ib qho hluav taws xob hluav taws xob silicon feem ntau yog siv hauv high-voltage rectifiers. Nws yog tsim los ntawm ntau lub tshuab rectifier cores hauv series. Nws thim rov qab tiv thaiv hluav taws xob yog txiav txim siab los ntawm kev tiv thaiv hluav taws xob ntawm cov tub ntxhais thiab tus naj npawb ntawm cov raj txuas txuas. Qhov siab tshaj plaws tiv taus voltage tuaj yeem ncav cuag ntau pua txhiab. Volt. Yog hais tias lub high-frequency rectifier Circuit Court yog siv nyob rau hauv ib tug ntau zaus, thaum lub voj voog ntawm AC voltage yog sib npaug rau lub sij hawm rov qab los ntawm lub xeev mus rau off-state ntawm lub rectifier, lub rectifier yuav tsis rectifies lub siab- zaus voltage. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua haujlwm siab, txoj kev doping kub feem ntau yog siv hauv silicon rectifier kom luv lub neej ntawm cov neeg nqa khoom tsawg, yog li ua tiav lub hom phiaj ntawm kev txo lub sijhawm rov qab.
