Koj puas paub qhov ua rau cov dej xau hauv lub tsheb hluav taws xob them pawg?

Hluav taws xob tsheb themPile to tam sim no feem ntau muab faib ua plaub hom, xws li: semiconductor tivthaiv to tam sim no, lub zog to tam sim no, capacitor to tam sim no thiab lim dej tam sim no.

1. Cov dej ntws tam sim no ntawm cov khoom siv semiconductor

Cov tam sim no me me uas ntws los ntawm PN kev sib tshuam thaum nws raug txiav tawm.DS yog pem hauv ntej biased, GS rov qab biased, thiab tom qab lub conductive channel qhib, tam sim no yuav ntws los ntawm D mus rau S. Tab sis qhov tseeb, vim muaj cov dawb electrons, dawb electrons txuas nrog SIO2 thiab N +, ua rau to. tam sim no DS.

2. Fais fab kis tam sim no

Txhawm rau txo qhov cuam tshuam hauv kev hloov pauv hluav taws xob, raws li lub teb chaws tus qauv, EMI lim Circuit Court yuav tsum tau muab.Vim yog kev sib raug zoo ntawm EMI Circuit Court, muaj ib qho me me tam sim no rau hauv av tom qab lub zog hloov hluav taws xob txuas nrog lub mains, uas yog cov xau tam sim no.Yog tias nws tsis nyob hauv av, lub plhaub ntawm lub khoos phis tawj yuav muaj qhov hluav taws xob ntawm 110 volts rau hauv av, thiab nws yuav hnov ​​​​qab thaum koj kov nws nrog koj txhais tes, thiab nws tseem yuav cuam tshuam rau kev ua haujlwm ntawm lub computer.

3. Capacitor leakage tam sim no

Qhov nruab nrab capacitor tsis tuaj yeem ua tsis tau;Thaum ib tug DC voltage yog siv rau lub capacitor, lub capacitor yuav muaj ib tug to tam sim no.Yog tias cov dej xau loj dhau lawm, lub capacitor yuav raug puas los ntawm cua sov.Ntxiv nrog rau electrolytic capacitors, cov xau tam sim no ntawm lwm cov capacitors yog qhov tsawg heev, yog li cov rwb thaiv tsev tsis zoo siv los sawv cev lawv cov kev ua haujlwm rwb thaiv tsev, thaum electrolytic capacitors muaj cov xau loj tam sim no, yog li cov dej ntws tam sim no siv los sawv cev lawv cov kev ua haujlwm rwb thaiv tsev (feem ntau. rau peev).Thaum qhov ntsuas DC ua haujlwm voltage yog siv rau lub capacitor, nws yuav pom tias qhov kev hloov pauv ntawm cov nqi them tam sim no pib loj, thiab nws txo qis nrog lub sijhawm.Thaum nws ncav cuag tus nqi kawg, nws nce mus txog lub xeev ruaj khov.Qhov kawg tus nqi tam sim no yog hu ua leakage tam sim no.i=kcu(ua);qhov twg k yog qhov dej ntws tsis tu ncua, chav tsev yog μa (v: μf)

4. Lim tawm tam sim no

Lub xau tam sim no ntawm lub hwj chim lim tau txhais raws li: tam sim no los ntawm lub lim vaj tsev mus rau ib qho kawg ntawm AC cov kab nkag hauv qab qhov ntsuas AC voltage.Yog hais tias tag nrho cov chaw nres nkoj ntawm lub lim yog insulated kiag li ntawm lub tsev, tus nqi ntawm qhov to tam sim no mas nyob ntawm qhov to tam sim no ntawm hom hom capacitor CY, uas yog, nws tsuas yog nyob ntawm lub peev xwm ntawm CY.Vim qhov loj ntawm cov xau tam sim no ntawm lub lim, uas cuam tshuam txog kev nyab xeeb ntawm tus kheej, txhua lub teb chaws hauv ntiaj teb muaj cov qauv nruj rau nws.Rau 220V / 50Hz AC fais fab mov, qhov xau tam sim no ntawm lub suab nrov lim feem ntau yuav tsum tsawg dua 1mA.
