Photovoltaics (PV) yog ib txoj hauv kev tsim hluav taws xob lub zog los ntawm kev hloov lub hnub ci hluav taws xob mus rau qhov hluav taws xob ncaj qha hluav taws xob siv semiconductors uas nthuav tawm cov nyhuv photovoltaic. Lub tshuab hluav taws xob photovoltaic siv lub hnub ci vaj huam sib luag uas muaj ntau lub hnub ci uas muaj cov khoom siv photovoltaic.
Hais txog qhov no, cov khoom siv hauv lub xeev dab tsi hauv A C system tuaj yeem ua kom nrov thiab hloov hluav taws xob teeb liab?
Lub silicon tswj rectifier SCR, yog ib qho ntawm ntau lub zog semiconductor cov khoom siv nrog rau Triacs (Triode AC cov ), Diacs (Diode AC cov ) thiab UJT's (Unijunction Transistor) uas txhua tus muaj peev xwm ua tau zoo li nrawm heev solid state AC switches rau kev tswj loj AC voltages thiab tam sim no.
Tsis tas li, cov cuab yeej twg siv peb txheej semiconductor? Lub transistor yog tsim los ntawm kev siv peb txheej ntau dua li ob txheej siv hauv ib lub diode. Koj tuaj yeem tsim NPN lossis PNP sandwich. Lub transistor tuaj yeem ua raws li kev hloov pauv lossis lub suab nrov.
Tom qab ntawd, lo lus nug yog, uas yog ib qho dopant rau lub semiconductor uas ua hluav taws xob vim qhov kev txav ntawm cov nqi zoo?
Thallium
Dab tsi yog cov khoom ntawm semiconductors ua rau lawv muaj txiaj ntsig hauv cov khoom siv hluav taws xob?
Semiconductors paub tias muaj qee yam khoom tshwj xeeb uas ua rau lawv muaj txiaj ntsig zoo hauv cov khoom siv hluav taws xob. Semiconductors muaj ib tiv taus siab dua ib qho insulator tab sis tsawg dua tus neeg xyuas pib. Tsis tas li ntawd, cov khoom siv tam sim no ntawm semiconductor hloov pauv thaum lub impurity tsim nyog ntxiv rau nws.

Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Dab tsi ntawm cov hauv qab no yog qhov txiaj ntsig ntawm lub xeev cov khoom siv hluav taws xob sib nqus hard drive?
HDD tseem pheej yig dua SSD, tshwj xeeb tshaj yog rau cov tsav tshaj 1 TB. SSD tsis muaj qhov txav txav. Nws siv lub cim xeeb flash los khaws cov ntaub ntawv, uas muab kev ua tau zoo dua thiab kev ntseeg tau ntawm HDD. HDD muaj cov khoom txav thiab cov hlau nplaum sib nqus, txhais tau tias lawv siv ntau dua, lawv hnav sai dua thiab ua tsis tiav
Yuav ua li cas koj xaim lub tshuab hluav taws xob mus rau qhov ntsuas hluav taws xob?
Muaj peb cov xov hlau uas yuav tsum tau txuas mus rau qhov tseeb regulator davhlau ya nyob twg. Weld lub regulator mount rau lub tsheb laij teb ncej. Txuas lub regulator rau lub mount. Txuas lub roj teeb zoo cable hlau - feem ntau yog liab - rau tus tswj. Polarize lub generator los yog alternator los ntawm tus regulator
Koj siv lub ntsuas hluav taws xob ntsuas hluav taws xob li cas?
Txhawm rau siv lub ntsuas hluav taws xob, kov ib qho kev sojntsuam rau ib lub xaim lossis kev sib txuas thiab lwm qhov kev sojntsuam mus rau qhov sib txawv ntawm cov xaim lossis kev sib txuas
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
