Ngaba uyawazi unobangela wokuvuza kwangoku kwiimfumba zokutshaja isithuthi sombane?

Ukutshaja isithuthi sombaneimfumba ukuvuza yangoku yahlulahlulwe ngokubanzi kwiindidi ezine, ezizezi: semiconductor component ukuvuza yangoku, amandla ukuvuza yangoku, capacitor kuvuza yangoku kunye nesihluzo ukuvuza yangoku.

1. Ukuvuza kwangoku kwamacandelo e-semiconductor

Umsinga omncinci kakhulu ohamba kwi-PN junction xa unqunyulwa.I-DS iya phambili, i-GS i-reverse biased, kwaye emva kokuba i-channel conductive ivuliwe, i-current iya kuhamba ukusuka ku-D ukuya kwi-S. Kodwa ngokwenene, ngenxa yobukho bee-electron zamahhala, ii-electron zamahhala zifakwe kwi-SIO2 kunye ne-N +, okubangela ukuvuza. yangoku yeDS.

2. Ukuvuza kwamandla ngoku

Ukuze kuncitshiswe ukuphazamiseka ekutshintsheni umbane wokutshintsha, ngokwemigangatho kazwelonke, kufuneka kunikwe isekethe yokucoca i-EMI.Ngenxa yobudlelwane besekethe ye-EMI, kukho umbane omncinci kumhlaba emva kokuba umbane wokutshintsha udibaniswe ne-mains, ekhoyo ngoku ukuvuza.Ukuba ayisekelwanga, igobolondo lekhompyuter liya kuba ne-voltage ye-110 volts emhlabeni, kwaye iya kuziva ingenangqondo xa uyichukumisa ngezandla zakho, kwaye iya kuchaphazela nomsebenzi wekhompyuter.

3. Ukuvuza kweCapacitor okwangoku

I-capacitor medium ayikwazi ukuba i-non-conductive;xa i-voltage ye-DC isetyenziswe kwi-capacitor, i-capacitor iya kuba nokuvuza kwangoku.Ukuba ukuvuza kwangoku kukhulu kakhulu, i-capacitor iya konakaliswa ngubushushu.Ukongeza kwi-electrolytic capacitors, ukuvuza kwangoku kwezinye ii-capacitors kuncinci kakhulu, ngoko ke iparamitha yokumelana ne-insulation isetyenziselwa ukumela ukusebenza kwabo kokugquma, ngelixa i-electrolytic capacitors inokuvuza okukhulu okwangoku, ngoko ke ukuvuza kwangoku kusetyenziselwa ukumela ukusebenza kwabo kokugquma (ngokulinganayo). kwisikhundla).Xa i-voltage esebenzayo ye-DC isetyenziswe kwi-capacitor, kuya kubonwa ukuba utshintsho lwangoku lokutshaja luqala ukuba lukhulu, kwaye luyancipha ngexesha.Xa ifikelela kwixabiso elithile lokugqibela, ifikelela kwisimo esizinzile ngokwentelekiso.Eli xabiso lokugqibela langoku libizwa ngokuba yi-leakage current.i=kcu(ua);apho k kukuvuza kwangoku okungaguqukiyo, iyunithi ngu μa(v:μf)

4. Isihluzi sokuvuza okwangoku

Ukuvuza kwangoku kwesihlunu samandla kuchazwa njenge: okwangoku ukusuka kwizindlu zokucoca ukuya nakwesiphi na isiphelo somgca ongenayo we-AC phantsi kwe-voltage ye-AC.Ukuba onke amazibuko okucoca afakwe ngokupheleleyo kwizindlu, ixabiso lokuvuza langoku lixhomekeke kumbane wokuvuza we-CY capacitor yemowudi eqhelekileyo, oko kukuthi, kuxhomekeke ikakhulu kumthamo weCY.Ngenxa yobungakanani bokuvuza kwangoku kwesihluzi, okubandakanya ukhuseleko lomntu, onke amazwe ehlabathi anemigangatho engqongqo yalo.Kubonelelo lwamandla lwe-220V/50Hz AC, ukuvuza kwangoku kwesihluzo sengxolo ngokuqhelekileyo kufuneka sibe ngaphantsi kwe-1mA.
