Muhiimadda diode-yada sawir-qaadista ee tamarta qoraxda

Isku dhafka labajibbaaran ee unugyada cadceedda, diode waa qalab aad u caadi ah, diode-ka caadiga ah ee la isticmaalo asal ahaan waa diode silikoon toosiye, xulashada qeexitaannada si loo badbaadiyo xuduudaha, si looga hortago burburka.Guud ahaan, danab-jabka ugu sarreeya ee rogaal-celinta iyo hadda ugu badan ee shaqaynaysa waa inay ka badan tahay 2 jeer tamarta ugu badan ee shaqaynaysa iyo hadda shaqaynaysa.Waxaa jira laba nooc oo waaweyn oo diode ah oo ku jira hababka sawir-qaadista.

Diode-ka ka hortagga dallacaadda gadaale (ka-hortagga soo-celinta hadda)

Mid ka mid ah shaqooyinka Diode ee ka hortagga ka-hortagga dallacaadda dambe (ka-hortagga dallacaadda gadaal) waa ka hortagga hadda ee unugyada qoraxda in loo rogo unugga qorraxda ama array-ga labajibbaaran marka unugga qoraxda ama array-ga labajibbaaran aysan dhalin koronto Kan labaad doorku waxa uu ku jiraa array batteriga, si looga hortago in hadda u dhexeeya laamaha array-ga rogan yahay.Tani waa sababta oo ah tamarta wax soo saarka ee laan kasta oo taxane ah ma noqon karto mid gebi ahaanba siman, had iyo jeer waxaa jira farqi u dhexeeya tamarta sare iyo hoose ee laan kasta, ama kororka wax soo saarka ee laanta ayaa hoos loo dhigaa sababtoo ah cilad ka mid ah laan, hadh. iwmDhacdadan waxa lagaga fogaan karaa in la isku xidho diodes-buuxinta dhabarka oo taxane ah oo laan kasta ah.

Maroorsan karo'sDiode-ka-hortaggaWaxay leedahay danab lagu qiimeeyay 1600V, danab go'doomin koronto ah oo ilaa 3100V ah oo udhaxeeya chip iyo substrate-ka, dhalada dhalada ah ee dhalada ah ee la iibiyay, sifooyin heerkul aad u fiican iyo awooda baaskiilka, iyo dioska silikoon carbide, marka loo eego isticmaalka tamarta diode caadiga ah ee ka badan 15 %Hadda lagu qiimeeyay ilaa 55 A. Haddii nidaamkaagu leeyahay qiimayn hadda ka badan 12A, diode-kan waxa lagula talinayaa inuu ilaaliyo qaybahaaga.

Bypass diode

Marka qaybo badan oo unug cadceeddu ay si taxane ah isugu xidhmaan si ay u sameeyaan laan ka mid ah unugga unugga ama array-ga unugga, hal (ama laba ama saddex) diodes ayaa loo baahan yahay in lagu xidho si barbar-dhac ah oo isbarbar-dhigga wax soo saarka togan iyo taban ee guddi kasta, diode this , kaas oo si isbarbar ah ugu xiran labada daraf ee Golaha, waxaa loo yaqaannaa diode wareeg ah.

Doorka diodes-ka-dhaafka ah waa in laga hortago in qayb ama qayb ka mid ah qayb ka mid ah xayndaabka labajibbaaran aan la hadhsan ama laga joojin koronto dhalin haddii ay dhacdo in ay cilladi dhacdo, taxanaha hadda ee qaybaha waxay dhaafaan qaybaha cilladaysan waxayna ku qulqulayaan diode iyada oo aan lahayn. saamaynaysa korontada ee qaybaha kale ee caadiga ah, iyadoo sidoo kale ka ilaalinaysa qaybaha la hareer maray eexda hore ama dhaawaca ay sabab u tahay."Saamaynta barta kulul”kululaynta.

Diodes Bypass waxaa guud ahaan si toos ah loogu rakibay sanduuqa isgoyska, iyadoo loo eegayo cabbirka awoodda qaybta iyo tirada baytariyada, rakibidda 1 ~ 3 diodes.

Diode-pass-pass looma baahna xaalad kasta, marka qaybaha la isticmaalo kaligood ama isbarbardhigga, muhiim ma aha in lagu xiro diode.Qaybo dhowr ah oo taxane ah iyo jawi shaqo oo wanaagsan, waxaad sidoo kale tixgelin kartaa isticmaalka diodes-ka gudubka.
