Diyaarinta unugyada cadceedda: Diode-ka-hortagga Diode iyo Bypass Diode

Qaabka isku wareeg ee unugyada qoraxda, diode waa aalad aad caadi u ah.Diodes-yada caadiga ah ee la isticmaalo asal ahaan waa daloodhka toosiyaha silikoon.Markaad dooratid, ku dhaaf meel ka baxsan tilmaamaha si aad uga hortagto burburka burburka.Guud ahaan, danab-jabka ugu sarreeya ee dambe iyo wakhtiga ugu sarreeya ee shaqaynaya waa in uu ka badan yahay labanlaab tamarta ugu badan ee shaqaynaysa iyo hadda shaqaynaysa.Diodes inta badan waxay u qaybsantaa laba qaybood oo ka mid ah nidaamyada tamarta tamarta qoraxda.

1. Diode-ka-hortagga dib-u-celinta (Anti-Backflow).

Mid ka mid ah shaqooyinka kaDiode-ka-hortaggawaa in laga hortago in batteriga hadda ku jira moduleka unugyada cadceedda ama array square in loo rogo moduleka ama array square marka uusan dhalin koronto, taas oo aan kaliya isticmaalin tamarta, laakiin sidoo kale waxay keentaa moduleka ama shaxanka labajibbaaran kululaan ama xitaa waxyeelo soo gaarto;Shaqada labaad waa in laga hortago socodka hadda u dhexeeya laamaha array square ee batteriga array. Tani waa sababta oo ah danab wax soo saarka ee laan kasta oo taxane ah ma noqon karaan gabi ahaanba siman, had iyo jeer waxaa jira farqi u dhexeeya danab sare iyo hoose. laan kasta, ama koronto wax soo saarka ee laanta waa la dhimaa cilad ama hadh dartiis, iyo hadda laanta tamarta sare waxay u qulquli doontaa laanta hoose ee tamarta, ama xitaa kororka wax soo saarka ee wadarta labajibbaaran waa la dhimi doonaa.Dhacdadan waxa lagaga hortegi karaa in laan kasta lagu xidho diodes-ka dallacaadda lidka-reverse.
Nidaamka korantada ee madaxa-bannaan ee sawir-qaadista, qaar ka mid ah wareegyada kontoroolka sawir-qaadista ayaa lagu xiray diodes-ka-hortagga-celinta, taas oo ah, marka kontarooluhu uu leeyahay shaqada dallacaadda ee ka-hortagga, wax-soo-saarka qaybta uma baahna in lagu xiro diode.
Diode-ka-hortagga wuxuu leeyahay hoos u dhac hore oo danab ah, waxaana jiri doona isticmaalka koronto gaar ah marka si taxane ah loogu xiro wareegga.Dhibicda korantada ee diode toosiyaha silikoon guud ahaan loo isticmaalo waa qiyaastii 0.7V, tuubada awooda sare waxay gaari kartaa 1 ~ 20.3V, laakiin korantada adkeysigeeda iyo korontadu waa yar tahay, ku habboon codsiyada tamarta yar.

Diodes-ka-hortagga PV waxay u baahan yihiin inay yeeshaan sifooyinka soo socda:

1. Korontada sare: guud ahaan waxay u baahan tahay in ay dhaafto 1500V, sababtoo ah ugu badnaan sawir qaade ayaa gaari doona ama dhaafi doona 1000V.

2. Isticmaalka awoodda hooseeya, taas oo ah, iska caabbinta (xakamaynta gobolka waa sida ugu yar ee suurtogalka ah, badiyaa wax ka yar 0.8 ~ 0.9V): Maadaama nidaamka sawir-qaadista uu u baahan yahay inuu ilaaliyo waxtarka sare ee nidaamka oo dhan, awoodda Isticmaalka diode anti-reverse ee sanduuqa isku-darka waa inuu ahaadaa mid yar intii suurtagal ah.

3. Awoodda kulaylka wanaagsan (caabbinta kulaylka hooseeya iyo kuleylka wanaagsan ayaa loo baahan yahay): Sababtoo ah jawiga shaqada ee sanduuqa isku-darka sawir-qaadista badanaa waa mid liita, diode-ka-hortagga wuxuu u baahan yahay inuu yeesho awood wanaagsan oo kulaylka, iyo sida caadiga ah sidoo kale wuxuu u baahan yahay tixgeli xaaladaha cimilada sida Gobi iyo dhulalka.

2. Bypass Diode

Marka ay jiraan qaybo badan oo unug cadceedda ah oo si taxane ah ugu xidhan si ay u sameeyaan unug labajibbaaran ama laan ka mid ah array unug labajibbaaran, hal (ama 2 ~ 3) diodes ayaa loo baahan yahay in lagu xidho si isbarbar-dhig u ah soo saarista togan iyo taban ee batari kasta. guddi.Diodesyada ku xiran isbarbardhigga labada daraf ee qaybta waxaa loo yaqaannaa diodes-ka-dhaafka ah.
Hawsha marin-dhaafka ah waa ka-hortagga qayb gaar ah oo ka mid ah xayndaabka labajibbaaran ama qayb ka mid ah qaybta inay hadh ama cilad yeelato si ay u joojiso korontadda.Eexda hore ayaa laga samayn doonaa labada daraf ee qaybta bypass diode si loo sameeyo habdhaqanka diode.Xadhiga hadda shaqeeyaa waxa uu dhaafaa qaybta khaldan oo waxa uu dhex maraa diode-ka, kaas oo aan saamayn ku yeelanayn korontada qaybaha kale ee caadiga ah.Isla mar ahaantaana, waxay sidoo kale ka ilaalisaa qaybta la dhaafo inay waxyeello u geystaan ​​eexda hore ee sare ama kuleylinta sababtoo ah "saamaynta barta kulul".
Diode-yada la dhaafo ayaa guud ahaan si toos ah loogu rakibay sanduuqa isgoysyada.Marka loo eego awoodda qaybaha iyo tirada xadhkaha unugga baytariga, 1 ilaa 3 diode ayaa lagu rakibay.
Daroosyada la dhaafo looma baahna xaalad kasta.Marka qaybaha keligood loo isticmaalo ama isbarbar socda, uma baahna in lagu xidho diode-ka.Waqtiyada tirada qaybaha taxanaha ahi ay yar yihiin oo jawiga shaqadu wanaagsan yahay, waxa kale oo suurtogal ah in la tixgeliyo in aan la isticmaalin diode-ka dhaafka.

Mabda'a Wareegga Ilaalinta Diode

Shaqada ugu badan ee diode waa in loo ogolaado oo kaliya in uu hadda u gudbo hal jiho (oo loo yaqaan eexda hore) oo uu xannibo jihada rogan (loo yaqaan eexda gadaal).

Marka ay dhaliso eex danab koronto ah oo hor leh, xakameynta wadajirka ah ee garoonka korantada ee dibadda iyo beerta koronto ee iskeed u dhisan ayaa kordhisa qulqulka fidsan ee sidayaasha waxayna sababtaa socodka hore (taas oo ah, sababta korontadu).

Marka eexda danabku soo baxdo, beerta korantada ee dibedda iyo beerta korantada ee iskeed u dhisan ayaa la sii xoojiyaa, samaynta korantada gadaal ee hadda I0 oo aan wax shaqo ah ku lahayn korantada eexda ee qayb ka mid ah korantada gadaasha (tani waa sababta. dhaqan la'aanta).

Marka ay jirto eexda korantada ee bannaanka, beerta korantada ee dibedda iyo beerta korantada ee iskeed u dhisan ayaa la sii xoojiyaa, iyada oo la samaynayo korantada gadaasha ee hadda I0 taas oo ka madax bannaan qiimaha korantada eexda oo ku dhex jirta xadka korantada ee go'an.
