Kukosha kwe photovoltaic diodes mukugadzira simba rezuva

Muchikamu cheskweya chesolar cell, diode chishandiso chakajairika, diode inowanzo shandiswa ndeye silicon rectifier diode, mukusarudzwa kwezvakatemwa kuchengetedza paramita, kudzivirira kuparara kwekukuvara.Kazhinji, iyo reverse peak breakdown voltage uye iyo yakanyanya kushanda ikozvino inofanira kunge inopfuura 2 nguva dzeyakanyanya kushanda voltage uye inoshanda ikozvino.Kune marudzi maviri makuru e diode mu photovoltaics systems.

Diode yekudzivirira reverse kuchaja (kudzivirira reverse ikozvino)

Rimwe remabasa eDiode ekudzivirira kudzivirira reverse kuchaja (kudzivirira kuchaja reverse) kudzivirira ikozvino kwesero rezuva kuti isadzoserwe kune solar cell kana square array kana solar cell kana square array isiri kugadzira magetsi. basa riri mubhatiri array, kudzivirira ikozvino pakati pematavi eiyo array yakadzoserwa.Izvi zvinodaro nekuti magetsi ekubuda kwebazi rega rega munhevedzano haagone kuenzana zvachose, panogara paine musiyano pakati peiyo yakakwira uye yakaderera voltage yebazi rega rega, kana iyo inobuda voltage yebazi inodzikiswa nekuda kwekukanganisa kwebazi rimwe, shading. , zvichingodaro, ikozvino yebazi repamusoro-voltage inoyerera ichienda kune yakaderera voltage bazi uye kunyange kuderedza iyo yakazara inobuda voltage yesquare array.Ichi chiitiko chinogona kudzivirirwa nekubatanidza anti-back-filling diode munhevedzano mubazi rega rega.

Slocable'sAnti-Reverse Diodeine yakatemerwa voltage ye1600V, magetsi ega ega anosvika 3100V pakati pechip neiyo substrate, girazi rakapfuura chip kutengeswa, yakanakisa tembiricha hunhu uye simba rekumhanyisa bhasikoro, uye silicon carbide diode, kupfuura yakajairika diode mashandisiro emagetsi anopfuura gumi nemashanu. %.Yakarongwa ikozvino kusvika ku55 A. Kana hurongwa hwako huine chiyero chezvino chepamusoro pe12A, iyi diode inokurudzirwa kuchengetedza zvikamu zvako.

Bypass diode

Kana mamwe solar cell modules akabatanidzwa munhevedzano kuti aite bazi resero array kana sero array, imwe (kana maviri kana matatu) diode inoda kubatanidzwa mune reverse parallel pane yakanaka uye isina kunaka inobuda materminal ega rega rega, diode iyi. , iyo yakabatanidzwa mukuwirirana kumativi ose eGungano, inonzi bypass diode.

Basa rebypass diode ndere kudzivirira chikamu kana chikamu chechikamu muskweya array kuti chisave nemumvuri kana kumiswa kubva mukugadzirwa kwemagetsi kana kutadza, nhevedzano yezvino yezvikamu inodarika izvo zvinokanganisa uye inoyerera nemu diode pasina. inokanganisa kugadzirwa kwemagetsi ezvimwe zvinhu zvakajairika, ukuwo ichidzivirira zvikamu zvakapfuura kubva kumusoro kumberi kana kukuvara nekuda kwe“Hot spot effect”kudziyisa.

Bypass diodes inowanzoiswa yakananga mubhokisi rejunction, zvichienderana nehukuru hwechikamu chesimba uye huwandu hwemabhatiri, kuiswa kwe1 ~ 3 diode.

Iyo by-pass diode haidiwi mune chero mamiriro ezvinhu, kana zvikamu zvinoshandiswa chete kana zvakafanana, hazvidiwi kubatanidza diode.Nokuda kwezvikamu zvishoma mumutsara uye nzvimbo yakanaka yekushanda, unogonawo kufunga nezvekushandiswa kwebypass diodes.
