Lub hnub ci hluav taws xob tsim hluav taws xob yog tsim los ntawm kev siv lub hauv paus ntsiab lus ntawm cov nyhuv photovoltaic. Nws yog lub zog tsim hluav taws xob uas ncaj qha hloov lub hnub ci hluav taws xob rau hauv hluav taws xob hluav taws xob. Nws tsuas yog muaj ob ntu: hnub ci cell array thiab inverter. Raws li pom nyob rau hauv daim duab hauv qab no: Thaum muaj hnub ci thaum nruab hnub, hluav taws xob tsim los ntawm lub hnub ci cell array ncaj qha xa mus rau AC lub zog hluav taws xob los ntawm daim phiaj-txuas inverter, lossis cov hluav taws xob tsim los ntawm lub hnub ci hluav taws xob ncaj qha mus rau lub zog hluav taws xob. AC load los ntawm daim phiaj-txuas inverter.
Hnub ci photovoltaic lub zog tsim hluav taws xob tso siab rau lub hnub ci cell modules thiab cov khoom hluav taws xob ntawm cov khoom siv semiconductor. Thaum tshav ntuj ci rau ntawm qhov sib txuas ntawm semiconductor PN, PN junction barrier cheeb tsam tsim ib qho chaw muaj zog hauv electrostatic teb, yog li cov hluav taws xob tsis sib haum thiab qhov tshwm sim hauv cheeb tsam teeb meem lossis cov hluav taws xob tsis sib haum thiab qhov tshwm sim sab nraum thaj tsam barrier tab sis diffused mus rau hauv qhov thaiv. cheeb tsam, nyob rau hauv qhov kev txiav txim ntawm lub built-in electrostatic teb, txav nyob rau hauv opposite lus qhia thiab tawm hauv lub barrier cheeb tsam, uas ua rau ib tug nce nyob rau hauv lub peev xwm ntawm lub P cheeb tsam thiab ib tug txo nyob rau hauv lub peev xwm ntawm lub N cheeb tsam, yog li tsim voltage thiab tam sim no. nyob rau hauv sab nraud Circuit Court, hloov lub teeb lub zog mus rau hauv hluav taws xob lub zog.
Hnub ci photovoltaic zog tsim tshuab tuaj yeem faib ua ob pawg. Ib qho yog cov kab hluav taws xob txuas hluav taws xob tsim hluav taws xob, uas txuas nrog rau pej xeem cov hluav taws xob hluav taws xob los ntawm cov qauv sib txuas, zoo li lub tshuab hluav taws xob me me; Lwm qhov yog lub zog tsim hluav taws xob ywj pheej, uas tsim ib lub voj voog hauv nws tus kheej kaw-circuit system. Cov kab hluav taws xob txuas txuas hluav taws xob hloov hluav taws xob tau txais lub hnub ci hluav taws xob rau hauv high-voltage direct tam sim no los ntawm photovoltaic array los ntawm high-frequency ncaj tam sim no hloov dua siab tshiab, thiab ces outputs ib tug sinusoidal alternating tam sim no nrog tib zaus thiab theem raws li daim phiaj voltage rau lub kab sib chaws tom qab tau inverted los ntawm lub inverter. Lub photovoltaic array ntawm lub zog tsim hluav taws xob ywj pheej yuav ua ntej hloov lub hnub ci hluav taws xob uas tau txais ncaj qha mus rau hauv hluav taws xob lub zog los muab cov khoom thauj, thiab khaws cia cov hluav taws xob ntau dhau hauv lub roj teeb hauv daim ntawv ntawm cov khoom siv hluav taws xob tom qab dhau los ntawm kev them nyiaj.
