Txheej txheem cej luam ntawm Photovoltaic System
Lub tshuab hluav taws xob photovoltaic hloov lub hnub ci zog rau hauv hluav taws xob los ntawm photovoltaic modules, feem ntau yog tsim los ntawm hnub ci vaj huam sib luag, inverters, controllers, thiab txhawb cov khoom siv hluav taws xob. Hauv cov tshuab photovoltaic, tiam thiab kev xa hluav taws xob hluav taws xob xav tau kev tsim hluav taws xob zoo thiab kev tiv thaiv kev tiv thaiv kom ntseeg tau tias kev ua haujlwm tau zoo thiab kev ruaj ntseg ntev ntawm lub system. Raws li ib feem nrog unidirectional conductivity, diodes ua lub luag haujlwm tseem ceeb hauv kev tswj tam sim no thiab kev tiv thaiv circuits ntawm photovoltaic systems.
Cov kev siv tseem ceeb ntawm diodes hauv photovoltaic systems
Thaiv diode kom tsis txhob rov qab tam sim no
Hauv cov tshuab hluav taws xob photovoltaic, cov tshuaj tiv thaiv rov qab tam sim no yog siv los tiv thaiv tam sim no los ntawm kev ntws rov qab los ntawm lub roj teeb pob mus rau lub hnub ci vaj huam sib luag thaum hmo ntuj lossis hnub huab cua. Hnub ci vaj huam sib luag tsis tuaj yeem tsim hluav taws xob thaum tsis muaj lub teeb. Yog tsis muaj kev tiv thaiv rov qab diodes tam sim no, lub zog hluav taws xob hauv lub roj teeb tuaj yeem ntws rov qab los ntawm lub vaj huam sib luag, ua rau lub zog poob. Qhov tshwm sim no tsis yog tsuas yog nkim lub zog xwb, tab sis kuj yuav ua rau muaj kev puas tsuaj rau lub hnub ci vaj huam sib luag.
Anti rov qab tam sim no diodes feem ntau yog ntsia nruab nrab ntawm lub hnub ci vaj huam sib luag thiab cov roj teeb kom ntseeg tau tias tam sim no tsuas yog ntws los ntawm lub hnub ci vaj huam sib luag mus rau lub roj teeb thiab tsis rov qab. Qhov no yooj yim tab sis tseem ceeb muaj nuj nqi zoo heev txhim khu kev ua tau zoo thiab kev ntseeg siab ntawm photovoltaic systems.
Bypass diode
Bypass diodes feem ntau ntsia nruab nrab ntawm txhua lossis txhua ob peb lub hnub ci vaj huam sib luag hauv photovoltaic modules. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv qhov txo qis hauv cov zis hluav taws xob los ntawm kev cuam tshuam, ua haujlwm tsis zoo, lossis lwm yam laj thawj ntawm qee lub roj teeb vaj huam sib luag. Nyob rau hauv lub photovoltaic system, yog hais tias lub hnub ci vaj huam sib luag muaj ib tug txo nyob rau hauv cov zis voltage vim ntxoov ntxoo, plua plav, los yog kev puas tsuaj, tam sim no ntawm tag nrho cov Circuit Court tej zaum yuav cuam tshuam, yog li txo lub hwj chim tsim efficiency ntawm tag nrho cov photovoltaic system.
Los ntawm kev txhim kho bypass diodes, nws muaj peev xwm hla dhau qhov cuam tshuam ntawm lub rooj tsav xwm roj teeb thaum muaj teeb meem tshwm sim, tso cai rau cov roj teeb uas tseem tshuav ua haujlwm li qub. Qhov no tsis tsuas yog txhim kho qhov kev ua txhaum cai ntawm photovoltaic system, tab sis kuj zam tag nrho lub kaw lus kaw los ntawm kev ua txhaum hauv zos.
Flyback diode
Hauv inverters lossis DC-DC converters ntawm cov tshuab photovoltaic, flyback diodes (tseem hu ua flyback diodes) yog siv los tshem tawm cov thim rov qab electromotive quab yuam tsim los ntawm cov ntsiab lus inductive. Inductive Cheebtsam ua kom muaj qhov hluav taws xob rov qab siab thaum tam sim no dheev disconnects. Yog tias qhov hluav taws xob tsis raug txwv, nws yuav ua rau lwm yam khoom hauv Circuit Court puas.
Rov qab diodes coj thaum rov qab voltage yog tsim nyob rau hauv cov khoom inductive, coj cov tam sim no mus rau txoj kev nyab xeeb thiab tiv thaiv Circuit Court Cheebtsam los ntawm high voltage puas. Daim ntawv thov no tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ruaj ntseg ntawm cov tshuab photovoltaic thiab txuas cov cuab yeej siv lub neej.
Lub luag haujlwm thiab qhov zoo ntawm diodes hauv photovoltaic systems
Txhim kho qhov system efficiency
Los ntawm kev tiv thaiv tam sim no rov qab thiab tiv thaiv lub hnub ci vaj huam sib luag los ntawm cov duab ntxoov ntxoo, diodes ho txhim kho tag nrho cov kev ua tau zoo hauv cov tshuab photovoltaic. Ob qho tib si tiv thaiv rov qab tam sim no diodes thiab bypass diodes tuaj yeem txo lub zog poob thiab ua kom ruaj khov ntawm cov tshuab photovoltaic nyob rau hauv ib puag ncig sib txawv.
Txhim khu kev ntseeg tau
Photovoltaic systems feem ntau yog ntsia sab nraum zoov thiab raug cua thiab hnub ntev, yog li kev ntseeg siab yog qhov tseem ceeb. Daim ntawv thov ntawm diodes zoo txo qhov kev pheej hmoo ntawm kev puas tsuaj los ntawm kev ua txhaum lossis tam sim no surges hauv photovoltaic systems. Los ntawm kev muab kev tiv thaiv tam sim no thiab kev tswj hwm hluav taws xob, diodes kom ruaj khov kev ua haujlwm ntawm lub cev nyob rau hauv ntau yam hnyav.
Txuas lub neej kev pab cuam ntawm cov khoom siv
Cov khoom siv hluav taws xob hauv cov tshuab photovoltaic tuaj yeem cuam tshuam los ntawm ntau yam kev ntxhov siab hluav taws xob thaum lub sijhawm ua haujlwm ntev. Cov nyhuv tiv thaiv ntawm diodes ua rau cov cuab yeej no tiv thaiv los ntawm kev kub ntxhov tam sim no thiab kev puas tsuaj overvoltage, yog li ncua kev pab cuam lub neej ntawm cov cuab yeej, txo cov nqi tu thiab hloov zaus.
Kev txhim kho yav tom ntej ntawm diodes hauv photovoltaic systems
Cov ntaub ntawv zoo dua thiab cov qauv tsim
Nrog rau txoj kev loj hlob ntawm semiconductor technology, cov ntaub ntawv thiab kev tsim ntawm diodes kuj nce mus tas li. Nyob rau hauv lub neej yav tom ntej, npaum thiab tsawg poob Schottky diodes yuav dav siv nyob rau hauv photovoltaic systems. Piv nrog rau cov diodes ib txwm muaj, Schottky diodes muaj qis dua rau pem hauv ntej voltage poob thiab ceev hloov ceev, uas tuaj yeem txo qis zog thiab txhim kho kev ua haujlwm.
Kev txawj ntse thiab kev sib koom ua ke
Nrog rau txoj kev loj hlob ntawm cov ntse photovoltaic systems, cov qauv ntawm integrated diodes yog maj mam tshwm sim. Nyob rau hauv lub neej yav tom ntej, diodes tej zaum yuav muab kev koom ua ke nrog rau lwm yam kev tiv thaiv Cheebtsam, sensors, thiab tswj circuits nyob rau hauv ib tug module los tsim ntse tiv thaiv cov cuab yeej. Cov cuab yeej tiv thaiv ntse no tuaj yeem tsis tsuas yog saib xyuas lub sijhawm ua haujlwm ntawm lub sijhawm tiag tiag ntawm lub cev, tab sis kuj tseem hloov kho qhov ntsuas hluav taws xob raws li qhov xwm txheej tiag tiag, ntxiv dag zog rau kev ruaj ntseg thiab kev ua haujlwm ntawm lub system.
Daim ntawv thov hauv New Photovoltaic Systems
Nrog rau kev nce qib ntawm cov thev naus laus zis thev naus laus zis thev naus laus zis, cov thev naus laus zis tshiab photovoltaic xws li nyias-zaj duab xis hnub ci hlwb thiab cov khoom siv hluav taws xob photovoltaic (CPV) maj mam nkag mus rau hauv kev ua lag luam. Cov tshuab photovoltaic tshiab no muaj cov kev xav tau siab dua rau kev tiv thaiv hluav taws xob thiab muab sijhawm tshiab rau kev siv diodes. Nyob rau hauv lub neej yav tom ntej, kev tsim thiab kev siv cov diodes tshwj xeeb rau ntau hom photovoltaic systems yuav dhau los ua kev tshawb fawb hotspot, txhawb kev txhim kho ntxiv ntawm kev lag luam photovoltaic.
