Pakadali pano, kutsata kwa New Photovoltaltaic kumachitika makamaka dongosolo la DC, lomwe ndikulipiritsa mphamvu yamagetsi yopangidwa ndi bala la dzuwa, ndipo batire limapereka mphamvu kwa katundu. Mwachitsanzo, kuwunika kwa dzuwa kumpoto chakumadzulo kwa China ndi microwave station mphamvu yoyendetsa ndege kutali kwambiri ndi GRID System yonse. Mtundu wamtunduwu uli ndi kapangidwe kake komanso mtengo wotsika. Komabe, chifukwa cha magetsi osiyanasiyana a DC (monga 12v, 24V, 48V, ndi zina zambiri), makamaka kwa mphamvu zaboma, monga momwe ambiri amagwiritsidwira ntchito ndi DC. Ndikosavuta kuti pakhale mphamvu ya Photovoltaltaction kuti ipereke magetsi kuti mulowe pamsika ngati katundu. Kuphatikiza apo, Photophvultal Maulamuliro akwaniritsa ntchito yolumikizidwa, yomwe iyenera kutengera mtundu wa msika wokhwima. M'tsogolo, magetsi a ac Corger Stud Systems udzakhala chikuluzikulu cha m'badwo wa Photovoltal.
Zofunikira za Photovovoltaic Groust dongosolo la oyendetsa mphamvu
Magetsi oyendetsa a Photovoltaic Exf Revices amagwiritsa ntchito masheya anayi: Chithunzithunzi Chomangira, batire ndi infler (gulu lolumikizidwa ndi gawo lalikulu. Photovovoltaic ili ndi zofunikira kwambiri kwa othandiza:
1. Kuchita bwino kwambiri kumafunikira. Chifukwa cha mtengo wokwera wa maselo a dzuwa pakalipano, kuti athe kukulitsa kugwiritsa ntchito maselo a dzuwa ndikusintha mphamvu, ndikofunikira kuyesa kukonza njira yomwe mungakwaniritsire bwino.
2. Kudalirika kwakukulu ndikofunikira. Pakadali pano, punvoltaic mphamvu zokhala m'badwo zimagwiritsidwa ntchito makamaka kumadera akutali, ndipo malo ambiri olamulira samasamalidwa ndikusungidwa. Izi zimafuna kuti inverter ikhale ndi gawo loyenerera, kusankhana kosakhazikika, ndipo amafuna kuti wovota azikhala ndi chitetezo chokwanira cha DC, kutengera kutetezedwa kwa DC
3. Popeza magetsi osinthika a batri ndi katundu ndi kukula kwa dzuwa, ngakhale kuti batiri limakhala ndi gawo lofunikira pa balulu la batri, magetsi amasinthasintha batire ndi kukana kwamkati. Makamaka pamene betri ikukalamba, mphamvu yake yamagetsi imasiyanasiyana. Mwachitsanzo, magetsi okhazikika a batri 12 v mpaka 16 V. Izi zimafuna kuti wolowetsa azigwira ntchito yowonjezera ndi kukhazikika kwa magetsi akulu ndikuwonetsetsa kuti magetsi azitulutsa.
4. Mwa ma purvoluc ndi akulu-okwera pa 7 Izi zili choncho chifukwa mwa njira zapakatikati komanso zazikulu, ngati mphamvu ya Swene Sweden zimagwiritsidwa ntchito, zomwe zidanenedwa zimakhala ndi zigawo zambiri, ndipo magwiridwe apamwamba amatulutsa zotayika. Ambiri a Photovoltaic Oneltals amadzaza ndi kulumikizana kapena zida zamagetsi. Zipangizozi zili ndi zofunika kwambiri pamtengo wamagetsi. Pamene sing'anga yolimba ndi yayikulu kwambiri yolumikizidwa m'badwo wolumikizidwa ndi gululi, kuti mupewe kuipitsidwa kwamphamvu ndi gululi, yemweyo amafunikiranso kuti atulutse azungu.
Olowetsa asing'anga amatembenuza mwachindunji pakadali pano. Ngati voliyumu yovomerezeka ili yotsika, imasungidwa ndi njira yomwe ingasinthidwe kuti ipeze muyeso wa voliyumu komanso pafupipafupi. Kwa ogwirizana ndi mabizinesi akuluakulu, chifukwa cha ma burter apamwamba a DC, zotulukapo zomwe sizimafunikira kusinthasintha kuti zikulitse voliyumuyo mpaka 220V. Mu ogwirizana ndi ogwirizana ndi DC Othandizana ndi ocheperako nthawi zambiri amaphatikizira mabwalo osinthika, otsetsereka a Bridy and infler ndi pafupipafupi-pafupipafupi amalimbikitsa madera osokoneza bongo. Mabwalo akukankhira kuti alumikizane ndi kusintha kwamphamvu kwa magetsi, ndipo machubu awiri amatulutsa, chifukwa omasulira amalumikizidwa ndi nthawi yayitali, motero amawongolera kudalirika kwa dera. Zovuta ndikuti kusinthika kwa kusinthika ndizotsika komanso kuthekera koyendetsa katundu wopanda pake ndi wosauka.
Chigawo cha BRID-Bridy cholowera chimathera zolakwa za madera okankha. Mphamvu ya mphamvu imasintha mawonekedwe otulutsa, ndipo phindu lothandiza limasinthana chifukwa chake. Chifukwa chakuti madera ali ndi chiuno chomasuka, ngakhale kwa katundu wosangalatsa, mphamvu yamagetsi yotulutsa sizingapotozedwe. Choyipa cha derali ndichakuti mphamvu ya mikono yam'mwambamwamba ndi yotsikira sizigawana nthaka, kotero madera odzipereka kapena oyendetsa magetsi akutali ayenera kugwiritsidwa ntchito. Kuphatikiza apo, pofuna kupewa kuphatikizika kofala kwa mikono yapamwamba komanso yotsika ya mladi.
Kutulutsa kwa Push-Kor-Kor-Brid-Bridge Ayenera kuwonjezera njira yosinthira. Chifukwa choti wosinthira mbali ndi wamkulu kukula, otsika kwambiri, komanso okwera mtengo, okhala ndi ukadaulo wamagetsi, ma technology osinthika amagwiritsidwa ntchito kuti akwaniritse zosintha kwambiri. Kutsogolo kwa gawo lakutsogolo kwa dera la osinthika kumeneku kumatengera kapangidwe ka kukoka, koma pafupipafupi ntchito kuli pamwamba 20kHz. Kutumiza kwamphamvu kumatengera maginito apamwamba kwambiri, chifukwa chake ndi ochepa kukula ndi kuwala kolemera. Pambuyo pa kusinthika kwapafupi kwambiri, kumasinthidwa kukhala pafupipafupi kusinthana komwe kudzera munjira yosinthira pafupipafupi, kenako pamwamba pa 400V
Ndi kapangidwe kake kameneka, mphamvu ya wolowezi imayenda bwino kwambiri, kuwonongeka kwa mmodziyo kuchepetsedwa, ndipo kuchita bwino kwake. Choyipa cha madera ndichakuti derali ndilovuta komanso kudalirika ndikotsika kuposa mabwalo awiri pamwambapa.
Kuwongolera madera a mdera
Madera akuluakulu a m'magulu omwe atchulidwa pamwambapa onse amafunika kukwaniritsidwa ndi dera lolamulira. Nthawi zambiri, pali njira ziwiri zoyendetsera: Mkulu wa funde ndi mafunde ofowoka. Mphamvu yolowera mozungulira ndi yotulutsa ndi yosavuta, yotsika mtengo, koma yotsika kwambiri komanso yayikulu mumitundu inayake. . Kutulutsa kwa sine ndikupanga ma trend olumikizana. Ndi chitukuko cha ukadaulo wa microectronics, microcessions omwe ali ndi ntchito za pwm atulukanso. Chifukwa chake, umphumi wa mtima wa a Sine Wavey kutulutsa udakhwima.
1. Osintha ndi mawu owuma pakadali pano amagwiritsa ntchito makina opindika posinthira mawu, monga SG 3 524 ndi zina 494 ndi zina. Kuchita kwatsimikizira kuti kugwiritsa ntchito madera a SG3525 ndikugwiritsa ntchito mapangidwe a mphamvu monga kusintha magawo kungakwaniritse ntchito zapamwamba komanso zopindika. Chifukwa SG3525 imatha kuyendetsa mwachindunji mphamvu yamphamvu ndipo ili ndi gwero lamkati komanso othandizira ogwirira ntchito komanso oteteza chitetezo, motero dera lake la zopepuka ndilosavuta.
2. Kuwongolera komwe kumaphatikizidwa ndi sinetsani Fund, malo owongolera omwe ali ndi microprocer, monga 80 c 196 MC Corporation, ndikupangidwa ndi kampani ya Motorola. Mp 16 ndi pi 12 c 73 yopangidwa ndi mil chip kampani, etc. M'nthawi yakufa, gwiritsani ntchito Intel Kampani ya anthu 80 c 196 mc kuti azindikire kuti mibadwo ya Aminive Sungani Zizindikiro, ndipo onani magetsi a a AC kuti mukwaniritse voliyutirization.
Kusankhidwa kwa zida zamagetsi mdera lalikulu
Kusankha kwa zigawo zazikulu zavitandizofunikira kwambiri. Pakadali pano, zida zamagetsi zogwiritsidwa ntchito kwambiri ndizophatikiza mphamvu za Darlington (BJT), mphamvu ya Power Axprors (Mos-F et), adapereka chipata chosanja (iGB). T) ndi kutembenuza alristor (GTO), ndi zida zogwiritsidwa ntchito kwambiri mu magetsi ocheperako, chifukwa fetle ya Mosper ili ndi mphamvu yosinthira ya magetsi kwambiri ndi magetsi ambiri. Izi ndichifukwa choti kukana kwa Mos Fat Fat kumawonjezeka ndi kuchuluka kwa magetsi, ndipo ig bt ali mu njira zapakatikati zimakhala ndi mphamvu yayikulu kwambiri, pomwepo ponseponse), ma gtos nthawi zambiri amagwiritsidwa ntchito ngati zigawo zamphamvu.
