Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, Technology ya olowera yayamba kwambiri. Kafukufuku wovuta wamphamvu wapanganso zina. Pakadali pano, Kuphatikiza pa ogwirizana ndi mphamvu pafupipafupi, Othekera pafupipafupi ayambanso kukhala ndi msika wotukuka wa mphamvu zopitilira muyeso ndipo akuyembekezeka kusintha ma trafwer oyendetsa bwino. Ngakhale olankhula pafupipafupi amakhala ndi zolakwa za olumikizana ndi magetsi amphamvu kwambiri monga kukula kwakukulu, pafupipafupi, ndi luso lotsika, sakanatha kubwezeretsa gawo la ogwiritsira nawo mabwalo amphamvu. Poyerekeza ndi omvera kwambiri, Ophunzira oyendetsa pafupipafupi amakhala ndi maubwino awo apadera. Mphamvu yodziyimira pawokha yopangira chiwembu chokhazikitsidwa ndi makina opanga magetsi amafunsidwa pano.
1. Mphamvu zamphamvu
Maonekedwe 1 ndi chithunzi chojambulidwa cha mphamvu zotchinga kutengera kusinthasintha kwa mawonekedwe (Pwm) zamakompyuta. Chigawo chonse chimasankha zotsika kwambiri za DC ndikuchotsa magetsi a magetsi kudzera mu Bridge. Amasungidwa kwa mtengo womwe wavota ndi magetsi pafupipafupi, kenako mphamvu yamafuta yomwe imakumana ndi zofunikirazo ndikutulutsa gawo. Mwazonse, Zimafunikira kuti zitheke 220V / 50hz Ac.
2. Mphamvu za Mphamvu za Harverter
2.1 Ukadaulo wa PWM
Maziko a ma pwm Controllognology ndi chiwonetserochi. Funde la sine limagwiritsidwa ntchito ngati kusinthasintha kwamphamvu kuti mugwiritse ntchito njira yosinthira yosinthira mawu (Spapt) Ndi chonyamula chomwecho ndikusintha kwamphamvu malinga ndi funde la sine. Siginecha ya Wheel uyu amawonjezeredwa kumbali yotsekemera ya bongo yosinthika yamphamvu imayendetsedwa ndikuzimitsa, ndipo pamapeto pake pali pafupi ndi ma action action action amapezeka. Ukadaulo uwu umapangitsa kuti kuzungulira kwa gawo la Hardware Harth. Maonekedwe 2 ndi chithunzi chojambulira ndi spwm moder pogwiritsa ntchito chipangizo cha U3988 kuti muwongolere mlatho. 0UTA ndi 0uti. Zizindikiro za zigawo za zikhomo ziwirizi nthawi zambiri zimafunikira kudutsa mudera lakufa lolamulira lisanatumizidwe musanatumize. Sinthani mlatho.
2.2 Udindo wa Mphamvu Yopanga Magetsi Mobwereza Bwino
Kulowetsa kwa magetsi oyenda mobwerezabwereza nthawi zambiri kumakhala kotsika kwambiri DC, zomwe zimagwiritsa ntchito mokhazikika. Mtengo wa Peak-Peak-Peak wa UFAAS 220V SIne Thumba la Ac Macy ndi 620V, Pomwe zogulitsa zidakonzanso magetsi a Colleger Power Surget ndi 310V. Pofuna kuti inverter itulutse voliyumu 220V yamagetsi osawonongeka, Magetsi a DC patsogolo pa omwe alowe ayenera 680 ~ 870V. Chifukwa magetsi ophatikizika ndi voliyumu yayikulu kwambiri kuposa mtengo wake, Kutanthauzira kwapakatikati kuyenera kuwonjezeredwa kuti muwonjezere mphamvu yotulutsa yomwe ili pamwamba pamtengo wovota chisanachitike, Monga taonera chithunzi 3.
Dera ili limatengera kapangidwe kake. Kutulutsa kwa chosinthira ichi silaya imodzi yamoyo ndi waya wamba, Koma mawaya awiri amoyo. Komabe, waya wosalowerera nthawi zambiri amafunikira mukalumikizidwa ndi katundu. Ngati palibe wotulutsa mawu otulutsa magetsi ndipo waya wamoyo umalumikizidwa ndi waya wopanda kanthu, Mphamvu yochotsa mphamvu sizigwira ntchito moyenera. Maonekedwe 4 ikuwonetsa njira yomwe ilipo pakatikati pa hafu yamphamvu yopanda tanthauzo.
Itha kuwoneka kuchokera ku chithunzi 4 kuti chifukwa cha mwayi wokhala ndi gawo landale, katundu wamakono sadutsa mu chubu cha rectalifier ndi chubu cholowera mkati mutatha kudutsa katundu, koma amabwerera mwachindunji ku zigawo za Unitral. Pamenepa, Chithunzi chowongolera cha oyang'anira komanso cholowera m'bokosi lazomwe zili pakati pano sizikugwira ntchito. Malinga ndi njira yabwinobwino, Malo omwe alipo adumphira mu chubu cha ockisirier ndi mphamvu ya chubu cholowera m'mabwalo awiri a Bridge. Maonekedwe 5 ikuwonetsa njira yomwe ilipo pakadali pano pali theka lamphamvu. Pomwe kutulutsa mawu kumalumikizidwa ndi wosinthira, yachiwiri (Kutumiza Zinthu Kutha) wa travelfirmary imatha kulumikizidwa ndi mzere wandale, Chifukwa chake kupanga dongosolo lodalirika lamphamvu. Itha kuwoneka kuti chosinthira chotulutsa chija ndi gawo lofunikira pabwalo lolowera, Kupanga Anja Okhazikika ndi khola.
2.3 Chitetezo
U3988 wapanga magetsi opanga magetsi otetezedwa ndi kutetezedwa. Zimangofunika kugawanitsa magetsi kudzera mwankhanza. Mphamvu yamagetsi ikatsika kuposa magetsi, U3988 idzatsekedwa. Kuphatikiza apo, Potengera chitetezo chapano, Kutengera katundu waposachedwa, Pali ntchito zitatu zoteteza: Chitetezo Chachangu, Kuchedwa kwakanthawi komanso kuchedwa.
3. Zolakwika za ovomerezeka
Kusintha kwa chisoto kumalumikizidwa ndi cholinga chosinthira magetsi ndikuyika mzere wandale, ndipo ilibe ntchito yolumikizirana ndi kuwononga masinthidwe. Pali gawo lolowera pakati pa woyamba komanso wachiwiri wa transformer. Amapanga capiko c ndi mphamvu inayake. Kutengeka kwa capictor ndi kofanana ndi pafupipafupi, ndiye:
Mu fomula, XC ndi kuthekera kokwanira kwa gawo lofanana pakati pa Transformer ndi sekondale, mu ω. f ndi pafupipafupi chizindikiro, ku HZ. C ndi gawo lofanana lopangidwa pakati pa pulayimale komanso yachiwiri ya osinthika, mu f.
Itha kuwoneka kuchokera ku equation (1) kuti kuchuluka kwake, Zocheperako, ndiye, kuchuluka kwa chizindikiritso, ndizosavuta kuti ndi njira yothetsera malire. Popeza nthawi zonse zolowerera zigawo zambiri ndizokwera kwambiri, Amatha kuthamangitsidwa mwachindunji kudzera mu transion kuti isokoneze katunduyo. Ngati kusokonekera kochepetsa kumabwera, Zimasintha katundu wosokoneza bongo molingana ndi chiwerengero chosinthira cha transformer. Popeza wosinthirayo alibe ntchito yotsutsa, Zolemba ndi zosefera nthawi zambiri zimawonjezeredwa ndi zowonjezera ndi zomwe zimatulutsa zimatha.
Chifukwa cholumikiza cha kusintha kwa iyo, Zida zotsika kwambiri monga momwe zingakhalire ndi ma capuctors zidzalumikizidwa, zomwe sizingowonjezera kukula kwa madera okha komanso kumawonjezera kugwiritsa ntchito mphamvu yadera ndikuchepetsa mphamvu yotulutsa. Ndi kuchuluka kwa pafupipafupi ndi zida zamtengo wapatali monga ma elekitiki amagetsi, Mtengo wopanga magetsi wogwiritsa ntchito mphamvu zachuluka, Ndipo mtengo wopanga mabatani opangidwa ndi dongosololi achulukanso.
4 Mapeto
Kudzera pakuwunika pamwambapa, kapangidwe kake ndi mawonekedwe a mphamvu yamphamvu yamphamvu yamphamvu yakhazikitsidwa. Chigawo chopangidwa chopangidwa chimaphatikizapo ntchito zapamwamba za zida zamagetsi ndi ntchito yodziwika bwino ya kusintha kwa magetsi kuti akwaniritse cholinga cha kapangidwe kalikonse komanso kodalirika.
