Kusiyanitsa Kwakukulu ndi Ntchito
Ma rectifiers ndi zinthu zofunika kwambiri m'mabwalo osiyanasiyana amagetsi ndi machitidwe opangira magetsi. Amasintha ma alternating current (AC) kuti atsogolere panopa (DC), kupereka mphamvu yofunikira pazida zambiri ndi ntchito. Pakati pa mitundu yosiyanasiyana ya zokonzanso, zosintha ma pulse rectifiers ndi polarity reverse rectifiers ndizodziwika chifukwa cha mawonekedwe awo apadera ndi ntchito. Nkhaniyi ikufotokoza za kusiyana pakati pa mitundu iwiriyi ya okonzanso, mfundo zawo zogwirira ntchito, ubwino, kuipa, ndi ntchito.
Pulse Rectifiers
Ma Pulse rectifiers, omwe amadziwikanso kuti pulsed rectifiers kapena controlled rectifiers, ndi zida zomwe zimasinthira AC kukhala DC pogwiritsa ntchito zida zoyendetsedwa ndi semiconductor monga thyristors kapena silicon-controlled rectifiers (SCRs). Ma rectifiers awa amagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe amafunikira kuwongolera bwino mphamvu yamagetsi komanso yapano.
Mfundo Yogwirira Ntchito
Kagwiritsidwe ntchito ka pulse rectifier kumaphatikizapo kuwongolera mbali ya voteji ya AC. Posintha mawonekedwe oyambira a SCRs, magetsi a DC amatha kuwongolera. SCR ikayambika, imalola kuti masiku ano adutse mpaka kuzungulira kwa AC kukafika zero, pomwe SCR imazimitsa. Izi zimabwerezedwa pa theka lililonse la kulowetsa kwa AC, kutulutsa kutulutsa kwa DC.
Ubwino wake
Kuwongolera Molondola: Zowongolera ma pulse zimapereka mphamvu zowongolera mphamvu zamagetsi zomwe zimatulutsa komanso zapano, zomwe zimawapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira kusintha kwa DC.
Kuchita Bwino Kwambiri: Ma rectifiers awa ndi opambana kwambiri, chifukwa amachepetsa kutayika kwa mphamvu panthawi ya kutembenuka.
Kusinthasintha: Ma pulse rectifiers amatha kunyamula katundu wosiyanasiyana ndipo ndi oyenera mitundu yosiyanasiyana ya zolowetsa za AC.
Zoipa
Kuvuta: Kuzungulira kwa ma pulse rectifiers ndizovuta kwambiri kuposa zowongolera zosavuta, zomwe zimafunikira zida zowonjezera kuti ziyambitse ndikuwongolera.
Mtengo: Chifukwa chogwiritsa ntchito zida zoyendetsedwa ndi semiconductor ndi mabwalo owonjezera owongolera, zowongolera ma pulse nthawi zambiri zimakhala zodula.
Mapulogalamu
Ma Pulse rectifiers amagwiritsidwa ntchito kwambiri pamafakitale, kuphatikiza:
1.Mayendedwe Othamanga Osiyanasiyana: Kuwongolera kuthamanga kwa ma mota a AC.
2.Zida Zamagetsi: Pamagetsi oyendetsedwa ndi zida zamagetsi.
3.Kuwotcherera: Pazida zowotcherera pomwe kuwongolera bwino zomwe zimatuluka ndikofunikira.
4.Kutumiza kwa HVDC: Mu njira zotumizira ma high-voltage direct current (HVDC) kuti zitheke
Polarity Reverse Rectifiers
Polarity reverse rectifiers, omwe amadziwikanso kuti reverse polarity protection rectifiers kapena reverse voltage protection rectifiers, adapangidwa kuti ateteze mabwalo ku kuwonongeka kobwera chifukwa cha kulumikizidwa kolakwika kwa polarity. Amawonetsetsa kuti dera likugwira ntchito moyenera ngakhale polarity yamagetsi ikasinthidwa.
Mfundo Yogwirira Ntchito
Chigawo choyambirira cha polarity reverse rectifier ndi diode kapena kuphatikiza kwa diode. Mukalumikizidwa motsatizana ndi magetsi, diode imalola kuti pakali pano kuyenda munjira yoyenera. Ngati polarity imasinthidwa, diode imatchinga pakalipano, kuteteza kuwonongeka kwa dera.
M'mapangidwe apamwamba kwambiri, ma MOSFET (metal-oxide-semiconductor field-effect transistors) amagwiritsidwa ntchito popereka kutsika kwamagetsi otsika komanso kuchita bwino kwambiri poyerekeza ndi ma diode. Ma rectifiers opangidwa ndi MOSFET awa amasintha okha ku polarity yolondola ndikuwonetsetsa kuti dera likuyenda bwino.
Ubwino wake
Chitetezo Chozungulira: Zosintha za polarity zimateteza bwino zida zamagetsi kuti zisawonongeke chifukwa cha kulumikizana kolakwika kwa polarity.
Kuphweka: Mapangidwe ake ndi osavuta ndipo amatha kuphatikizidwa mosavuta m'mabwalo omwe alipo.
Zotsika mtengo: Zowongolera za Diode-based polarity reverse rectifiers ndi zotsika mtengo ndipo zimapezeka mosavuta.
Zoipa
Kutsika kwa Voltage: Ma diode-based rectifiers amayambitsa kutsika kwamagetsi kutsogolo, komwe kungathe kuchepetsa kuyendetsa bwino kwa dera.
Kuwongolera Kwapang'onopang'ono: Zokonzanso izi sizimapereka mphamvu pamagetsi otulutsa kapena apano, chifukwa ntchito yawo yayikulu ndi chitetezo.
Mapulogalamu
Polarity reverse rectifiers amagwiritsidwa ntchito m'njira zosiyanasiyana pomwe chitetezo ku reverse polarity ndikofunikira, kuphatikiza:
1.Consumer Electronics: Pazida monga mafoni a m'manja, ma laputopu, ndi zida zina zamagetsi kuti mupewe kuwonongeka chifukwa cholumikizidwa ndi magetsi olakwika.
2.Zamagetsi: Mumagetsi amagalimoto kuti muteteze mabwalo kumayendedwe am'mbuyo a batri.
3.Ma Solar Power Systems: Kuwonetsetsa kuti ma solar akugwira ntchito moyenera ndikupewa kuwonongeka kwa reverse polarity.
4.Ma Battery Charger: Kuteteza ma frequency othamangitsa ku mabatire olakwika.
Kusiyana Kwakukulu
Kusiyana Kwakukulu
Ngakhale ma pulse rectifiers ndi polarity reverse rectifiers amagwira ntchito yofunika kwambiri pamakina apakompyuta, ntchito zawo ndi ntchito zimasiyana kwambiri.
Ntchito: Okonzanso ma pulse amayang'ana kwambiri pakusintha AC kukhala DC ndikuwongolera bwino zomwe zimatuluka, pomwe zosinthira polarity zidapangidwa kuti ziteteze mabwalo kuti zisawonongeke chifukwa cha kulumikizana kolakwika kwa polarity.
Zigawo: Zowongolera ma pulse zimagwiritsa ntchito zida zoyendetsedwa ndi semiconductor monga ma SCR, pomwe zosinthira polarity nthawi zambiri zimagwiritsa ntchito ma diode kapena ma MOSFET.
Kuvuta: Zowongolera ma pulse ndizovuta kwambiri ndipo zimafunikira ma controller owonjezera, pomwe zosinthira polarity zili ndi mapangidwe osavuta.
Mapulogalamu: Zowongolera ma pulse zimagwiritsidwa ntchito m'mafakitale ndi magetsi apamwamba, pomwe zowongolera za polarity reverse rectifiers zimapezeka kawirikawiri mumagetsi ogula, magalimoto, ndi ma solar.
Mapeto
Zokonzanso ma pulse ndi polarity reverse rectifiers ndizofunikira kwambiri pamakina amakono amagetsi, chilichonse chimakhala ndi zolinga zake. Ma Pulse rectifiers amapereka chiwongolero cholondola komanso chachangu pakutembenuka kwa AC kupita ku DC, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito ndi mafakitale. Mosiyana ndi izi, ma polarity reverse rectifiers amapereka chitetezo chofunikira ku kulumikizana kolakwika kwa polarity, kuonetsetsa chitetezo ndi kudalirika kwa zida ndi machitidwe osiyanasiyana amagetsi. Kumvetsetsa kusiyana pakati pa okonzansowa kumathandiza posankha chigawo choyenera cha ntchito zinazake, potsirizira pake kumawonjezera ntchito ndi moyo wautali wa mabwalo amagetsi.
