Kusiyana Kwakukulu ndi Magwiritsidwe Ntchito
Ma rectifier ndi zinthu zofunika kwambiri m'mabwalo osiyanasiyana amagetsi ndi machitidwe operekera magetsi. Amasintha alternating current (AC) kukhala direct current (DC), zomwe zimapereka mphamvu yofunikira pazida zambiri ndi mapulogalamu. Pakati pa mitundu yosiyanasiyana ya ma rectifier, ma pulse rectifier ndi ma polarity rectifier obwerera m'mbuyo amadziwika ndi mawonekedwe awo apadera komanso ntchito zawo. Nkhaniyi ikufotokoza kusiyana pakati pa mitundu iwiriyi ya ma rectifier, mfundo zawo zogwirira ntchito, ubwino, kuipa, ndi ntchito.
Zobwezeretsa Mpweya
Ma pulse rectifiers, omwe amadziwikanso kuti pulsed rectifiers kapena controlled rectifiers, ndi zida zomwe zimasintha AC kukhala DC pogwiritsa ntchito zida zolamulidwa za semiconductor monga thyristors kapena silicon-controlled rectifiers (SCRs). Ma rectifiers amenewa amagwiritsidwa ntchito nthawi zambiri pa ntchito zomwe zimafuna kuwongolera bwino mphamvu yamagetsi ndi mphamvu yotuluka.

Kugwira ntchito kwa pulse rectifier kumaphatikizapo kuwongolera ngodya ya gawo la voteji ya AC yolowera. Mwa kusintha ngodya yoyambitsa ya ma SCR, voteji ya DC yotuluka imatha kulamulidwa. SCR ikayambitsidwa, imalola kuti magetsi adutse mpaka AC cycle ifike pa zero, pomwe SCR imazimitsa. Njirayi imabwerezabwereza pa theka lililonse la AC input, ndikupanga pulsating DC output.
Ubwino
Kuwongolera Koyenera: Zowongolera ma pulse zimapereka ulamuliro wabwino kwambiri pa mphamvu yotulutsa ndi mphamvu yamagetsi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zomwe zimafuna mphamvu yosinthika ya DC.
Kuchita Bwino Kwambiri: Zokonzanso izi zimagwira ntchito bwino kwambiri, chifukwa zimachepetsa kutayika kwa mphamvu panthawi yosintha.
Kusinthasintha: Zokonzanso ma pulse zimatha kuthana ndi katundu wosiyanasiyana ndipo ndizoyenera mitundu yosiyanasiyana ya zolowetsa za AC.
Zoyipa
Kuvuta: Kayendedwe ka ma pulse rectifiers ndi kovuta kwambiri kuposa ka ma rectifiers osavuta, omwe amafunikira zinthu zina zowonjezera kuti ayambe kugwira ntchito komanso kuwongolera.
Mtengo: Chifukwa chogwiritsa ntchito zipangizo zowongolera zamagetsi ndi ma circuits owonjezera owongolera, ma pulse rectifier nthawi zambiri amakhala okwera mtengo.
Mapulogalamu
Zokonzanso ma pulse zimagwiritsidwa ntchito kwambiri m'mafakitale, kuphatikizapo:
1.Ma Drive Osinthasintha: Owongolera liwiro la ma mota a AC.
2.Magetsi: Mu magetsi olamulidwa ndi malamulo a zida zamagetsi.
3.Kuwotcherera: Mu zida zowotcherera komwe kuwongolera molondola kwa mphamvu yotulutsa ndikofunikira.
4.Kutumiza kwa HVDC: Mu makina otumizira ma voltage amphamvu (HVDC) kuti agwire bwino ntchito
Zobwezeretsa Zosintha za Polarity
Ma polarity reverse rectifiers, omwe amadziwikanso kuti reverse polarity protection rectifiers kapena reverse voltage protection rectifiers, amapangidwira kuteteza ma circuit ku kuwonongeka komwe kumachitika chifukwa cha kulumikizana kolakwika kwa polarity. Amaonetsetsa kuti circuit ikugwira ntchito bwino ngakhale polarity ya magetsi itasinthidwa.
Mfundo Yogwirira Ntchito
Gawo lalikulu la polarity reverse rectifier ndi diode kapena kuphatikiza kwa ma diode. Akalumikizidwa motsatizana ndi magetsi, diode imalola magetsi kuyenda molunjika. Ngati polarity yasinthidwa, diode imatseka magetsi, zomwe zimaletsa kuwonongeka kwa dera.
Mu mapangidwe apamwamba kwambiri, ma MOSFET (metal-oxide-semiconductor field-effect transistors) amagwiritsidwa ntchito kupereka kutsika kwa voltage yotsika komanso kugwira ntchito bwino kwambiri poyerekeza ndi ma diode. Ma rectifiers opangidwa ndi MOSFET awa amasinthasintha okha ku polarity yoyenera ndikuwonetsetsa kuti dera likugwira ntchito bwino.
Ubwino
Chitetezo cha Dera: Zokonzanso za Polarity reverse zimateteza bwino zida zamagetsi zomwe zili ndi vuto la kuwonongeka chifukwa cha kulumikizana kolakwika kwa polarity.
Kuphweka: Kapangidwe kake ndi kosavuta ndipo kangaphatikizidwe mosavuta m'mabwalo omwe alipo.
Zotsika Mtengo: Zosinthira ma diode-based polarity reverse ndi zotsika mtengo ndipo zimapezeka mosavuta.
Zoyipa
Kutsika kwa Voltage: Zokonzanso zochokera ku diode zimayambitsa kutsika kwa voltage yamtsogolo, zomwe zingachepetse kugwira ntchito bwino kwa dera lonse.
Kuwongolera Kochepa: Zokonzanso izi sizimapereka ulamuliro pa mphamvu yotulutsa mphamvu kapena mphamvu yamagetsi, chifukwa ntchito yawo yayikulu ndi kuteteza.
Mapulogalamu
Ma polarity reverse rectifiers amagwiritsidwa ntchito m'njira zosiyanasiyana pomwe chitetezo ku reverse polarity ndikofunikira, kuphatikizapo:
1.Zipangizo Zamagetsi Zogwiritsidwa Ntchito: Mu zipangizo monga mafoni a m'manja, ma laputopu, ndi zipangizo zina zamagetsi zonyamulika kuti mupewe kuwonongeka chifukwa cha kulumikizana kwa magetsi kolakwika.
2.Magalimoto: Mu zamagetsi zamagalimoto kuti muteteze ma circuit ku ma batire obwerera m'mbuyo.
3.Makina Opangira Mphamvu ya Dzuwa: Kuonetsetsa kuti mapanelo a dzuwa akuyenda bwino komanso kupewa kuwonongeka kwa polarity yobwerera m'mbuyo.
4.Ma Charger a Mabatire: Kuteteza ma circuit ochaja kuti asalumikizidwe ndi batri molakwika.
Kusiyana Kwakukulu

Ngakhale kuti ma pulse rectifiers ndi polarity reverse rectifiers onse amachita ntchito zofunika kwambiri mu machitidwe amagetsi, ntchito zawo ndi momwe amagwiritsidwira ntchito zimasiyana kwambiri.
Ntchito: Ma pulse rectifiers amayang'ana kwambiri pakusintha AC kukhala DC ndikuwongolera bwino zomwe zimatulutsa, pomwe ma polarity reverse rectifiers amapangidwira kuteteza ma circuits ku kuwonongeka chifukwa cha kulumikizana kolakwika kwa polarity.
Zigawo: Zokonzanso ma pulse zimagwiritsa ntchito zipangizo zoyendetsedwa ndi semiconductor monga ma SCR, pomwe zokonzanso ma polarity reverse nthawi zambiri zimagwiritsa ntchito ma diode kapena ma MOSFET.
Zovuta: Zosintha ma pulse ndi zovuta kwambiri ndipo zimafuna ma circuitry owonjezera, pomwe zosintha ma polarity reverse zimakhala ndi kapangidwe kosavuta.
Kugwiritsa Ntchito: Zokonzanso ma pulse zimagwiritsidwa ntchito m'mafakitale ndi m'magetsi amphamvu kwambiri, pomwe zokonzanso ma polarity reverse zimapezeka kwambiri m'magetsi amagetsi, magalimoto, ndi makina amagetsi a dzuwa.
Mapeto
Ma pulse rectifiers ndi polarity reverse rectifiers ndi zinthu zofunika kwambiri m'makina amakono amagetsi, chilichonse chimagwira ntchito yosiyana. Ma pulse rectifiers amapereka kuwongolera kolondola komanso kogwira mtima pakusintha kwa AC kupita ku DC, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'mafakitale. Mosiyana ndi zimenezi, ma polarity reverse rectifiers amapereka chitetezo chofunikira ku maulumikizidwe olakwika a polarity, kuonetsetsa kuti zipangizo zamagetsi ndi machitidwe osiyanasiyana ndi otetezeka. Kumvetsetsa kusiyana pakati pa ma rectifiers awa kumathandiza kusankha gawo loyenera la mapulogalamu enaake, pamapeto pake kumawonjezera magwiridwe antchito ndi moyo wautali wa ma circuits amagetsi.
