Posachedwapa, Navitas adayambitsa CRPS 185 4.5kW AI data center power supply, yomwe imagwiritsa ntchitoYMIN's CW3 1200uF, 450Vcapacitors. Kusankha kwa capacitor uku kumapangitsa kuti magetsi azitha kukwaniritsa mphamvu ya 97% pa theka la katundu. Kupita patsogolo kwaukadaulo kumeneku sikumangowonjezera magwiridwe antchito amagetsi komanso kumathandizira kuti mphamvu zamagetsi ziziyenda bwino, makamaka pochepetsa katundu. Kukula kumeneku ndikofunikira pakuwongolera mphamvu za data center ndikupulumutsa mphamvu, chifukwa kugwira ntchito moyenera sikungochepetsa kugwiritsa ntchito mphamvu komanso kumachepetsa ndalama zogwirira ntchito.
M'machitidwe amakono amagetsi, ma capacitors amagwiritsidwa ntchito osati kokhakusungirako mphamvukomanso kusefa komanso kumagwira ntchito yofunika kwambiri pakuwongolera mphamvu zamagetsi. Mphamvu yamagetsi ndi chizindikiro chofunikira cha magwiridwe antchito amagetsi, ndipo ma capacitor, monga zida zogwirira ntchito zowongolera mphamvu zamagetsi, amakhudza kwambiri kupititsa patsogolo magwiridwe antchito amagetsi. Nkhaniyi iwunika momwe ma capacitors amakhudzira mphamvu yamagetsi ndikukambirana gawo lawo pazogwiritsa ntchito.
1. Mfundo Zoyambira za Capacitors
Capacitor ndi gawo lamagetsi lopangidwa ndi ma conductor awiri (electrodes) ndi insulating material (dielectric). Ntchito yake yayikulu ndikusunga ndi kutulutsa mphamvu zamagetsi mumayendedwe osinthira apano (AC). Pamene magetsi a AC akuyenda kudzera mu capacitor, malo amagetsi amapangidwa mkati mwa capacitor, kusunga mphamvu. Pamene kusintha kwasintha, acapacitorimatulutsa mphamvu zosungidwa izi. Kutha kusunga ndi kumasula mphamvu kumapangitsa kuti ma capacitor azitha kusintha mgwirizano wagawo pakati pa zamakono ndi magetsi, zomwe ndizofunikira kwambiri pogwiritsira ntchito zizindikiro za AC.
Chikhalidwe ichi cha ma capacitors chikuwonekera muzogwiritsira ntchito. Mwachitsanzo, m'mabwalo a fyuluta, ma capacitors amatha kutsekereza Direct current (DC) pomwe amalola kuti ma sign a AC adutse, potero amachepetsa phokoso pazizindikiro. M'makina amagetsi, ma capacitor amatha kusinthasintha kusinthasintha kwamagetsi m'derali, kupititsa patsogolo kukhazikika ndi kudalirika kwamagetsi.
2. Lingaliro la Mphamvu Factor
Mu dera la AC, mphamvu yamagetsi ndi chiŵerengero cha mphamvu yeniyeni (mphamvu yeniyeni) ku mphamvu yowonekera. Mphamvu zenizeni ndi mphamvu zomwe zimasinthidwa kukhala ntchito yothandiza pozungulira, pomwe mphamvu zowoneka ndi mphamvu zonse muderali, kuphatikiza mphamvu zenizeni komanso mphamvu zogwira ntchito. Mphamvu yamagetsi (PF) imaperekedwa ndi:
kumene P ndi mphamvu yeniyeni ndipo S ndi mphamvu yowonekera. Mphamvu yamagetsi imachokera ku 0 mpaka 1, zomwe zimakhala pafupi ndi 1 zomwe zikuwonetsa kugwiritsa ntchito mphamvu kwambiri. Mphamvu yapamwamba imatanthawuza kuti mphamvu zambiri zimasinthidwa bwino kukhala ntchito yothandiza, pamene mphamvu yochepa imasonyeza kuti mphamvu zambiri zimawonongeka ngati mphamvu zowonongeka.
3. Mphamvu Yogwira Ntchito ndi Mphamvu Yamphamvu
M'mabwalo a AC, mphamvu yogwira ntchito imatanthawuza mphamvu yomwe imabwera chifukwa cha kusiyana kwa gawo pakati pa magetsi ndi magetsi. Mphamvu iyi simasintha kukhala ntchito yeniyeni koma imakhalapo chifukwa cha mphamvu zosungira mphamvu za inductors ndi capacitors. Ma inductors nthawi zambiri amabweretsa mphamvu zabwino zogwirira ntchito, pomwe ma capacitor amabweretsa mphamvu zoyipa. Kukhalapo kwa mphamvu yogwira ntchito kumabweretsa kuchepa kwa mphamvu mu dongosolo lamagetsi, chifukwa kumawonjezera katundu wonse popanda kuthandizira ntchito yothandiza.
Kuchepa kwa mphamvu yamagetsi nthawi zambiri kumawonetsa kuchuluka kwa mphamvu zogwira ntchito mozungulira, zomwe zimapangitsa kuchepa kwa mphamvu yonse yamagetsi. Njira imodzi yabwino yochepetsera mphamvu yogwira ntchito ndikuwonjezera ma capacitor, omwe angathandize kukonza mphamvu yamagetsi ndikuwonjezera mphamvu zonse zamagetsi.
4. Zotsatira za Capacitors pa Power Factor
Ma capacitors amatha kusintha mphamvu yamagetsi pochepetsa mphamvu yogwira ntchito. Ma capacitor akagwiritsidwa ntchito pozungulira, amatha kuletsa mphamvu zina zoyambilira zomwe zimayambitsidwa ndi ma inductors, potero amachepetsa mphamvu zonse zogwira ntchito mozungulira. Izi zitha kukulitsa kwambiri mphamvu yamagetsi, ndikuyibweretsa pafupi ndi 1, zomwe zikutanthauza kuti kugwiritsa ntchito mphamvu kwamphamvu kumakhala bwino kwambiri.
Mwachitsanzo, m'makina opangira mphamvu zamafakitale, ma capacitor atha kugwiritsidwa ntchito kubweza mphamvu zomwe zimayambitsidwa ndi zonyamula zonyamula monga ma motors ndi ma transfoma. Powonjezera ma capacitor oyenerera pamakina, mphamvu yamagetsi imatha kuwongolera, kuchepetsa kutayika kwamagetsi ndikuwonjezera mphamvu yogwiritsira ntchito mphamvu.
5. Kusintha kwa Capacitor mu Mapulogalamu Othandiza
Muzochita zothandiza, kasinthidwe ka ma capacitors nthawi zambiri amagwirizana kwambiri ndi chikhalidwe cha katundu. Pazinthu zochititsa chidwi (monga ma motors ndi ma transfoma), ma capacitor angagwiritsidwe ntchito kubweza mphamvu yokhazikika yomwe idayambitsidwa, potero kuwongolera mphamvu yamagetsi. Mwachitsanzo, m'mafakitale opangira mphamvu zamagetsi, kugwiritsa ntchito mabanki a capacitor kumatha kuchepetsa mphamvu yamagetsi pa thiransifoma ndi zingwe, kuwongolera kuyendetsa bwino kwamagetsi ndikuchepetsa kutayika kwamagetsi.
M'malo odzaza kwambiri monga malo opangira ma data, kasinthidwe ka capacitor ndikofunikira kwambiri. Navitas CRPS 185 4.5kW AI data center power supply, mwachitsanzo, imagwiritsa ntchito YMIN'sCW31200uF, 450Vcapacitors kuti akwaniritse mphamvu ya 97% pa theka la katundu. Kukonzekera kumeneku sikungowonjezera mphamvu ya magetsi komanso kumawonjezera mphamvu zonse zoyendetsera deta. Kusintha kwaukadaulo kotereku kumathandizira malo opangira data kuchepetsa kwambiri mtengo wamagetsi ndikuwongolera magwiridwe antchito.
6. Mphamvu ya Half-Load ndi Capacitors
Mphamvu yolemetsa theka imatanthawuza 50% ya mphamvu yovotera. Muzochita zowoneka bwino, kasinthidwe koyenera ka capacitor kumatha kukhathamiritsa mphamvu ya katunduyo, potero kumapangitsa kuti mphamvu yogwiritsira ntchito mphamvu ikhale yokwanira theka la katundu. Mwachitsanzo, injini yokhala ndi mphamvu yovotera ya 1000W, ngati ili ndi ma capacitor oyenerera, imatha kukhala ndi mphamvu yayikulu ngakhale italemera 500W, kuwonetsetsa kugwiritsa ntchito mphamvu moyenera. Izi ndizofunikira makamaka pamapulogalamu omwe ali ndi katundu wosinthasintha, chifukwa amathandizira kukhazikika kwa magwiridwe antchito.
Mapeto
Kugwiritsa ntchito ma capacitor pamakina amagetsi sikungosunga mphamvu ndikusefa komanso kuwongolera mphamvu yamagetsi ndikuwonjezera mphamvu yonse yamagetsi. Mwa kukonza bwino ma capacitor, mphamvu yogwira ntchito imatha kuchepetsedwa kwambiri, mphamvu yamagetsi imatha kukhathamiritsa, ndipo magwiridwe antchito komanso okwera mtengo amagetsi amatha kukulitsidwa. Kumvetsetsa udindo wa ma capacitor ndikuwasintha kutengera momwe zinthu ziliri zomwe zimanyamula ndizofunikira kwambiri pakuwongolera magwiridwe antchito amagetsi. Kupambana kwa Navitas CRPS 185 4.5kW AI data center power supply kukuwonetsa kuthekera kwakukulu ndi ubwino wa luso lamakono la capacitor muzogwiritsira ntchito, kupereka zidziwitso zamtengo wapatali za kukhathamiritsa mphamvu zamagetsi.
