Popeza kukula kwake kukuchepa ndi 30% ndikuwonjezera nthawi yogwira ntchito kangapo, makampani opanga magetsi akusinthasintha pang'onopang'ono.
Mukalowa m'sitolo yogulitsa zinthu zapakhomo, kodi mwaona kuti magetsi aposachedwa a LED akuchepa kwambiri komanso akukonzedwa bwino? Madalaivala asintha kuchoka pa "mabokosi akuda" akuluakulu kukhala ma module opepuka. Kumbuyo kwa kusinthaku kuli kupita patsogolo kwa ukadaulo wa gallium nitride (GaN) ndi ma capacitor ang'onoang'ono, zomwe zikuyendetsa makampani opanga magetsi kuti azigwira ntchito pang'onopang'ono komanso kuti azigwira ntchito bwino kwambiri.
Monga maziko a kuwala, chowongolera cha LED chimatsimikizira mwachindunji kuwala, nthawi yogwira ntchito, ndi kukhazikika kwa nyali. Ma capacitor, monga gawo lofunikira la chowongolera, akuwona kupita patsogolo kwaukadaulo kusintha mawonekedwe ndi magwiridwe antchito a zinthu zowunikira.
01 Kusintha kwa Capacitor Pansi pa Kachitidwe ka Miniaturization
Makampani opanga magetsi akusintha kuchoka pa nyali zachikhalidwe za fluorescent ndi halogen kupita ku nyali za LED. Kuunikira kwa LED kwakhala kofala kwambiri, komwe kumagwiritsidwa ntchito kwambiri m'nyumba, m'mabizinesi, pazadzidzidzi, komanso m'misewu.
Ndi kupita patsogolo kwa ukadaulo wa gallium nitride (GaN) wopangidwa ndi ma frequency apamwamba komanso ogwira ntchito kwambiri, zinthu zowunikira za LED zalowa mu nthawi yatsopano ya miniaturization ndi micro-miniaturization. Kubwerezabwereza kwa ukadaulo kumeneku kumapangitsa kuti pakhale kufunikira kwakukulu kwa zida zamagetsi zothandizira, makamaka ma capacitor a aluminium electrolytic.
Mphamvu zamagetsi za LED zoyendetsedwa ndi miniaturized zimafuna zida zamagetsi zoyendetsedwa ndi miniaturized. Ma capacitor a aluminiyamu electrolytic, monga gawo lofunikira, amafunika kukhala ndi magwiridwe antchito abwino kwambiri amagetsi, mawonekedwe a kutentha, komanso kukana kupitirira muyeso pamene akuchepetsa kukula.
Kuunikira kwamkati, monga nyali za babu, kumafuna kuunikira kwa 270° kapena 360°, komwe kumafuna kuunikira kofanana ndi nyali za incandescent. Izi zimapangitsa kuti magetsi oyendetsa azigwiritsidwa ntchito pang'ono.
02 Ubwino wa Ukadaulo wa YMIN Capacitors
Monga mtsogoleri pa ntchito ya ma capacitor ang'onoang'ono, YMIN Electronics yakhala ikukula msika wa magetsi kwa zaka zoposa makumi awiri. Zogulitsa zake zimakwaniritsa zofunikira kwambiri za gallium nitride (GaN) LED zamagetsi a ma capacitor.
Zogulitsa za YMIN za LKM zosungunuka pang'ono zili ndi ubwino monga kukula kochepa kwambiri, kuchuluka kwa mphamvu, chitetezo cha mphezi, kukana kwamkati kochepa, komanso kukana kwa ripple kwambiri, zomwe zimagwirizana bwino ndi mawonekedwe apamwamba komanso ogwira ntchito bwino a GaN.
Kukula kochepa komanso mphamvu zambiri zimathandiza kupanga njira zatsopano za GaN kukhala zazing'ono, pomwe kukana kwamkati kotsika kwambiri kumathandizira kuti capacitor ikhale yolimba kwambiri ikalowa, kumachepetsa kutentha kwa thupi la capacitor, motero kumathandizira kwambiri magwiridwe antchito a magetsi a LED.
Poyerekeza ndi zinthu zachikhalidwe, ma capacitor ang'onoang'ono a YMIN achepetsa kukula ndi 15%-30%, pomwe akusunga mphamvu zamagetsi zambiri, kukwera kwa kutentha, ESR, ndi mphamvu yolimbana ndi ma ripple current. Kutalika kwa nthawi ya chinthu ndi kukana kupitirira muyeso ndizofanana ndi zitsanzo zisanayambe kuchepetsedwa.
03 Kuthetsa Mavuto Okhudza Kuunikira
Ma capacitor a YMIN amasonyeza kufunika kwapadera pa ntchito yowunikira mwanzeru. Ma capacitor awo a VKM series a aluminiyamu electrolytic capacitors amapangidwira makamaka malo otentha kwambiri a magetsi anzeru, kusunga mphamvu yosungira mphamvu yoposa 80% pa -40°C, kuthetsa mavuto ovuta kuyambitsa kutentha kochepa komanso nthawi yochepa ya nyali za LED.
Pa kutentha kwa 105°C, ma capacitor a YMIN amakhala ndi moyo wa maola 10,000, ndipo mphamvu yotuluka yachepa kwambiri, zomwe zimathandiza kwambiri kuti ntchito zowunikira mwanzeru zikhale zodalirika.
Poyang'anizana ndi chizolowezi cha magetsi anzeru a magalimoto, ma capacitor a YMIN amagwiranso ntchito bwino kwambiri. Ma capacitor awo amadzimadzi okhala pamwamba pamadzi ndi ma electrolytic capacitor a aluminiyamu okhala ndi madzi olimba ali ndi mawonekedwe otsika a ESR, kusefa phokoso losochera ndi kusokoneza mu dera ndikuwonetsetsa kuti kuwala kwa magetsi kumakhala kokhazikika.
ESR yotsika imatsimikizira kuti capacitor imasunga kutentha kochepa kwa ripple pamene mafunde akuluakulu a ripple akudutsa, zomwe zimakwaniritsa zofunikira pakutaya kutentha kwa magetsi a magalimoto ndikuwonjezera nthawi yawo ya moyo.
04 Mapempho Ogwiritsira Ntchito ndi Zotsatira za Makampani
Pakadali pano, ma capacitor ang'onoang'ono a YMIN adziwika bwino komanso kukondedwa ndi makampani otsogola owunikira m'dziko muno komanso padziko lonse lapansi monga Philips ndi Opple, omwe akuchita gawo lofunika kwambiri pamsika wamagetsi apamwamba.
YMIN yakhazikitsa mizere isanu ndi iwiri yayikulu ya zinthu zopangira ma capacitor, kuphatikiza ma capacitor a electrolytic amadzimadzi a aluminiyamu, ma capacitor a polymer solid-state, ndi ma capacitor a electrolytic a solid-liquid hybrid aluminum. Mndandanda wazinthu zolemerazi umakwaniritsa zofunikira zapamwamba pazochitika zosiyanasiyana.
Ndi kukweza ntchito zowunikira zamagalimoto anzeru, chiwerengero cha ma LED omwe amagwiritsidwa ntchito mkati chimawonjezeka, ndipo mphamvu yogwirira ntchito ndi yayikulu, zomwe zimafuna ma capacitor ogwira ntchito kwambiri kuti apereke ntchito zosungira mphamvu zokhazikika komanso zosefera. Ma capacitor a YMIN amakwaniritsa bwino kufunikira kwa msika kumeneku.
Potsatira mfundo yakuti “Pa ntchito za capacitor, ngati muli ndi mavuto, pezani YMIN,” YMIN imapereka chithandizo champhamvu pa mapangidwe atsopano a makasitomala ndi zinthu zatsopano komanso zopikisana, zomwe zikuyendetsa chitukuko cha makampani onse owunikira.
Ma capacitor a electrolytic a aluminiyamu osakanikirana ndi madzi a YMIN ndi ma capacitor a electrolytic a aluminiyamu okhala pamwamba pa madzi agwiritsidwa ntchito bwino pakuwunika kwanzeru kwa magalimoto. Ma ESR awo otsika, kulekerera kwamphamvu kwa ripple current, komanso nthawi yayitali yogwira ntchito zimathandiza kuthetsa ululu wa ntchito yosakhazikika komanso nthawi yochepa yogwira ntchito m'magetsi a magalimoto.
Kuyambira panyumba mpaka pamagalimoto, kuyambira pa kuunikira wamba mpaka pa kulamulira mwanzeru, kuchepetsedwa kwa ma capacitor kukusintha pang'onopang'ono momwe timagwirira ntchito ndi kuwala.
