IC tchipisi tating'onoting'ono timene timayang'anira kutembenuka kwamagetsi, kugawa, kuzindikira ndi kasamalidwe kena kamagetsi mumagetsi amagetsi.Semiconductor yoyang'anira mphamvu kuchokera ku zida zomwe zili, kutsindika momveka bwino kasamalidwe kamagetsi kaphatikizidwe kagawo (mphamvu kasamalidwe ka IC, yotchedwa power management chip) udindo ndi udindo.Power management semiconductor imaphatikizapo magawo awiri, omwe ndi kasamalidwe ka mphamvu kaphatikizidwe kagawo ndi kasamalidwe kamagetsi kachipangizo ka semiconductor.
Pali mitundu yambiri yamagawo ophatikizika a kasamalidwe ka mphamvu, omwe amatha kugawidwa m'magawo owongolera ma voltage ndi mawonekedwe.Voltage modulator imaphatikizapo chowongolera chotsitsa chamagetsi otsika (ie LOD), mayendedwe abwino ndi oyipa, kuphatikiza, palibe pulse wide modulation (PWM) mtundu wosinthira, ndi zina zambiri.
Chifukwa cha kupita patsogolo kwaukadaulo, kukula kwapang'onopang'ono kwa digito mu chipangizo chophatikizika chophatikizika kukucheperachepera, kotero mphamvu yogwira ntchito ikupita kumagetsi otsika, ndipo zowongolera zatsopano zingapo zimatuluka panthawi yoyenera.Mawonekedwe amagetsi oyendetsera magetsi makamaka amaphatikiza dalaivala wa mawonekedwe, oyendetsa galimoto, oyendetsa MOSFET ndi oyendetsa ma voltage apamwamba / apamwamba kwambiri, ndi zina zambiri.
Mitundu isanu ndi itatu yodziwika bwino ya kasamalidwe ka mphamvu ya IC chip classification
Zida zogwiritsira ntchito mphamvu zopangira semiconductor zimaphatikizapo zida zina zachikhalidwe za semiconductor, zomwe zingathe kugawidwa m'magulu awiri, limodzi limaphatikizapo rectifier ndi thyristor;Wina ndi mtundu wa triode, kuphatikiza mphamvu ya bipolar transistor, yokhala ndi MOS structure power field effect transistor (MOSFET) ndi insulated gate bipolar transistor (IGBT).
Mwa zina chifukwa cha kuchuluka kwa ma ics oyang'anira mphamvu, ma semiconductors amagetsi adasinthidwa kukhala ma semiconductors owongolera mphamvu.Ndi chifukwa chakuti mabwalo ambiri ophatikizika (IC) m'malo operekera magetsi, anthu amangoyang'ana kasamalidwe kamagetsi kuti atchule gawo lamakono laukadaulo wamagetsi.
Power management semiconductor mu gawo lotsogola la IC kasamalidwe ka mphamvu, ikhoza kufotokozedwa mwachidule monga 8 zotsatirazi.
1. AC/DC kusinthasintha kwa IC.Lili ndi otsika ma voltage control circuit ndi high voltage switching transistor.
2. DC/DC kusintha kwa IC.Mulinso zowongolera zolimbikitsa / zotsika pansi, ndi mapampu opangira.
3. mphamvu factor control PFC pretuned IC.Perekani gawo lolowera mphamvu ndi ntchito yowongolera mphamvu.
4. pulse modulation kapena pulse amplitude modulation PWM/PFM control IC.Makina osinthira ma pulse frequency modulation ndi/kapena pulse wide modulation controller poyendetsa ma switch akunja.
5. linear modulation IC (monga liniya low voltage regulator LDO, etc.).Mulinso owongolera amtsogolo ndi oyipa, ndi machubu osinthira ma voltage otsika a LDO.
6. Kuthamanga kwa batri ndi kasamalidwe ka IC.Izi zikuphatikiza kuyitanitsa kwa batri, chitetezo ndi ma ics owonetsera mphamvu, komanso ma "smart" ma ics a batri a kulumikizana kwa data ya batri.
7. Hot swap board control IC (yopanda kukhudzidwa ndi kuyika kapena kuchotsa mawonekedwe ena panjira yogwirira ntchito).
8. MOSFET kapena IGBT kusintha ntchito IC.
Pakati pa maics oyang'anira mphamvu awa, ma voltage regulation ICS ndi omwe akukula mwachangu komanso opindulitsa kwambiri.Ma ics osiyanasiyana oyang'anira mphamvu nthawi zambiri amalumikizidwa ndi mapulogalamu angapo okhudzana, kotero mitundu yambiri ya zida zitha kulembedwa pamapulogalamu osiyanasiyana.
Mchitidwe waukadaulo wowongolera mphamvu ndikuchita bwino kwambiri, kugwiritsa ntchito mphamvu zochepa komanso luntha.Kupititsa patsogolo mphamvu kumaphatikizapo mbali ziwiri zosiyana: kumbali imodzi, kusinthika kwa mphamvu zonse kumasungidwa pamene kuchepetsa kukula kwa zipangizo;Kumbali inayi, kukula kwa chitetezo sikunasinthe, kumapangitsa kuti magwiridwe antchito azikhala bwino.
Kukana kwapadziko lonse pamatembenuzidwe a AC/DC kumakwaniritsa kufunikira kwa ma adapter amphamvu komanso magetsi pamakompyuta ndi matelefoni.Pamapangidwe amagetsi amagetsi, kugwiritsa ntchito mphamvu kwanthawi zonse kwachepetsedwa mpaka 1W, ndipo mphamvu zamagetsi zitha kuwonjezeka mpaka 90%.Kuti muchepetse kugwiritsa ntchito mphamvu kwanthawi yayitali, matekinoloje atsopano opangira IC ndi zopambana pamapangidwe ochepera amagetsi amafunikira.
