Decoupling capacitors yog siv txhawm rau lim tawm qhov hluav taws xob tawm hluav taws xob thiab dhau los ntawm tsuas yog DC tivthaiv ntawm lub teeb liab. Lub tswv yim yog siv lub capacitor nyob rau hauv xws li ib txoj kev uas nws shunts, los yog absorbs lub suab nrov ua lub DC teeb liab kom du li sai tau.
Vim li cas decoupling capacitor siv?
Ib tug decoupling capacitor, kuj hu ua ib tug bypass capacitor, ua raws li ib yam ntawm lub zog reservoir. … Yog hais tias qhov input voltage poob, ces ib tug decoupling capacitor yuav muaj peev xwm muab lub hwj chim txaus rau ib tug IC kom lub voltage ruaj khov.
Kuv puas xav tau cov capacitors decoupling?
Zoo heev txhua tus IC yuav tsum muaj lub capacitor decoupling. Yog tias tsis muaj dab tsi tau teev tseg los ntawm daim ntawv teev npe, qhov tsawg kawg nkaus, muab 0.1 uF ceramic cap ze ntawm lub hwj chim tus pin ntawm IC, ntsuas tsawg kawg ob zaug ntawm qhov hluav taws xob uas koj siv. Ntau yam yuav xav tau ntau dua capacitance ntawm cov tswv yim.
Lub hom phiaj ntawm kev siv cov khoom siv hluav taws xob hauv PCB yog dab tsi?
Lub decoupling ua haujlwm raws li a reservoir thiab ua nyob rau hauv ob txoj hauv kev kom stabilize qhov voltage. Thaum qhov voltage nce siab tshaj tus nqi ntsuas, lub decoupling capacitor absorbs cov nqi ntau dhau. Lub caij no, lub decoupling capacitor tso tawm cov nqi thaum lub zog poob kom ntseeg tau tias cov khoom ruaj khov.
Koj tso lub tshuab hluav taws xob nyob qhov twg?
Decoupling capacitors yuav tsum muab tso ze li sai tau rau qhov chaw rau lub teeb liab yogdecoupled. Qhov no txhais tau hais tias ntawm tus pin rau ICs thiab ze ntawm lub connector rau kev tawm tswv yim thiab tawm teeb liab. Txhawm rau tshem tawm LF transients los ntawm kev tawm tswv yim thiab cov teeb liab tawm, lub capacitor yuav tsum muab tso rau hauv cov kab nrog cov kab.

Dab tsi yog qhov txawv ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob?
Gramophone: Txhua lub suab kaw suab, lossis cov cuab yeej ua si yav dhau los-cov suab kaw, tshwj xeeb tshaj yog tias nws siv lub tiaj tiaj tiaj. Phonograph: Txhua lub suab kaw suab, lossis cov cuab yeej siv rau kev ua si cov suab uas tau kaw dhau los, tshwj xeeb tshaj yog tias nws siv lub tog raj kheej tig.
Puas yog lub tshuab hluav taws xob xav tau lub tshuab hluav taws xob?
Diesels tsis xav tau lawv - pob tseg li qub / tshuab tawm li qub yog tsim los rau qhov chaw nruab nrab ntawm lub turbo thiab lub throttle. Nyob rau hauv ib tug petrol engine, ntawm siab boost, thaum koj snap lub throttle kaw lub turbo tseem tig.
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
Puas yog lub tshuab hluav taws xob puas muaj lub tshuab hluav taws xob?
Vim li cas lub tshuab hluav taws xob sab hauv combustion yuav tsum tsis muaj lub tshuab hluav taws xob los ua kom cov roj tsis zoo li roj av? Spark plugs yog siv nyob rau hauv cov roj cav mus ignite cov pa roj sib tov whereas nyob rau hauv diesel engines lub xub ntiag ntawm lub txim plugs yog tsis tsim nyog.
