Hom latch (kev tiv thaiv kev kaw haujlwm) thiab hom hiccup (pib- rov qab) yog ob qho kev ua txhaum ntau tshaj plaws hauv kev hloov cov khoom siv hluav taws xob. Lawv qhov sib txawv tseem ceeb nyob ntawm seb tib neeg kev cuam tshuam puas yuav tsum tau rov ua haujlwm tom qab qhov kev ua txhaum raug tshem tawm.
Hauv qab no yog cov ncauj lus kom ntxaws sib piv:
1. Latch Hom (Kev Tiv Thaiv Kev Tiv Thaiv)
Lus Txhais: Thaum muaj kev txhaum (xws li, overvoltage, overcurrent, luv Circuit Court, overtemperature) raug kuaj pom, lub hwj chim tswj IC tam sim ntawd nres PWM tso zis, kaw lub hwj chim mov tag, thiab tseem nyob rau hauv no tawm lub xeev kom txog rau thaum ib tug sab nraud mob (xws li, lub hwj chim cycling) intervenes.
Action logic: Tshawb xyuas qhov txhaum → kaw tam sim ntawd → Tswj lub xeev xauv.
Cov kev mob rov qab: Lub zog tawm tswv yim yuav tsum raug txiav tawm (tshwj xeeb los yog tua lub ntsiab hloov), tos kom cov capacitors sab hauv tawm (ob peb vib nas this mus rau kaum vib nas this), thiab tom qab ntawd rov siv lub zog rov ua haujlwm li qub.
Qhov zoo:
Kev nyab xeeb siab: Nyob rau hauv cov ntaub ntawv ntawm overvoltage los yog luv luv Circuit Court, latch hom tiv thaiv rov pib dua kev sim, tsis txhob muaj kev puas tsuaj rau loads (xws li, CPUs, precision instruments) los ntawm repetitive tam sim no surges, thiab tiv thaiv arcing / cua sov ntawm qhov txhaum taw tes uas yuav ua rau hluav taws.
Qhia meej qhov txhaum: tsuav yog lub hwj chim latched, nws qhia tau hais tias qhov txhaum tseem muaj los yog muaj qhov txhaum loj tshwm sim, ua teeb meem yooj yim rau cov neeg ua haujlwm tu.
Qhov tsis zoo:
Cov neeg siv kev paub tsis zoo: Rau kev cuam tshuam ib ntus (xws li, xob laim, kub- ntsaws lub nra hnyav), lub zog hluav taws xob tsis zoo li qub; tus neeg siv yuav tsum manually unplug/replug. Hauv cov khoom siv embedded, qhov no yuav ua rau lub xeev "tsis tseeb tuag".
Cov ntawv thov sib xws: High-kawg PC fais fab mov (ATX), cov khoom siv kho mob siv hluav taws xob, cov khoom siv fais fab, roj teeb chargers (latch tom qab them tag nrho yuav tsum tau rov ua dua tshiab).
2. Auto-Rov qab (Hiccup Mode)
Lus Txhais: Thaum kuaj pom qhov txhaum, lub hwj huam mov kaw tawm cov zis. Tom qab lub sijhawm "so" (feem ntau pua ntawm milliseconds mus rau ob peb feeb), nws cia li sim rov pib dua. Yog tias qhov txhaum tau raug tshem tawm, kev ua haujlwm ib txwm rov pib dua; yog tias qhov txhaum tseem nyob, nws kaw dua, rov ua lub voj voog.
Action logic: Tshawb xyuas qhov txhaum → kaw → Tos (pw tsaug zog) → Pib- rov pib dua → Tshawb xyuas qhov txhaum (yog tias tsis tau tshem tawm, rov ua dua).
Cov xwm txheej rov qab: Tsis xav tau kev cuam tshuam tib neeg. Sai li qhov xwm txheej uas cuam tshuam kev tiv thaiv ploj mus (xws li, luv Circuit Court tshem tawm, kub poob, overloaded ntaus ntawv unplugged), lub hwj chim mov yuav rov qab mus rau ib txwm ua hauj lwm nyob rau hauv lub tom ntej no restart voj voog.
Qhov zoo:
Kev hloov pauv siab: Zoo tagnrho rau ib puag ncig uas muaj qhov tsis raug ncua sijhawm (piv txwv li, lub cev muaj zog thaum lub sijhawm pib, kub- cov khoom siv hloov pauv, luv luv).
Tus nqi tu qis: Hauv cov chaw taws teeb lossis cov khoom siv tsis muaj neeg saib xyuas, nws pib- rov qab tiv thaiv lub zog hluav taws xob los ntawm "txias" vim muaj kev cuam tshuam ib ntus, txhim kho qhov muaj nyob hauv.
Qhov tsis zoo:
Kev ntxhov siab ib ntus: Thaum lub sijhawm ua txhaum, cov khoom siv hluav taws xob pheej rov ua dua, ua rau qhov yuam kev (xws li, luv MOSFET, kev puas tsuaj) rau lub voj voog tam sim no, uas yuav ua rau qhov txhaum loj dua.
Lub zog nruab nrab qis: Hauv hom hiccup, txawm tias qhov siab tshaj plaws tam sim no yuav siab, lub voj voog qis heev ua rau lub zog nruab nrab qis, feem ntau tiv thaiv lub hwj chim ntawm nws tus kheej los ntawm overheating thiab hlawv tawm.
Cov ntawv thov: Xov tooj chargers, LED tsav tsheb, cov neeg siv khoom feem ntau - qib adapters, tsheb fais fab khoom siv.
Vim li cas cov neeg tsim qauv xaiv ntau hom?
Qhov kev xaiv tsuas yog nyob ntawm qhov xwm txheej ntawm qhov load:
Yog hais tias lub load yog kim thiab irreplaceable (xws li, CPU, kho mob cov cuab yeej, industrial robots): Latch hom yog yuav tsum tau. Nws pib- rov qab rov qab qhib / tawm kev caij tsheb kauj vab yog sib npaug rau "hluav taws xob poob siab" rov qab los rau qhov tseeb digital circuits, yooj yim ua rau kev ua yuam kev lossis lub cev puas tsuaj. Cov neeg tsim qauv nyiam qhov kev kaw kom tiav es tsis yog "convulsive" ua haujlwm.
Yog hais tias lub load yog capacitive, hloov tau, los yog portable (xws li, xov tooj, LED teeb, motors): Auto- rov qab yog feem ntau siv. Piv txwv li, thaum lub xov tooj charger luv luv -circuit, tus neeg siv tsuas yog unplugs thiab relugs lub xov tooj cable. Yog tias txhua qhov luv luv yuav tsum tau tshem tawm lub charger los ntawm lub qhov (socket) phab ntsa, cov neeg siv kev paub yuav txaus ntshai.
