Mphamvu Wonjezerani Kaperekedwe

makhalidwe mphamvu kotunga

Pali zingapo mphamvu kotunga mikhalidwe imene bwanji ntchito zawo:

Kutengeka:  The akusinthasintha DC linanena bungwe voteji ngati ntchito ya nthawi zonse mzere voteji, katundu, ndi yozungulira kutentha.

Mphamvu kuti:  magetsi A akhoza ntchito mu dongosolo kumene ayenera kupereka kudya zazikulu poyankha kusintha mphamvu katundu. Kuti akhoza kukhala ndi vuto la katundu microprocessors mkulu-liwiro ndi ntchito mphamvu kasamalidwe. Mu nkhani iyi, microprocessor akhoza kukhala mu mkhalidwe standby ndi pa lamulo ayenera kuyamba kapena kuzimitsa yomweyo, amene akusokoneza mkulu mafunde zazikulu ndi kudya mitengo limbikitsa pa magetsi. Kuti kuwaganizira microprocessor, mwa kundipatsako a linanena bungwe voteji ayenera limbikitsa kapena pansi mkati mwachindunji nthawi imeneyi, koma popanda overshoot kwambiri. 

Mwachangu:  alionse m'dzikoli pali wa linanena bungwe ndi athandizira mphamvu (mu peresenti), anayeza pa anapatsidwa katundu panopa ndi zinthu mwadzina mzere (Pout / Pin).

Holdup nthawi:  Nthawi imene chakudya mphamvu linanena bungwe voteji akhalabe mwa mfundo zotsatirazi imfa ya mphamvu athandizira.

Inrush panopa:  Peak yomweyo athandizira panopa kukopedwa ndi magetsi pa kutembenuka pa.

Mayiko miyezo:  Fotokozani zofunika chitetezo chakudya mphamvu ndi kololeka EMI (mu atomu kusokonezedwa) misinkhu. 

Kudzipatula:  Zamagetsi kulekana pakati athandizira ndi linanena bungwe la magetsi amayezedwa volts. A sanali akutali ali DC njira pakati athandizira ndi linanena bungwe la okwanira, koma lakutali mphamvu kotunga ntchito thiransifoma kuthetsa DC njira pakati athandizira ndi linanena bungwe.

Mzere lamulo:  Change mtengo wa DC linanena bungwe voteji chifukwa cha kusintha wopezeka athandizira voteji, chinaneneratu monga kusintha ± MV kapena ±%.

Katundu lamulo:  Change mtengo wa DC linanena bungwe voteji chifukwa cha kusintha katundu ku lotseguka-dera yokhala ndi oveteredwa linanena bungwe panopa, chinaneneratu monga kusintha ± MV kapena ±%.

Linanena bungwe phokoso:  Zimenezi zimachitika mu magetsi mu mawonekedwe a bursts kochepa mphamvu mkulu pafupipafupi. Phokoso chifukwa cha nawuza ndi lililonse la capacitances parasitic mkati magetsi pa mkombero opaleshoni ake. Matalikidwe ake ndi variable ndi mutha kumudalira katundu impedance, zosefera kunja, ndi momwe izo ziriri kayesedwe. 

Linanena bungwe voteji kokha:  Most power supplies have the ability to “trim” the output voltage, whose adjustment range does not need to be large, usually about ±10%. One common usage is to compensate for the dc distribution voltage drop within the system. Trimming can either be upward or downward from the nominal setting using an external resistor or potentiometer.

Zodziwitsa ndi mwachisawawa kupatuka (PARD): zapathengo zodziwitsa (ripple) kapena aperiodic (phokoso) kupatuka a mphamvu-kotunga linanena bungwe voteji ku mtengo wake mwadzina. PARD yafotokozedwera MV pachimake ndi nsonga kapena rms, pa bandiwifi yake.

Peak panopa:  The pazipita panopa kuti magetsi angapereke kwa nthawi yochepa. 

Peak mphamvu:  Mtheradi pazipita linanena bungwe mphamvu zimene magetsi zingabweretse popanda kuwononga. Ndi amangoona bwino kupitirira mosalekeza odalirika imapanga linanena bungwe mphamvu ndi ayenera kugwiritsidwa ntchito pokhapokha infrequently.

Mphamvu kotunga molumikiza:  yotsatana kutembenuka osinthasintha katundu mphamvu ukafunidwe mu kachitidwe ndi voltages angapo opaleshoni. Ndiko kuti, voltages ayenera kugwiritsidwa ntchito mu ndondomeko yeniyeni, mwinamwake dongosolo akhoza kuonongeka. Mwachitsanzo, kugwiritsa ntchito voteji woyamba ndipo akafika mtengo enaake, voteji yachiwiri ramped mmwamba, ndi zina zotero. Molumikiza ntchito mu n'zosiyana pamene mphamvu chikutha ngakhale sikukudziwika zambiri mochuluka za vuto ngati kutembenuka pa.

Akutali pa / kutali:  Izi m'malo masiwichi kutembenukira amapereka mphamvu osinthasintha. Mphamvu kotunga data-pepala specifications zambiri mwatsatanetsatane magawo DC kwa akumidzi pa / kutali, lonena za osinthasintha milingo mfundo zofunikira.

Akutali tanthauzo:  A lililonse mphamvu kotunga oyang'anira linanena bungwe ake voteji ndiponso kudyetsa gawo la ilo mmbuyo kwa chakudya kupereka voteji lamulo. Mu njira iyi, ngati linanena bungwe amamuchititsa adzauka kapena kugwa, ndemanga nthawi okwanira a linanena bungwe voteji. Komabe, kukhalabe linanena bungwe zonse pa katundu, ndi magetsi angamusiye kuyan'ana voteji pa katundu. Koma, kugwirizana kwa linanena bungwe chakudya mphamvu kwa katundu ndi kukaniza ndipo panopa likuyenderera mu iwo umabala voteji dontho kuti amalenga voteji kusiyana pakati pa linanena bungwe okwanira ndi katundu enieni. Pakuti lamulo mulingo woyenera, ndi voteji kudyetsedwa ku magetsi ayenera leni katundu voteji. Yobweretsa awiri (kuphatikiza ndi opanda) kutali kugwirizana tanthauzo kuwunika kwenikweni katundu voteji, gawo limene ndiye kudyetsedwa ku chakudya ndi voteji dontho laling'ono kwambiri chifukwa panopa mwa kugwirizana awiri kutali lingaliro ndi otsika. Motero, ndi voteji ntchito kwa katundu ndi Lamulo.

Ripple:  kuthetsa ndipo imathandiza zotsatira ndi kusinthitsa mphamvu okwanira ndi linanena bungwe mu Mac chigawo (ripple) kuti akukwera pa DC linanena bungwe ake. Ripple pafupipafupi ndi ena angapo yofunika ya Converter ndi kusinthitsa pafupipafupi, potsata pa mtunda Converter. Ripple zimakhalanso mulibe katundu panopa, koma zikhoza anatsika ndi sefa kunja capacitor.

Yotsatira:  Pamene ntchito katundu angapo mphamvu linanena bungwe limene zotuluka chimodzi kapena zingapo kutsatira wina ndi kusintha mu mzere, katundu, ndi kutentha, kuti aliyense amakhala chimodzimodzi njila linanena bungwe voteji, mkati mwachindunji kutsatira kulolerana, ndi ulemu kwa mtengo wamba.
