Sui Pule Faatonu
1. O le a le Sui Pule Faatonu:
O le voltage regulator o se masini e faʻamautu ai le voluma faʻapipiʻi ma e aofia ai le eletise eletise, se taʻavale faʻatonutonu, ma se afi servo.Pe a suia le voltage sao poʻo le uta, e faʻataʻitaʻi e le pule faʻatonutonu faʻataʻitaʻiga, faʻatusatusa ma faʻateleina, ona faʻaosoina lea o le afi servo e sui ina ia suia le tulaga o le pulumu kaponi a le pule.E fa'atumauina le malosi o le gaosiga e ala i le otometi ona fetu'una'i le fua fa'atatau o le li'o.
E fa'aaogaina le fa'atonutonu suiga e fa'atupuina ai le voluma e ala i le fa'atonutonuina o le transistor e fesuia'i i le va o le ON state, ma le OFF state ma fa'atasi ai ma vaega e teu ai le malosi (capacitors ma inductors) e fa'amautu ai le voltage.E fetuutuunai e ala i le fetuutuunai o le taimi fesuiaʻi e tusa ai ma faʻataʻitaʻiga faʻataʻitaʻiga o le voltage gaosiga.
Folasaga galuega
O le voltage regulator o se ituaiga eletise sapalai eletise poʻo mea faʻapipiʻi eletise e mafai ona otometi ona fetuutuunai le voluma gaosiga.O le matafaioi a le voltage regulator o le fesuisuiai ma e le oʻo atu i manaʻoga o mea eletise e faʻamautu ai le eletise tuʻuina atu i lona tulaga tau faʻatulagaina ina ia mafai ai e le tele o taʻavale poʻo mea eletise ona galue masani i le voltage galue.
Vaaiga o le talosaga
O le voltage regulator e mafai ona faʻaaogaina lautele i pisinisi faʻapisinisi ma mining, suauʻu fanua, nofoaafi, nofoaga faufale, aʻoga, falemaʻi, suʻesuʻega faʻasaienisi, ma isi nofoaga e manaʻomia ai le faʻamautuina o le eletise.Fa'apena fo'i fa'afetaui i komepiuta fa'akomepiuta, masini masini sa'o, komipiuta tomography (CT), meafaigāluega sa'o, masini su'ega, moli si'i, masini fa'aulufale mai, laina gaosiga, ma isi mea faigaluega.E le gata i lea, o le voltage regulator e talafeagai foi mo le maualalo poʻo le maualuga o le eletise tuʻuina atu, felafolafoaiga i le pito o le laina maualalo-voltage tufatufaina o tagata faʻaoga, ma suiga o uta i mea eletise.O le voltage regulator e sili ona talafeagai mo manaoga maualuga uma o le grid waveform voltage stabilization o nofoaga eletise.E mafai ona fa'afeso'ota'i le mana maualuga e fa'amalieina le mana fa'atonu i le fa'amama, hydraulic, ma afi laiti.
Fa'avasegaga
E tusa ai ma le natura eseese o le gaioiga a le pule faʻatonu, e masani ona vaevaeina le pule faʻatonutonu i le AC regulator (AC voltage stabilization power supply) ma le DC regulator (DC voltage stabilization power supply) lua vaega.
AC voltage regulator: voltage regulator e tele sefulu i le afe o kilowatts o AC voltage regulator, o le tuʻuina atu o faʻataʻitaʻiga tele ma alamanuia, mana galuega meafaigaluega faafomai.O lo'o iai fo'i la'ititi la'ititi la'ititi o le AC o nai watts i nai kilowatts, ia e mo fale su'esu'e laiti po'o meafale e maua ai le malosi maualuga.
DC regulators: E tusa ai ma le tulaga o loʻo faʻaogaina le faʻaogaina o le paipa, o le DC regulators e masani ona vaevaeina i ni vaega se lua: ware ma fesuiaʻi tulafono faatonutonu.Switching regulator rectifier, smoothing circuit o loʻo i ai se capacitor input type ma choke coil input type two types, e manaʻomia ona fetuutuunai e tusa ai ma le fesuiaiga o le auala e faʻaogaina ai le faʻaogaina.O le ituaiga fa'aogaina o le coil coil e fa'aaogaina i le fa'asolo i lalo fa'atonutonu, a'o le fa'aogaina o le capacitor o lo'o fa'aogaina i le la'asaga i luga fa'atonutonu suiga.
O lenei oloa o se fa'aliliuga fa'asaga i lalo.
