1.Switching Regulators ke eng:
Voltage regulator ke sesebelisoa se etsang hore motlakase o tsoang o tsitsitse mme o na le potoloho ea motlakase oa motlakase, potoloho ea taolo le enjene ea servo.Ha motlakase o kenang kapa mojaro o fetoha, disampole tsa potoloho ea taolo ea taolo, e bapisa le ho holisa, ebe e khanna koloi ea servo ho potoloha e le hore boemo ba brashi ea khabone ea taolo bo fetohe.E boloka motlakase oa tlhahiso o tsitsitse ka ho fetola karo-karolelano ea li-coil.
The switching regulator e sebelisetsoa ho hlahisa motlakase oa tlhahiso ka ho laola transistor hore e fetole pakeng tsa boemo ba ON, le OFF mmuso le likarolo tsa polokelo ea matla (li-capacitor le li-inductors) ho boloka motlakase o tsitsitse.E fetoloa ka ho fetola nako ea ho fetola nako ho latela mehlala ea maikutlo a motlakase o tsoang.

Ho ea ka mofuta o fapaneng oa tlhahiso ea molaoli, molaoli ka kakaretso o arotsoe ka AC regulator (AC voltage stabilization power supply) le DC regulator (DC voltage stabilization power supply) mekhahlelo e 'meli.
AC voltage regulator: voltage regulator e na le mashome a maholo ho isa ho likete tsa kilowatts tsa AC voltage regulator, ke phepelo ea matla a maholo a liteko le a indasteri, a lisebelisoa tsa bongaka.Ho boetse ho na le lilaoli tse nyane tsa motlakase tsa AC tsa li-watts tse 'maloa ho isa ho li-kilowatts tse' maloa, tse etselitsoeng lilaboratori tse nyane kapa lisebelisoa tsa lapeng ho fana ka matla a boleng bo holimo.
Batsamaisi ba DC: Ho ea ka boemo ba ts'ebetso ea tube ea tokiso, balaoli ba DC hangata ba arotsoe ka mekhahlelo e 'meli: li-ware and switching regulators.Switching regulator rectifier, smoothing circuit e na le mofuta oa ho kenya capacitor le mefuta e 'meli ea coil ea choke, e hloka ho feto-fetoha le maemo ho latela mokhoa oa ho e sebelisa.Mofuta oa ho kenya li-coil o sebelisoa ho li-switching regulator, ha mofuta oa ho kenya li-capacitor o sebelisoa ho li-switching regulator.
