Vim li cas qhov voltage stabilized fais fab mov dav siv?
Muaj ntau ntau txoj hauv kev rau cov khoom siv hluav taws xob tswj, suav nrog DC tswj cov khoom siv hluav taws xob thiab AC tswj cov khoom siv hluav taws xob raws li hom tso zis hluav taws xob; Raws li txoj kev sib txuas ntawm qhov voltage regulator circuit thiab load, muaj series voltage regulators thiab parallel voltage regulators; Raws li lub xeev ua hauj lwm ntawm lub hloov raj, muaj linear stabilized fais fab mov thiab hloov stabilized fais fab mov; Raws li hom Circuit Court, muaj cov khoom siv hluav taws xob ruaj khov yooj yim thiab cov lus tawm tswv yim ruaj khov cov khoom siv hluav taws xob, thiab lwm yam.
Qhov zoo thiab qhov tsis zoo ntawm kev hloov hluav taws xob ruaj khov
qhov zoo:
Piv nrog "series hloov hom tswj fais fab mov", "hloov hom tswj fais fab mov" yog ntau npaum thiab txuag hluav taws xob; Muaj peev xwm ua tau zoo rau kev hloov pauv hauv cov khoom siv hluav taws xob; Dav adjustable ntau yam ntawm cov zis voltage; Ib lub raj hloov tau yooj yim tau txais ntau yam khoom siv hluav taws xob nrog cov qib sib txawv; Nws muaj ntau yam zoo xws li qhov me me thiab lub teeb yuag, thiab yog siv dav.
(1) Kev siv hluav taws xob tsawg thiab kev ua haujlwm siab
(2) Me me, lub teeb yuag
(3) Kev tswj hwm qhov dav dav
(4) Kev ua tau zoo ntawm kev lim dej tau zoo heev, uas ua rau muaj kev txo qis hauv lub peev xwm thiab ntim ntawm cov lim lim capacitor.
(5) Cov ntaub ntawv sib txawv thiab sib txawv
Lub hauv paus ntsiab lus ua haujlwm: Tom qab kho thiab lim, DC qhov hluav taws xob yog muab los ntawm R1 mus rau lub hauv paus ntawm txoj kev tswj lub raj, ua rau kev tswj cov raj xa hluav taws xob. Thaum V1 yog conductive, qhov voltage dhau los ntawm RP thiab R2 ua V2 conductive, thiab ces V3 kuj conductive. Lub sijhawm no, cov emitter thiab cov khoom siv hluav taws xob ntawm V1, V2, thiab V3 tsis hloov lawm (lawv txoj haujlwm yog ib yam nkaus li ntawm lub tshuab hluav taws xob hluav taws xob). Kho RP tuaj yeem tau txais qhov tso zis ruaj khov, thiab qhov sib piv ntawm R1, RP, R2, thiab R3 txiav txim siab tus nqi hluav taws xob los ntawm qhov hluav taws xob no.
Qhov sib txawv ntawm linear tswj fais fab mov thiab switching fais fab mov
Switching stabilized fais fab mov ua tiav voltage hloov dua siab tshiab thiab stabilization los ntawm converting DC mus rau high-frequency pulses thiab ces ua electromagnetic transformation. Cov kab hluav taws xob tswj hluav taws xob yog qhov hloov kho tau yooj yim txuas ncaj qha rau hauv series los faib cov khoom siv hluav taws xob DC, ua tiav qhov hloov pauv hluav taws xob thiab kev tswj hwm, qhov tseem ceeb sib npaug rau kev sib txuas ntawm qhov sib txawv ntawm cov resistor hauv series.
Switching stabilized fais fab mov muaj kev ua haujlwm siab thiab tuaj yeem siv rau ob qho tib si boosting thiab txo qis voltage. Linear tswj fais fab mov tuaj yeem txo qhov voltage thiab muaj kev ua haujlwm tsawg. Hloov cov khoom siv hluav taws xob tswj tau tuaj yeem tsim muaj kev cuam tshuam ntau zaus, thaum cov khoom siv hluav taws xob linear tswj tsis muaj kev cuam tshuam.
