Kev Siv Tshuab Tshiab thiab Kev Txhim Kho ntawm DC Fais Fab Khoom
Nrog rau txoj kev loj hlob sai ntawm kev siv tshuab hluav taws xob thiab kev sib txuas lus kev lag luam, daim ntawv thov ntawm cov khoom siv hluav taws xob hloov hluav taws xob tau dhau los ua ntau dua. Kev txhim kho txuas ntxiv ntawm kev hloov pauv ntau ntxiv ua kom zoo dua qhov kev ua tau zoo ntawm kev hloov hluav taws xob, nrog kev sib koom ua ke ntau dua, kev siv hluav taws xob qis dua, kev siv hluav taws xob yooj yim dua, thiab kev lag luam txhim khu kev qha, uas yog cov kev taw qhia ntawm kev hloov hluav taws xob hloov khoom siv. Tam sim no, cov khoom siv hluav taws xob hloov hluav taws xob ntau tau siv dav hauv ntau lub chaw nres tsheb microwave ntawm xov tooj cua thiab TV hauv peb lub xeev. Raws li qhov no, peb yuav sib piv cov khoom siv hluav taws xob ib txwm muaj nrog cov khoom siv hluav taws xob hloov hluav taws xob niaj hnub no los qhia cov thev naus laus zis tshiab thiab qhov zoo ntawm cov khoom siv hluav taws xob ntau zaus.
1. Lub hauv paus ntsiab lus ntawm high-frequency switching fais fab mov
High zaus hloov rectifiers feem ntau ua ntej hloov AC fais fab ncaj qha los ntawm diode rectification thiab lim rau DC lub zog, thiab tom qab ntawd hloov mus rau hauv high-frequency AC zog los ntawm kev hloov hluav taws xob. Tom qab raug rho tawm los ntawm lub tshuab hluav taws xob ntau zaus, lawv tau rov qab los ntawm diode high-frequency rectification thiab inductor capacitor filtering ua ntej tso tawm.
Main Circuit Court
Tag nrho cov txheej txheem ntawm kev tawm tswv yim thiab tso tawm los ntawm AC lub zog hluav taws xob, suav nrog:
(1) Input filter: Nws muaj nuj nqi yog lim tawm cov clutter uas twb muaj lawm nyob rau hauv lub hwj chim daim phiaj, thaum tseem tab tom cuam tshuam cov lus tawm tswv yim ntawm cov generated clutter rau pej xeem lub hwj chim daim phiaj.
(2) Rectification thiab filtering: ncaj qha rectifying AC fais fab mov ntawm daim phiaj fais fab mus rau smoother DC fais fab mov thiab muab ruaj khov DC fais fab rau lub hwj chim kho Circuit Court.
(3) Kev kho lub zog muaj zog: nyob nruab nrab ntawm rectifier filtering thiab inverter, txhawm rau tshem tawm cov pa phem tam sim no los ntawm rectifier circuits thiab txo cov hluav taws xob tsis zoo los txhim kho lub zog.
(4) Inversion: Hloov lub zog DC rectified rau hauv high-frequency AC zog, uas yog ib feem ntawm lub high-frequency switching fais fab mov. Qhov ntau zaus, qhov sib piv me me ntawm ntim, qhov hnyav, thiab cov zis hluav taws xob.
(5) Tso zis rectification thiab filtering: Muab ruaj khov thiab txhim khu kev qha DC fais fab mov raws li qhov yuav tsum tau ua.
tswj Circuit Court
Ntawm ib sab, cov qauv raug coj los ntawm qhov kawg tso zis, piv nrog cov txheej txheem teeb tsa, thiab tom qab ntawd lub inverter yog tswj los hloov nws cov zaus lossis mem tes dav kom ua tiav cov zis ruaj khov. Ntawm qhov tod tes, raws li cov ntaub ntawv muab los ntawm kev ntsuas Circuit Court thiab txheeb xyuas los ntawm kev tiv thaiv Circuit Court, tswj Circuit Court yog muab los muab ntau yam kev tiv thaiv kev ntsuas rau tag nrho lub tshuab.
Kev kuaj xyuas Circuit Court
Ntxiv nrog rau kev muab ntau yam kev ua haujlwm tsis zoo hauv kev tiv thaiv Circuit Court, ntau cov ntaub ntawv ntsuas ntsuas kuj tau muab rau kev soj ntsuam thiab kaw los ntawm cov neeg ua haujlwm hauv lub luag haujlwm.
Pab txhawb zog
Muab ntau yam khoom siv hluav taws xob (AC thiab DC qhov hluav taws xob ntawm ntau qib) xav tau rau kev ua haujlwm ntawm txhua qhov hluav taws xob ntawm lub tshuab hloov hluav taws xob nws tus kheej.
