Yuav ua li cas kom tsis txhob cuam tshuam hauv Kev Hloov Cov Khoom Siv Hluav Taws Xob
Cov khoom siv hluav taws xob ruaj khov yog cov khoom siv hluav taws xob uas tuaj yeem muab cov khoom ruaj khov AC lossis DC lub zog rau lub nra, suav nrog ob pawg: AC stabilized fais fab mov thiab DC stabilized fais fab mov. Thaum muaj qhov hloov pauv sai sai hauv daim phiaj hluav taws xob lossis kev thauj khoom, cov khoom siv hluav taws xob tswj hwm yuav them rau qhov voltage amplitude ntawm cov lus teb ceev ntawm 10-30ms, ua rau nws ruaj khov nyob rau hauv ± 2 feem pua.
Switching tswj fais fab mov yog ib yam tshiab ntawm lub hwj chim mov. Nws muaj qhov zoo ntawm kev ua haujlwm siab, lub teeb yuag, muaj peev xwm nce lossis txo qhov voltage, thiab lub zog tso zis siab. Txawm li cas los xij, vim lub Circuit Court ua haujlwm hauv lub xeev qhib / tawm, lub suab nrov kuj yog siab heev. Siv cov duab kos hauv qab no, peb yuav piav qhia luv luv txog kev ua haujlwm ntawm lub kauj ruam-down switching fais fab mov. Raws li pom nyob rau hauv daim duab, lub Circuit Court yog tsim los ntawm hloov K (triode los yog Field-effect transistor nyob rau hauv lub tiag tiag Circuit Court), Flyback diode D, lub zog cia inductance L, lim capacitor C. Thaum lub switching kaw, lub hwj chim mov muab lub thauj khoom los ntawm kev hloov K thiab inductor L, thiab khaws qee lub zog hluav taws xob hauv inductor L thiab capacitor C.
Thaum lub switching tswj fais fab mov ua hauj lwm, lub switching triode thiab lub Flyback diode (los yog lwm switching triode) yeej ib txwm qhib los yog offal hloov. KQ thiab KD tsis yog cov khoom siv zoo tagnrho, thiab kev hloov pauv ntawm ob lub xeev yuav siv sijhawm qee lub sijhawm, uas ua rau muaj kev cuam tshuam loj heev. Thaum lub sijhawm hloov pauv hauv lub xeev, qhov kev hloov pauv tsis ua tiav, thaum lub sijhawm txiav tawm tsis muaj lub sijhawm txiav tawm. Muaj ib txoj hauv kev ncaj qha los ntawm cov khoom siv hluav taws xob mus rau hauv av, tsim cov khoom siv tam sim no. Qhov tam sim no muaj feem xyuam nrog rau yam xws li qhov sib txawv ntawm tam sim no Imax thaum lub transistor hloov mus thiab tam sim no Icmin thaum nws tawm, nrog rau lub sij hawm ntawm ib txhij conduction ntawm keyboards KQ thiab KD. Vim yog qhov cuam tshuam ntawm kev faib hluav taws xob hauv Circuit Court, lub nplhaib oscillation tshwm sim ntawm lub waveform.
Lub tshuab hluav taws xob tswj hluav taws xob radiates cuam tshuam rau hauv qhov chaw thaum ua haujlwm. Qib ntawm cov suab nrov radiated yog inversely proportional rau qhov kev ncua deb ntawm cov hluav taws xob qhov chaw. Feem ntau, xaim tuaj yeem ua tiav ntawm qhov deb ntawm 5cm. Yog tias nws tsis raug tso cai los ntawm cov txheej txheem, kev tiv thaiv yuav tsum tau ntxiv. Lub zog hluav taws xob muaj zog yog tsim nyob ib ncig ntawm lub zog hluav taws xob cov kab hluav taws xob, thiab txhawm rau txo cov hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob thiab cov khoom siv tawm, lawv yuav tsum tau khaws cia tseg.
