Kev piav qhia ntawm kev cuam tshuam sab nraud hauv cov khoom siv hluav taws xob hloov pauv
Kev cuam tshuam sab nraud rau lub zog hloov hluav taws xob tuaj yeem muaj nyob hauv "hom hom" lossis "hom txawv". Hom kev cuam tshuam tuaj yeem sib txawv los ntawm lub sijhawm luv luv mus rau qhov poob tag nrho. Nws kuj muaj xws li voltage variations, zaus variations, waveform distortion, tsis tu ncua suab nrov los yog clutters, thiab transients.
Qhov tseem ceeb tshaj plaws uas tuaj yeem kis tau los ntawm cov khoom siv hluav taws xob thiab ua rau cov khoom puas tsuaj lossis cuam tshuam rau nws txoj haujlwm yog cov hluav taws xob ceev ceev hloov pauv cov pa taws thiab surge shock yoj, thaum cov hluav taws xob hluav taws xob thiab lwm yam cuam tshuam ntev npaum li cov khoom siv hluav taws xob nws tus kheej tsis ua. tsim kev co, tso zis voltage poob thiab lwm yam tshwm sim, nws yuav tsis ua rau lub hwj chim mov los ntawm kev cuam tshuam rau cov khoom siv fais fab.
Lub zog hloov hluav taws xob hloov hluav taws xob: lub zog hloov hluav taws xob yog lub hauv paus ntawm kev hloov hluav taws xob tswj hluav taws xob, nws ua kom muaj qhov dav dua thiab muaj kev sib haum xeeb. Cov khoom tseem ceeb uas ua rau qhov kev cuam tshuam pulse no yog:
1) switching tube switching tube thiab nws lub dab dej kub thiab lub plhaub thiab lub hwj huam mov ua rau hauv qhov kev faib tawm, thaum lub raj xa hluav taws xob ntws los ntawm cov mem tes loj tam sim no (yoj lub voj voog loj), lub waveform muaj ntau cov khoom siv ntau zaus; Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob hloov hluav taws xob tsis zoo xws li hloov cov raj xa hluav taws xob, xws li lub sijhawm cia, cov theem tso tawm ntawm cov tam sim no loj, hloov lub rectifier diode rov qab lub sij hawm, yuav ua rau ib qho luv luv Circuit Court tam sim no, ua rau muaj kev cuam tshuam loj heev. loj luv luv-circuit tam sim no, nyob rau hauv tas li ntawd, lub load ntawm lub switching tube yog ib tug high-frequency transformer los yog cia inductor, nyob rau hauv lub instant ntawm switching tube conduction, lub transformer thawj zoo nkaus li yog ib tug loj inrush tam sim no, uas ua rau lub suab nrov nrov.
2) high-frequency transformer switching fais fab mov transformer, siv raws li kev sib cais thiab transformer, tab sis vim to inductance, yuav tsim electromagnetic induction suab; Nyob rau tib lub sij hawm, nyob rau hauv lub high-frequency mob ntawm lub transformer txheej ntawm distribution capacitance yuav yog thawj sab ntawm lub high-harmonic suab nrov mus rau lub thib ob sab, thiab lub transformer mus rau lub plhaub ntawm lub distribution capacitance los ua ib tug high-zoo suab. txoj kev zaus, yog li ntawd cov electromagnetic teb generated nyob ib ncig ntawm lub transformer yog feem ntau yuav tsum tau ua ke mus rau lwm yam ua rau lub suab nrov.
3) rectifier diode thib ob sab rectifier diode siv los ua lub tshuab hluav taws xob ntau zaus, vim yog lub sijhawm rov qab los, feem ntau xa mus rau tam sim no tsub zuj zuj ntawm cov nqi ntxiv ntawm qhov rov qab voltage tsis tuaj yeem tshem tawm tam sim ntawd (vim muaj cov neeg nqa khoom, muaj kev khiav dej num). Thaum qhov kev thim rov qab tam sim no thaum txoj kab nqes loj dhau lawm, ntws los ntawm lub kauj inductance ua rau muaj qhov sib txawv ntawm qhov hluav taws xob, nyob rau hauv lub transformer leakage inductance thiab lwm yam kev faib tawm yuav ua rau muaj kev cuam tshuam ntau zaus, qhov zaus tuaj yeem ncav cuag kaum tawm MHz.
4) Capacitors, inductors thiab cov xov hlau hloov hluav taws xob vim ua haujlwm ntawm ntau zaus, yuav ua rau cov yam ntxwv ntawm cov khoom siv tsawg zaus hloov, uas ua rau lub suab nrov.
