Dab tsi yog qhov sib txawv ntawm qhov hloov hluav taws xob muab khoom thiab hloov pauv?
Rau cov hloov pauv, lawv yog cov khoom siv ua tau uas tuaj yeem hloov hluav taws xob. Peb feem ntau hu nws lub zog hloov hluav taws xob. Tab sis qhov sib txawv ntawm lub tshuab hloov hluav taws xob hloov pauv thiab lwm yam kev hloov pauv hluav taws xob yog tias nws muaj lub raj hloov pauv ntxiv piv rau cov hloov pauv ib txwm. Nyob rau hauv txoj kev no, tus kheej zoo siab sib quas tau muaj oscillator yog tsim, uas tuaj yeem hloov kho cov ntaub ntawv DC voltage rau hauv cov tshuaj ntsuam high-zaus voltage thiab tawm nws.
Ntxiv rau cov haujlwm saum toj no, cov khoom lag luam no tseem muaj lub luag haujlwm tseem ceeb dua, uas yog qhov kis thiab hloov dua siab tshiab. Nyob rau hauv ib qho flyback Circuit, thaum peb tig rau ntawm hloov chaw trantor, cov hloov pauv hloov pauv lub zog hluav taws xob rau hauv kev sib nqus thiab cov khw muag khoom nws rau kev ua. Thaum peb disconnect lub hloov raj, lub tiaj sib nqus tseem yuav hloov mus rau hauv lub zog hluav taws xob.
Yog li nws ua li cas thiaj tau ua rau hauv qab ci? Firstly, thaum peb coj tus hloov pauv hloov pauv, cov tswv yim ntsig txog voltage yuav raug siv los ua kom ncaj qha rau cov thauj khoom, thiab tib lub sijhawm, lub zog yuav muab khaws cia los ntawm kev tsis pom tseeb. Thaum peb disconnect lub hloov raj, lub zog hluav taws xob yuav hloov mus rau lub thauj mus los ntawm lub zog cia Inductor.
Thaum kawg, lub zog hloov hluav taws xob kuj tseem yuav hloov pauv DC voltage, tso cai nws kom tawm ntau qhov ntau thiab tsawg ntawm cov hluav taws xob tsawg. Peb tau ua tiav kev sib tham txog nws txoj haujlwm, yog li nws cov kev cais tawm yog dab tsi?
Feem ntau hais lus, muaj ob yam sib txawv hloov hluav taws xob hloov hluav taws xob, uas yog ib qho kev zam dhau thiab ua kom tiav. Cov qauv ntawm ob qho kev faib tawm no sib txawv, thiab lawv cov ntsiab cai ua haujlwm kuj yog qhov sib txawv. Ib mem tes tau tawm tswv yim unipolar pulge thiab kuj tso zis rau pem hauv ntej thiab rov qab volasages; Qhov sib txawv ntawm cov mem tes thiab bipolar pulorse yog qhov uas feem ntau ntawm cov bipolar mulolar ntsuas hluav taws xob.
Los ntawm cov ntawv sau saum toj no, ntau tus phooj ywg tau txais ib qho kev nkag siab ntawm cov hloov pauv. Rau hloov hluav taws xob hloov hluav taws xob, nws tsis yog hais txog kev ntxiv lub zog hloov sib txawv, tab sis kuj ua qee qhov ntawm lawv cov ntawv thov ntau dua. Ib qho ntxiv, rau qee cov ntawv thov tshwj xeeb, cov hluav taws xob hloov nrog cov cuab yeej no tuaj yeem hloov cov txiaj ntsig ntau yam voltage yuav tsum muaj nyob rau hauv cov lag luam lag luam.
