Hloov Fais Fab Transformer Function thiab Classification
Rau transformers, lawv yog cov khoom siv uas tuaj yeem hloov hluav taws xob. Peb feem ntau hu nws lub hwj chim transformer. Tab sis qhov sib txawv ntawm kev hloov hluav taws xob hloov pauv thiab lwm yam hloov pauv yog tias nws muaj qhov hloov pauv ntxiv piv rau cov hloov pauv tsis tu ncua. Nyob rau hauv txoj kev no, tus kheej-excited intermittent oscillator yog tsim, uas tuaj yeem kho cov input DC voltage rau hauv high-frequency mem tes voltage thiab tso zis.
Ntxiv nrog rau cov haujlwm saum toj no, cov khoom no kuj muaj lub luag haujlwm tseem ceeb dua, uas yog kev sib kis thiab kev hloov pauv ntawm lub zog. Nyob rau hauv lub flyback Circuit Court, thaum peb tig rau lub switching transistor, tus coj transformer converts hluav taws xob zog mus rau hauv ib tug sib nqus teb thiab khaws cia rau ua. Thaum peb disconnect lub hloov raj, lub magnetic teb kuj yuav hloov mus rau hauv hluav taws xob lub zog.
Yog li yuav ua li cas thiaj li ua tiav hauv pem hauv ntej circuits? Ua ntej, thaum peb ua qhov hloov pauv hloov pauv, cov khoom siv hluav taws xob cuam tshuam yuav raug siv los muab cov khoom thauj ncaj qha, thiab tib lub sijhawm, lub zog yuav raug khaws cia los ntawm inductance. Thaum peb disconnect lub hloov raj, hluav taws xob lub zog yuav raug xa mus rau lub load los ntawm lub zog cia inductor.
Thaum kawg, lub zog hloov hluav taws xob hloov pauv tuaj yeem hloov pauv qhov hloov pauv DC voltage, tso cai rau nws tso tawm ntau qhov ntau thiab tsawg ntawm cov hluav taws xob tsawg. Peb tau tham txog nws txoj haujlwm tiav lawm, yog li nws qhov kev faib tawm yog dab tsi?
Feem ntau hais lus, muaj ob hom kev hloov hluav taws xob hloov hluav taws xob, uas yog ib qho excitation thiab ob chav excitation. Cov qauv ntawm ob qhov kev faib tawm no txawv, thiab lawv cov qauv kev ua haujlwm kuj txawv heev. Ib leeg mem tes tuaj yeem nkag mus rau unipolar pulses thiab tso tawm rau pem hauv ntej thiab thim rov qab voltages; Qhov txawv ntawm dual pulse thiab bipolar mem tes yog tias feem ntau ntawm lawv tso zis bipolar mem tes voltage.
Los ntawm cov ntawv sau saum toj no, ntau tus phooj ywg tau nkag siab qee yam ntawm transformers. Rau kev hloov hluav taws xob hloov hluav taws xob, nws tsis yog hais txog kev ntxiv qhov sib txawv ntawm lub zog hloov pauv, tab sis kuj ua rau qee qhov ntawm lawv cov kev siv ntau dua. Tsis tas li ntawd, rau qee qhov kev siv tshwj xeeb, lub zog hloov hluav taws xob nrog cov cuab yeej no tuaj yeem hloov hluav taws xob raws li qhov xav tau, ua tiav cov txiaj ntsig ntawm kev ua tau raws li ntau hom kev xav tau ntawm qhov hluav taws xob hauv kev lag luam.
