Umatshini wokupakisha uvavanyo oludityanisiweyo lwesekethe, eyona nto iphambili kufuneka ibe nokulinganisa amanqaku aphambili ovavanyo.
Indlela ngokubanzi kukusebenzisa uvavanyo lwesixhobo yonke i-voltage yonyawo kunye nephini lokuxhathisa umhlaba, igalelo kunye nemveliso yombane, ukusetyenziswa kwamandla kunye negalelo / imveliso ye-waveform, kunye neziphumo zovavanyo ngokuchasene neeparamitha zesekethe ezidityanisiweyo eziqhelekileyo, zinokugweba isekethe edibeneyo ukuba ivavanywe. eqhelekileyo.
kwi
umatshini wokupakisha, i-microprocessors yesekethe edibeneyo esetyenziswayo, ifilimu eshinyeneyo edibeneyo yesekethe kunye nokutshintsha amandla ombane osebenzayo weamplifier IC.
Makhe sihlalutye oluneenkcukacha malunga nezi.
umatshini wokupakisha uvavanyo lwesekethe oludibeneyo kwisitshixo samanqaku ovavanyo lwesekethe edibeneyo.
1.
Isitshixo kwindawo yovavanyo lwesekethe edibeneyo ye-microprocessor
isitshixo kwindawo yovavanyo lwesekethe edibeneyo ye-microprocessor ubukhulu becala icala lonikezelo lwamandla e-VDD, UKUSETHWA, UKUSETHWA, i-crystal IN igalelo lophawu lokungcangcazela, i-Xor ye-crystal vibration isiphumo sophawu lokuphela kwegalelo, imveliso, kunye nezinye iisekethe.
uvavanyo lwe-intanethi ukulinganisa inqaku eliphambili lokumelana kunye nexabiso le-voltage kunye nesiqhelo sinokugweba isiphaluka esidibeneyo siqhelekileyo;
2.
Isitshixo sokutshintshela indawo yokuvavanya umbane we-IC
isitshixo ekutshintsheni umbane wombane we-IC indawo yokuvavanya ubukhulu becala i-Vc yokubona isiphelo segalelo, i-voltage, igalelo lokubona ngoku, i-pulse output, njl.
Uvavanyo lwe-intanethi lwalusetyenziselwa ukulinganisa i-voltage yesekethe edibeneyo kunye nokuchasana kwephini ngalinye, kwaye emva koko xa kuthelekiswa nedatha eqhelekileyo, njengomahluko omkhulu, kufuneka kwakhona ibe yinto enxulumene novavanyo, icandelo limiselwe phantsi kwemeko yesiqhelo, linokugweba isekethe edibeneyo yonakele.
Kwi-switch yesiphaluka edibeneyo yokutshintsha ityhubhu licandelo elingundoqo, ifilimu eyakhelwe-ngaphakathi yesekethe edibeneyo yentambo yokutshintsha amandla amakhulu xa ingalunganga ukuthandabuza ityhubhu yokutshintshela inokulinganiswa ngokutshintshela ityhubhu c, b, e kakhulu phakathi phambili kunye nokumelana nokubuyisela umva. emgwebeni.
3.
Indawo yovavanyo ye-IC yeamplifier engundoqo
isitshixo sendawo yovavanyo ye-IC yeamplifier yeamplifier ikakhulu ligalelo kunye nesiphumo.
Le ndawo yexabiso lombane omileyo iphezulu.
uvavanyo, i-multimeter ukuya kwi-dc yombane, ukulinganisa ixabiso lombane wokuphuma phakathi kwesiphelo kunye nesiphelo sobonelelo lwamandla olubi.
Ngeentsimbi zentsimbi yesandla, ngokulandelelana, ukucofa isiphelo segalelo ezibini zeamplifier yokusebenza (
Joyina umqondiso wokuxinana)
, kwaye ujonge imeko ye-clock oscillation, eqhelekileyo, i-multimeter pointer iya kuba ne-oscillation enkulu, njenge-pointer ayihambi, ngoko i-amplifier yokusebenza yonakalisiwe.
4.
Ibhayisekile yombane yovavanyo oludibeneyo lwendawo yesekethe.
kumatshini wokupakisha, isiseko sexesha eliqhelekileyo le-555 yesekethe edibeneyo ye-TL494 yesekethe kunye nesekethe.
Makhe sijonge ngokuthe ngqo kumanqaku aphambili eendlela ezithile zovavanyo (
1)
Ukumiselwa kwesekethe edibeneyo ye-T494
umatshini wokupakisha uvavanyo oludityanisiweyo lwesekethe ukumiselwa kwesekethe edibeneyo ye-T494 ngamanyathelo alandelayo.
1)
Lungiselela isixhobo.
Uvavanyo lweesekethe ezidibeneyo ukukhetha imisebenzi emininzi, efana ne-digital multimeter, imodeli ene-MY68 uhlobo olusebenzayo kunye nohlobo lwe-MS820 ye-digital multimeter.
bayakwazi ukubona ukuphindaphinda kwe-150 KHZ kunye ne-200 KHZ.
Kwakhona kufuneka i-oscilloscope, i-adjustable resistance wire winding, njl.
2)
Umlinganiselo we-oscillation frequency.
I-screw multimeter yokuqala ukuya kwi-200 KHZ, uphando lokuqala lwe-T494 izinga lokujikeleza (
Kwenye isekethe edibeneyo enje ngezantsi kwe200hz, inokulungelelanisa igiya)
, ukuze ngokuchanekileyo.
I-T494 oscillation ku-5, kunye neenyawo ezi-6, ngoko ke iipeni ze-multimeter kwaye kwezi nyawo zimbini, zinokumisela i-sawtooth wave.
Itshaja kunye nolawulo lwesekethe ye-oscillation frequency ye-20 ~ 80 kh, iziphumo zokuzimisela zinexabiso elithile, i-oscillation yesekethe edibeneyo iyinto eqhelekileyo, ixabiso le-capacitance yokumelana lilungile.
ukuba akukho zibonakaliso ze-oscillation, iya kukhangela indawo yoqhagamshelwano kunye neepeni kunye, i-wiring, njl.
Ukuba ukuvavanya kwakhona kusengaphantsi komlinganiselo wamanani wesekethe edibeneyo inengxaki.
ukuba i-frequency ayivumelekanga, ukuxelela i-Rr okanye i-Cr, uhlengahlengiso olufanelekileyo lwemeko okanye ukutshintshwa.
3)
Ukulinganisa umlinganiselo womsebenzi.
Ukulungele oscilloscope, uya T494 output pin 9, 10, qhagamshela igalelo interface oscillograph, kwaye phambili ukuya 9, 10 iinyawo kunye nomthwalo rated.
Apha kubalulekile ukuba uqaphele ukuba akukho mthwalo olinganisiweyo, umlinganiselo womsebenzi awukho umlinganiselo ochanekileyo, uphambuke kwixabiso loyilo lwangaphambili.
Qwalasela oscilloscope 9, 10 iinyawo imveliso waveform, kwangaxeshanye lungisa umlinganiselo umsebenzi: ukulawula element, uhlengahlengiso isantya elawula isibambo, ngu 0 spin;
Itshaja, lungisa ixabiso lokuchasa ukusuka kwi-0 ukuya kwi-6 iinyawo (
Umthamo C, ngaxeshanye lungisa)
.
Ngeli xesha ukusuka kwi-oscilloscope kufuneka ubone utshintsho lwe-duty ratio ukusuka kwi-zero ukuya kwikhulu lepesenti.
umatshini wokupakisha isekethe edibeneyo iqhelekile okanye ayinxulumene nomatshini unokusebenza ngokuqhelekileyo, ngoko ke kubalulekile, ndiyathemba ukuba eli nqaku lokupakisha umatshini wokupakisha uvavanyo lwesekethe oludibeneyo luluncedo kuwe.
Nanini na xa umbuzo womatshini wokuweyisha uphakanyiswa, omnye udibana negama elithi ''.
