Yog tias koj xav ntsuas qhov inductance, lub peev xwm ntawm ib qho kev tivthaiv ces koj xav tau cov nthwv nthe nthwv dej nthwv dej hauv kab lus no peb kawm txog qhov no.
Kauj ruam 1: Yees duab
Yog xav paub ntxiv koj tuaj yeem tshawb xyuas kuv cov vis dis aus.
Kauj ruam 2: Paub meej
Yog tias peb xav ntsuas Inductance, Resonance zaus, Capacitance ntawm lub capacitor, peb xav tau nrawm nrawm square nthwv dej los ntawm txhua lub tshuab hluav taws xob zoo tab sis yuav ua li cas yog tias peb tsis muaj lub tshuab tsim hluav taws xob kim, peb tuaj yeem ua lub tshuab hluav taws xob sib txawv tab sis nws tsis muaj cov npoo nrawm, yog li peb yuav ua kom nrawm nrawm ntug nthwv dej.
Dab tsi yog ntug nrawm txhais tau tias- Raws li peb paub yog tias peb tab tom tsim cov xwm txheej yoj los ntawm ib qho khoom siv Rising thiab poob ntawm qhov hluav taws xob tsim cov xwm txheej nthwv dej piv txwv li qhov nce thiab ntog ntug yuav tsum nrawm kuv txhais tau tias nrawm heev los ntsuas lub peev xwm, inductance raws li peb tuaj yeem pom hauv daim duab.
Ua hauj lwm-
7414N yog qhov tseem ceeb ntawm txoj haujlwm no nws yog HEX SCHMITT-TRIGGER INVERTER. nws thawj cov channel tau siv los ua oscillator nrog kev pab ntawm 100nf thiab 6k capacitor thiab resistor ces so ntawm 5 channel tau siv ua ke kom txo qis kev tawm tsam.
koj tuaj yeem hloov c1 thiab r1 rau qib sib txawv raws li koj xav tau, kuv tau sim nws nws ua haujlwm zoo.
Kauj Ruam 3: Rising Ntug Hla Tua (Ntiv Nplhaib)
Hla Tua nyob ib puag ncig 2-3% hauv kuv qhov xwm txheej, Siv Lim Capacitor los lim thiab ua kom du dc ntawm qhov tso tawm, tsis txhob siv Polarity tiv thaiv diode nws ua rau overhoot ntau dua. hauv kuv qhov xwm txheej nws yog qhov zoo yog tias koj xav kom ntub dej ntau dua kom raug thiab ua raws cov theem hauv qab no.
Ntxiv lub zog loj rau ntawm lub khob cij hla cov khoom xa khoom, ze rau IC Pib nrog 100 uF. ua rau txhua 3 lub tshuab hluav taws xob saum toj no mus rau qhov tsawg kawg nkaus uas tseem yuav ua rau muaj kev sib cuag zoo nrog cov neeg sib tham hauv lub khob cij. Cov coj ua no ntxiv qhov inductance koj tsis xav tau. Ntau ntxiv los ntawm cov zis koj tau nyeem rau tus pin hauv av, ze rau ntawm tus pin tso tawm kom ntau li ntau tau - 220 Ohms yuav tsum zoo, thiab ntxiv koj xav tau coj mus txiav kom tsawg. koj yuav tsum tsis txhob hla dhau / tshem tawm dhau ob peb puas milliVolts, ntxiv cov teeb liab me me Schottky diodes los ntawm tus pin tso rau ob qho khoom siv thiab hauv av pins raws li qhia hauv Duab.
Qhov no yuav ua kom ntseeg tau tias lub ncov ntawm qhov nce ntawm ntug thiab nqaum ntawm ntug ntog ntawm lub suab nrov tau damped - yuav muaj qee qhov cuam tshuam rau ntawm lub trough / ncov ntawm lub suab nrov ib yam vim tias lub zog ntau dhau ntawm qhov peaks tau ploj mus thoob plaws Thaum kawg, daim ntawv qhia zaub mov, vim yog qhov xwm txheej ntawm nws txoj kev tsim kho, qhia txog kev muaj peev xwm, kev siv hluav taws xob, thiab txhua yam kev sib kis kab mob. Txawm tias yooj yim perf-board yuav ua tau zoo dua. Ntev ua rau qhov teeb meem no hnyav dua, tshwj xeeb tshaj yog nyob hauv qhov ntau zaus / hloov pauv ntse, qhov twg txawm tias cov hlau xaim yooj yim yog lub hauv paus ntawm kev sib txuas thiab lub suab nrov.
Kauj ruam 4: Txhua yam ua tiav
Thov tawm lus yog tias koj muaj teeb meem
