Nyob zoo phooj ywg, Hnub no kuv tab tom yuav ua ib qho kev tswj hwm qhov hluav taws xob. Yog siv lub voj voog no peb tuaj yeem hloov mus txog 35V DC mus rau 9V DC.
Cia peb pib,
Kauj Ruam 1: Nqa Txhua Cheeb Tsam Raws Li Qhia Hauv Qab
Cheebtsam yuav tsum tau -
(1.) Tus tswj hluav taws xob - 7809 x1
(2.) Capacitor - 63V 470uf x1 {Ntawm no kuv siv 25V 470uf capacitor vim tias kuv yuav muab 17V DC Input.}
(3.) Capacitor - 16/V25V/63V 100uf x1
(4.) Lub Hwj Huam Lub Hwj Huam Siv Hluav Taws Xob hauv DC - Cov tswv yim hluav taws xob <35V {Cov khoom siv hluav taws xob yuav tsum tsawg dua 35V DC}
(5.) Txuas xov hlau
(6.) Clippers
Kauj Ruam 2: 7809 Voltage Regulator Pins
Daim duab no qhia cov pins ntawm tus tswj qhov hluav taws xob no.
Pin-1 yog Cov Tswv Yim, Pin-2 yog GND (Hauv av) thiab
Pin-3 yog Cov Zis.
Kauj Ruam 3: Txuas 470uf Capacitor
Solder +ve pin ntawm 470uf electrolytic capacitor rau Input pin/Pin-1 ntawm qhov ntsuas hluav taws xob thiab
Solder -ve tus pin ntawm lub capacitor rau GND Pin ntawm Tus Tswj Hluav Taws Xob raws li koj tuaj yeem pom hauv daim duab.
NCO TSEG: Qhov hluav taws xob ntawm lub capacitor yuav tsum ntau dua li cov tswv yim hluav taws xob. Yog li txuas 63V 470uf capacitor mus rau qhov sib txuas ntawm lub zog hluav taws xob raws li kuv txuas rau hauv daim duab, tab sis ntawm no kuv tuaj yeem siv 25V 470uf capacitor vim tias kuv yuav tsum muab 17V Cov tswv yim uas tsawg dua Capacitor qhov hluav taws xob
Kauj Ruam 4: Txuas 100uf Capacitor
Tom ntej solder +ve pin ntawm 100uf electrolytic capacitor rau Output tus pin ntawm tus tswj hluav taws xob thiab
Solder -ve tus pin ntawm lub capacitor rau GND Pin ntawm qhov ntsuas hluav taws xob zoo li koj tuaj yeem pom hauv daim duab.
Kauj Ruam 5: Txuas Clipper Hlau rau 9V Cov Khoom Siv Hluav Taws Xob
Tam sim no peb yuav tsum txuas cov xov hlau txuas kom tau txais qhov 9V DC Output los ntawm qhov Circuit no.
Solder +ve cov xaim tso tawm rau tus lej pin ntawm qhov ntsuas hluav taws xob thiab
Cov kab laug sab -v tso zis hlau rau GND Pin ntawm Tus Tswj Hluav Taws Xob raws li cov kab laug sab hauv daim duab.
Kauj Ruam 6: Txuas Cov Khoom Siv Hluav Taws Xob
Tam sim no peb cov phiaj xwm tau npaj tiav yog li txuas Cov Khoom Siv Hluav Taws Xob rau lub xov tooj cua no.
Txuas +ve clip ntawm Cov tswv yim hluav taws xob rau +ve tus pin ntawm 470uf capacitor thiab
-ve clip rau GND Pin ntawm tus tswj hluav taws xob.
NCO TSEG: Peb tuaj yeem muab Cov Khoom Siv Hluav Taws Xob tso tawm qhov siab txog 35V DC rau hauv Circuit no.
Kauj Ruam 7: Nyeem Ntawv
Tam sim no raws li koj tuaj yeem pom hauv cov duab saum toj no.
Daim duab-1)-Kuv Muab 17.6V DC Input thiab peb tau txais 9V qhov tso tawm tas li los ntawm Circuit no raws li koj pom hauv daim duab -2.
NCO TSEG 1: Yog tias peb yuav nce qhov hluav taws xob tawm tam sim no qhov hluav taws xob tso tawm yuav zoo ib yam li piv txwv li 9V DC.
Zoo li qhov no peb tuaj yeem ua ib qho kev sib txuas kom tau txais qhov hluav taws xob 9V tas mus li siv 7809 Tus tswj hluav taws xob.
NCO TSEG 2: Ntxiv lub rhaub dej kub yog tias 7809 Cov ntsuas hluav taws xob tau txais cua sov.
