Lub twj tso kua mis yog ib qho DC rau DC hloov pauv uas siv lub tshuab hluav taws xob rau lub zog khaws cia kom nce lossis qis dua.
Cov twj tso kua mis raug siv rau lub qhov rooj-tsav tsheb siab n-channel zog MOSFETs thiab IGBTs. Thaum qhov nruab nrab ntawm ib nrab tus choj mus qis, lub tshuab hluav taws xob tau them los ntawm lub diode, thiab tus nqi no yog siv tom qab tsav lub rooj vag ntawm FET-sab siab ob peb volts saum toj ntawm qhov hluav taws xob thiaj li hloov nws.
Lub tswv yim no ua haujlwm tau zoo, thiab zam kev nyuaj uas yuav tsum tau khiav lub zog sib cais thiab tso cai kom muaj txiaj ntsig zoo n-channel cov cuab yeej siv rau ob qho tib si.
Lub voj voog no (xav tau kev hloov pauv ib ntus ntawm FET sab siab) kuj tseem yuav raug hu ua "bootstrap" Circuit.

Kab lus no tau txhawb nqa los ntawm JLCPCB.com
LCPCB kuj yog tus txhawb nqa txoj haujlwm no. JLCPCB (Shenzhen JLC Electronics Co., Ltd.), yog lub tuam txhab PCB loj tshaj plaws hauv Suav teb thiab cov chaw tsim khoom lag luam tshwj xeeb tshwj xeeb hauv PCB sai sai thiab tsim cov PCB me me. Koj tuaj yeem xaj yam tsawg kawg ntawm 5 PCBs rau tsuas yog $ 2. Txhawm rau kom tau txais PCB tsim, xa cov ntaub ntawv gerber koj rub tawm hauv cov kauj ruam kawg. Rub tawm cov ntawv.zip lossis koj tseem tuaj yeem rub thiab poob cov ntaub ntawv gerber. Tom qab xa cov ntawv zip, koj yuav pom cov lus ua tiav hauv qab yog tias cov ntawv tau ua tiav tiav. Koj tuaj yeem tshuaj xyuas PCB hauv Gerber tus saib kom paub tseeb tias txhua yam zoo. Koj tuaj yeem saib ob sab saum toj thiab hauv qab ntawm PCB. Tom qab ua kom ntseeg tau tias PCB zoo, tam sim no koj tuaj yeem tso qhov kev txiav txim ntawm tus nqi tsim nyog. Koj tuaj yeem xaj 5 PCBs rau tsuas yog $ 2 ntxiv rau kev xa khoom. Txhawm rau txiav txim, nyem rau ntawm "SAVE TO CART" khawm.
Khoom siv
4.7uF capacitor 25V (electrolytic) - 2 rau txhua lub voj voog
1N4007 diode - 3 rau txhua lub voj voog
47uF capacitor 50V (electrolytic) - 1 rau qhov pov tseg zaum kawg ntawm qhov hluav taws xob
Arduino nano/uno/mini
jumper cov xov hlau
daim ntawv qhia zaub mov
hwj chim qhov chaw (min 5V)
Kauj ruam 1: Schematic
Nws yooj yim heev thiab tsuas yog xav tau ob peb yam.
thov ua raws li schematic muab.
Kauj Ruam 2: Txoj Cai Ua Haujlwm
Hauv ob theem kev hloov pauv, hauv thawj theem ib lub capacitor txuas nrog hla cov khoom, them nws rau tib qhov hluav taws xob. Hauv theem ob qhov kev hloov pauv tau hloov pauv kom lub capacitor nyob rau hauv cov khoom siv thiab thauj khoom. Qhov no ua ob npaug ntawm qhov hluav taws xob hla lub nra - qhov sib npaug ntawm thawj qhov khoom siv thiab lub zog hluav taws xob.
Qhov xwm txheej ntawm qhov hloov pauv hluav taws xob ntau dua yog feem ntau smoothed los ntawm kev siv lub tshuab hluav taws xob tso tawm. Ib qho sab nraud lossis theem thib ob tsav kev hloov pauv, feem ntau ntawm kaum tawm kilohertz mus txog ob peb megahertz. Qhov siab ntau yuav txo qhov peev txheej xav tau, vim tias yuav tsum tau them tsawg dua yuav tsum tau khaws thiab pov tseg hauv lub voj voog luv.
Kauj Ruam 3: Arduino Code thiab PinOut
D12 - teeb liab/theem 1
D13 - teeb liab/theem 2
Vin - ib txwm siv hluav taws xob kom them lub twj tso kua mis thiab arduino (txog 12V)
GND - ib txwm rau qhov kawg capacitor thiab arduino.
Muaj txuas cov screenshot nrog rau.ino cov ntaub ntawv.
qhov ncua sijhawm tuaj yeem hloov kho kom tau txais qhov xav tau txhawb zog.
Kauj Ruam 4: Ua Haujlwm Demo
Thov mus saib kuv tus youtube channel kom tau txais txoj hauv kev ua haujlwm txoj cai thiab ua qauv qhia txog kev them nqi hluav taws xob.
