2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Nyob zoo, muaj cov phooj ywg niaj hnub no peb yuav ua lub inverter hauv tsev nrog Mosfet transistor thiab tshwj xeeb oscillator board.

Lub zog hloov hluav taws xob, lossis hloov pauv, yog lub tshuab hluav taws xob lossis cov khoom siv hluav taws xob uas hloov pauv ncaj qha tam sim no (DC) mus rau qhov hloov pauv tam sim no (AC).

Kauj Ruam 1: 12v txog 220v Inverter

Ib qho cuab yeej siv hluav taws xob hloov pauv lossis hloov pauv yuav tsum muaj lub zog DC ruaj khov uas muaj peev xwm muab tau tam sim no txaus rau lub zog xav tau ntawm lub system. Qhov ntsuas hluav taws xob nyob ntawm qhov tsim thiab lub hom phiaj ntawm inverter. Piv txwv xws li:

12 V DC, rau cov neeg siv khoom me me thiab hloov pauv kev lag luam uas ib txwm ua los ntawm kev rov ua dua 12 V lead acid roj teeb lossis hluav taws xob tsheb hluav taws xob. 24, 36 thiab 48 V DC, uas yog cov qauv rau kev siv hluav taws xob hauv tsev. 200 txog 400 V DC, thaum lub zog yog los ntawm cov khoom siv hnub ci photovoltaic. 300 txog 450 V DC, thaum lub zog yog los ntawm hluav taws xob tsheb roj teeb ntim hauv tsheb-rau-kab sib chaws..

Kauj Ruam 2: Homemade Inverter Nrog Mosfet

Qhov txiaj ntsig tseem ceeb ntawm MOSFET yog qhov nws xav tau yuav luag tsis muaj cov tswv yim tam sim no los tswj lub thauj khoom tam sim no, thaum piv nrog bipolar transistors. Hauv "kev txhim kho hom" MOSFET, qhov ntsuas hluav taws xob tau siv rau lub qhov rooj davhlau ya nyob twg nce kev ua haujlwm ntawm lub cuab yeej. Hauv "hom depletion" transistors, qhov hluav taws xob tau thov ntawm lub qhov rooj txo qhov kev coj ua.

Kauj Ruam 3: Inverter Oscillator

Kev siv hluav taws xob oscillator yog hluav taws xob hluav taws xob uas tsim tawm ib ntus, oscillating cov teeb liab hluav taws xob, feem ntau yog sine wave lossis ib puag ncig yoj. Oscillators hloov ncaj qha tam sim no (DC) los ntawm lub zog xa mus rau qhov hloov pauv tam sim no (AC) teeb liab. Lawv tau siv dav hauv ntau yam khoom siv hluav taws xob.

Nrog qhov tau hais tias cia peb npaj mus sib sau ua lub tsev inverter.

Kauj Ruam 4: Ua Ib Qhov Inverter Yuav Tsum Tau

Txhawm rau ua kom lub tsev inverter 12v txog 220v peb yuav xav tau cov hauv qab no:

Lub oscillator board

Mosfet transistor: IRFZ44N

Lub tshuab hluav taws xob tsis muaj lub kais nruab nrab (los ntawm lub xov tooj cua qub, lub tsheb them nyiaj)

Thiab dc fais fab mov (roj teeb, roj teeb pob los ntawm 18650, tsheb pib roj teeb)

Kauj Ruam 5: Ntau Ntxiv Txog Pawg Neeg Saib Xyuas no

Qhov no yog qhov tseem ceeb tshaj plaws ntawm qhov hloov pauv, hauv qhov hloov pauv kom raug, qhov no tau hloov nrog lub suab yoj oscillator. Qhov no nws muaj 3 tus pin: VCC. GND. Out Raws li koj pom hauv daim duab saum toj no peb yuav tsum muab lub zog cais rau lub rooj tsavxwm no, thiab kuv tsuas xav tau 4v kom nws ua haujlwm. Yog li + lub davhlau ya nyob twg los ntawm lub roj teeb mus rau vccand lub - davhlau ya nyob twg rau GND, thiab cov zis tawm yuav yog + thiab ib qho av (-). Tam sim no tawm (+) davhlau ya nyob twg peb yuav txuas mus rau G lub davhlau ya nyob twg ntawm mosfet (ib qho ntawm sab laug) thiab GND mus rau sab xis davhlau ya nyob twg ntawm mosfet (S).

Kauj Ruam 6: Transformer

Lub tshuab hloov hluav taws xob yog lub tshuab hluav taws xob uas hloov hluav taws xob hluav taws xob ntawm ob lossis ntau lub voj voog los ntawm kev siv hluav taws xob sib nqus. Qhov sib txawv tam sim no hauv ib lub kauj ntawm tus hloov pauv ua rau muaj qhov sib nqus sib nqus, uas ua rau induces qhov hluav taws xob hauv ob lub kauj. Lub zog tuaj yeem hloov pauv ntawm ob lub coils los ntawm kev sib nqus, tsis muaj cov hlau txuas ntawm ob txoj kab hluav taws xob. Faraday txoj cai lij choj ntawm kev tshawb pom pom xyoo 1831 tau piav qhia qhov txiaj ntsig no.

Hauv peb qhov xwm txheej, peb yuav siv lub tshuab hloov pauv rov qab, txhais tau tias peb yuav muab lub zog rau nws cov zis ib txwm muaj thiab peb yuav tau txais qhov hluav taws xob 220v (lossis kaw) rau nws cov kab hluav taws xob ib txwm siv, tsuas yog saib rau cov xov hlau tuab uas yuav yog qhov tso tawm ib txwm muaj (hauv qhov xwm txheej no peb cov tswv yim). Peb yuav txuas cov tswv yim txuas nruab nrab ntawm + ntawm lub zog hluav taws xob thiab D (tus pin nruab nrab ntawm mosfet)

Kauj Ruam 7: Peb Muaj Teeb Los Ntawm Cov Roj Teeb

Tam sim no yog tias txhua qhov kev sib txuas tau ua thiab raws nraim rau qhov kev piav qhia peb yuav tsum hnov suab nrov nrov thiab qhov ntawd yog

ib qho cim qhia tias peb mosfet tab tom ua haujlwm beeing hloov los ntawm pawg thawj coj oscillator thiab tab tom nce qhov hluav taws xob los ntawm 12v txog 220v nrog kev pab ntawm kev hloov pauv.
