Dab tsi yog inverter?

Lub inverter yog DC rau AC transformer, uas yog qhov tseeb yog qhov kev hloov hluav taws xob nrog lub converter. Lub Converter hloov cov pob hluav taws xob ntawm lub hwj huam ntawm lub pob zeb ruaj khov rau hauv ib qho kev hloov pauv ntawm 12v kev hloov pauv ntawm lub 12v kev hloov pauv mus rau hauv cov khoom hluav taws xob siab-voltage ac; Ob qho tib si feem tseem siv cov pulse dav dav dav dav (PWM) thev naus laus zis. Qhov tseem ceeb tshaj plaws yog PWM kev sib xyaw ua ke (cov Adapter siv UC3842, thiab Inverter siv TL5001 Chip. Cov kev siv hluav taws xob khiav ntawm TL5001 yog 3.6 ~ 40v, thiab nws muaj lub tshuab hluav taws xob, ib qho hluav taws xob tiv thaiv kev tiv thaiv kev tswj hwm, qhov hluav taws xob tsis tshua muaj zog hluav taws xob thiab lub voj voog luv nqi tiv thaiv Circuit.

Cov tswv yim interface: Cov lus qhia tawm muaj 3 lub cim, 12v DC cov lus qhia VIN, ua haujlwm kom voltage enb thiab vaj huam sib luag tam sim no kev tswj teeb liab tsaus. Vin yog muab los ntawm cov adapter, thiab enb voltage yog muab los ntawm MCU ntawm Motherboard, thiab nws tus nqi yog 0 lossis 3V. Thaum enb = 0, lub inverter tsis ua haujlwm, thiab thaum enb = 3V, lub inverter yog nyob rau hauv ib txwm ua haujlwm lub xeev; Thiab Dim voltage yog muab los ntawm motherboard, thiab nws cov kev hloov pauv hloov ntawm 0 thiab 5V. Txawv Dim qhov tseem ceeb yog pub rov qab rau lub tswv yim xaus ntawm lub PWM maub los, thiab cov khoom tam sim no los ntawm lub inverter yuav tseem sib txawv. Tus me dua tus nqi qis dua, qhov ntau dua cov tso zis tam sim no los ntawm Inverter.

Voltage Pib Loop: Thaum enb yog siab, siab voltage yog tsim tawm kom pom lub teeb ci rau lub backlight raj ntawm lub vaj huam sib luag.

PWM maub los: nws muaj cov haujlwm hauv qab no: Cov Kev Tiv Thaiv Sab Hauv, Oscillator Kev Tiv Thaiv, Kev Tiv Thaiv Hauv Underventage, thiab tso tawm cov khoom siv luv luv.

DC hloov dua siab tshiab: ntsuas hluav taws xob hloov dua tshiab yog sib sau ntawm Mos Hloov Tube thiab lub zog cia Inductor. Cov tshuaj nkag rau cov pa tawm los ntawm lub laub-rub tawm thiab ua rau lub siab voltage thiab tshem tawm cov inductor, kom lwm qhov kawg ntawm inductor tuaj yeem txais AC voltage.

LC oscillation thiab tso zis Circuit Court: Nco ntsoov 1600V voltage yuav tsum muaj lub teeb kom pib, thiab txo qhov hluav taws xob mus rau 800v tom qab lub teeb pib.

Cov zis hluav taws xob tawm tswv yim: thaum lub nra ua haujlwm, tus qauv voltage yog pub rov qab cov hluav taws xob tawm ntawm kuv inverter.

Rooj mov
Lub Inverter hloov kho DC Fais (roj teeb, cia roj teeb) rau hauv AC fais fab (feem ntau 220V50hz sine lossis square yoj). Nyob rau hauv Layman cov lus, ib qho inverter yog ib qho cuab yeej uas hloov ncaj qha tam sim no (DC) rau lwm tus tam sim no (AC). Nws muaj cov inverter choj, tswj cov lus log thiab lim.
Tsuas yog muab tso, ib qho khoom siv hluav taws xob yog cov khoom siv hluav taws xob uas cov neeg hloov hluav taws xob (12 lossis 248 Volts lossis 48 Volts) DC Fais rau rau 220 Volts ac Fais Fab. Vim tias 220 volts ac fais fab feem ntau yog rectified rau hauv DC lub zog rau kev siv, thiab lub luag haujlwm ntawm inverter yog qhov rov qab, yog li lub npe. Nyob rau hauv ib lub sijhawm ntawm "mus ncig ua si", mobile kev sib txuas lus, kev lom zem mobile, kev lom zem. Thaum nyob ntawm qhov txav, tsis tsuas yog tsawg-voltage ncaj qha yog xav tau los ntawm cov roj teeb lossis kev cia roj teeb, tab sis kuj yog 220-volt hloov tshiab hauv lub neej txhua hnub. Inverters tuaj yeem ua kom tau raws li cov kev xav tau no.
