Switching fais fab mov rau lawv tus kheej txhais tes: nta ntawm lub rooj sib txoos thiab hloov

Lub ib thooj ntawm cov hluav taws xob yuav tsum nyob rau hauv lub hwj huam mov mus rau lub DC voltage ntawm 12 volts. Switching Hwj chim Khoom siv nrog koj ob txhais tes mus dhau ntawm lub nti nrog yuav tsum tau tsis. Xaiv nws yog nqa rau xov tooj cua engineering ntxhuav. Winding down transformer ua rau ib tug ferrite nplhaib khoom qib - M200MN.

raug transformer

Lub hom winding muaj ib insulated hlau MGTF 0.7 ntawm ob nyob ntawm tej PEV-1 uas tau raug daim ntau quav tso ob zaug. Nruab nrab ntawm lawv yuav tsum ua tau ib tug insulating txheej uas yog ua los ntawm PTFE daim kab xev. Cov theem nrab winding nyob rau hauv nruab nrab ib feem muaj ib tug ntxiv ceg rau lub hwj chim kev tswj nti. nyob ntawm tej sab nraum raug kaw nrog ib tug muab ob npaug rau txheej ntawm Teflon daim kab xev.

Switching fais fab mov rau lawv tus kheej txhais tes yog mounted rau ib tug luam Circuit Court board ua los ntawm fiberglass mog. tej khoom ntau lawm technology yog piav nyob rau hauv kom meej nyob rau hauv cov ntawv qhia thiab tshaj lub Scope ntawm no tsab xov xwm. Xam kev paths rau PCB tsim rau lub hauv paus ntawm qhov siv tswvyim ntawm tus dais. Rau transistors xav tau dab uas yog ua los ntawm ib tug txhuas phaj.

Yuav tsum tau mloog xov tooj cua

Raws li ib tug tswv yim zawm caj pas yog zoo siv uas twb muaj lawm inductors, muab tso rau feem ntau nyob rau hauv xws khoom siv fais fab los yog tus kheej lub computer qhia. Lub capacitor yog xam los ntawm cov capacitance thiab lub hwj chim piv ntawm ib tug rau ib. Lub rectifier yog ua lub hauv paus ntawm lub diode choj nrog ib tug tsawg operating zaus. Xws li ib tug ntaus ntawv yuav muab ib tug tam sim no lub dag lub zog uas tau los 3 amperes mus rau lub tso zis.

Siv nyob rau hauv xov tooj cua switching fais fab mov Circuit Court uas tau ntev ua hauj lwm thiab soj ntsuam, yog transistor keyboards. Xaiv transistors yog ua ntawm lub teeb tsis, ib tug zoo-cov pov thawj series IRF 840, los yog VT 1 thiab VT3. Transistors los muab cov kev tsim nyog kub yuav tsum muaj tshav kub dej kom tshem tawm cov tshav kub surplus.

Switching khoom siv fais fab nrog lawv ob txhais tes mus rau cov qhov tso zis feem ntawm lub Circuit Court yog muab los ntawm lub throttles raws li ferrite lub tog raj kheej txog 40 mm nyob rau hauv ntev nrog ib lub cheeb ntawm 3 hli. Kaw ntom nti Winding yog ua los ntawm cov tib hlau li ob winding ntawm lub transformer. Kev siv ntawm lwm txoj kev rau stabilizing cov qhov tso zis pab pawg neeg, tab sis cov pov thawj cia siab rau ntawm circuits. Nrhiav rau lwm txiav txim siab nyob rau hauv cov ntaub ntawv no yuav tsum muaj ib tug pov tseg ntawm lub sij hawm.

Los ua ke thiab kev hloov

Zoo fais fab mov rau lawv tus kheej txhais tes soldered rau npaj board. Thaum lub installation yog tsim nyog los muab tej teeb pom kev zoo ntawm lub chaw ua hauj lwm thiab cua. Tom qab lub soldering yog pom zoo kom mus saib cov ntseeg ntawm lub installation ntawm hluav taws xob Cheebtsam thiab kev sib cuag nruab nrab ntawm lawv thiab cov conductive paths. Nyob rau lub puab nto ntawm lub ntxuav solder flux residues uas yuav ua rau lub Circuit Court.

Switching Hwj chim Khoom siv, sau nws tus kheej ob txhais tes thiab npaj tso, nws yog pom zoo kom thauj resistor tam sim no txawj thaum lub sij hawm soj ntsuam. Qhov no yuav siv tau raws li ib tug incandescent teeb hwj chim ntawm 60 W, nws momentary hloov bude ib qhov taw qhia ntawm kom los ua ke.
