Nigute ushobora gukemura vuba amakosa yimashini ya TX2 MGCU-2?

Uyu munsi, GeekValue izabagezaho ibitekerezo byo kubungabunga MGCU-2 （03117531） kubikoresho bya mashini ya TX2

Iyo imashini ishyira mu bikorwa ikora, MGCU-2 （03117531 often ikunze kwangirika bitewe nubushyuhe budahindagurika nubushuhe budahwitse mumahugurwa cyangwa voltage idahinduka mumahugurwa. Kubwibyo, gukoresha ingufu nubushyuhe nubushuhe bwa SMT bigomba kugenzurwa kenshi kugirango bikureho amakosa amwe. Yataye, uyumunsi nzabagezaho uburyo bwo gukemura nibitekerezo byo kubungabunga mugihe MGCU-2 （03117531） ibice byimashini ya TX ikurikirana idasanzwe.

MGCU2 igizwe nimbaho ​​ebyiri: ikibaho cyo kugenzura nubuyobozi bwimbaraga

1. Uburyo bwo gukemura ibibazo byubuyobozi bwimbaraga nuburyo bukurikira:

Kugenzura amashanyarazi nyamukuru ya x2.p, banza upime niba DC 300V ari mugufi-kuzunguruka hasi - ni ukuvuga, kugirango umenye niba ubushobozi butatu bwa voltage igenzura filter yamenetse. Ibyiza 300v ya capacitor nini ninjiza yumuzingi wa inverter. Inverter umuzenguruko ugizwe na 6 IGBTs (imbaraga nyinshi za mos tubes). Diode ihujwe kuburinganire hagati ya CE pole ya buri IGBT. Buri G pole igenzurwa na moderi ya kabiri ya calculus modulator hamwe numushoferi ugezweho, kandi buri IGBTs ihujwe na CE isohora icyiciro cya voltage (U, V, W); 6 IGBTs igomba gukurwaho mugihe ugenzura inzitizi za inverter Gupima niba ari nziza cyangwa mbi, kandi buri chip yo kugenzura irashobora kandi kumenya niba ari ibisanzwe hakoreshejwe uburyo bwo gupima static.

2. Ibitekerezo byo gukemura ibibazo byubuyobozi bugenzura nibi bikurikira:

1) Gupima niba insimburangingo ya canbus (4 yose hamwe) ikora neza, ni ukuvuga, niba buri pin pin ya logique ari mugufi.

2) Gupima niba hari umuzunguruko mugufi muri microprocessor (BGA). Mubisanzwe, capacator nyinshi zahujwe inyuma ya BGA. Koresha buzzer ya multimeter kugirango umenye niba hari uruziga rugufi. Niba hari umuzunguruko mugufi, bivuze ko BGA yangiritse. Gusenya umwuga.

3) Mubyongeyeho, hari umubare munini wa bisi yohereza amakuru ya chip / op amps / igereranya ku kibaho. Hamwe nubufasha bwa IC datasheet, birashoboka gukemura umwe umwe, bifata igihe kirekire.

4) 24v kugeza 3.3v / 5v chip yo gutanga amashanyarazi nayo iri kubibaho. Amashanyarazi ya chip nyamukuru agenzura ni 2.5V, kubwibyo hariho bibiri 5v kugeza kuri 2.5v buck yamanutse hasi hamwe na chipi ya voltage igenzura kugirango ihure na IC igenzura rikomeye. Amashanyarazi arahagaze.

Nyuma yuko ingingo zose zavuzwe haruguru zimaze kugaragara kandi kubungabunga ni byiza, igihe kirageze cyo kugerageza kuri mashini. Iki nigitekerezo cyo kubungabunga Xlin-smt kumusozi wa TX2 MGCU-2 （03117531）. Niba ufite ibitekerezo bitandukanye, ikaze kungurana ibitekerezo! Xlin-smt nisosiyete izobereye mugutanga igisubizo kimwe kumashini zishyirwa. Yagize uruhare runini mu nganda zimashini zimara imyaka 15, zitanga kugurisha imashini zishyira, gukodesha, gutanga ibikoresho byabigenewe, gufata neza ibikoresho, gufata neza ibinyabiziga, kuguruka Kugeza kubungabunga, gufata neza umutwe, amahugurwa ya tekinike yubucuruzi bwuzuye!
