Kodi chotani?
Olowetsa amatembenuza DC Mphamvu (batire, batire yosungira) mu mphamvu ya AC (nthawi zambiri 220V, 50hz Sney). Imakhala ndi mlatho wa itteri, kuwongolera mfundo zomveka komanso zosefera.
Mwachidule, wolowetsa ndi chipangizo chamagetsi chomwe chimasintha magetsi otsika (12 kapena 24 volts kapena 48 volts) molunjika bwino mu 220 volts kusintha kwapano. Chifukwa nthawi zambiri timagwiritsa ntchito ma volt 220-volt alinganiza pano kuti atembenukire panopo, ndipo wolowetsa amachita mbali inayo, motero dzinalo.
Omvera amatha kutchulidwa malinga ndi zotulutsa zawo, a. adagawika m'magulu amphepete, b. zosinthika zosinthidwa ndi c. mitsempha yamageni.
Chifukwa chake, tanthauzo la mzungu Wamphamvu ndi wotchinga yomwe zotsatira zake ndi mafunde a sine.
Ubwino wake ndikuti zomwe zidatulutsa ndi zabwino, zosokoneza zimakhala zochepa, ndipo zotulukapo zake zimagwirizana ndi ma acis a Grid. M'malo mwake, mtundu wa Mphamvu ya AC yoperekedwa ndi zabwinoMune Waur inverterndizokwera kuposa za gululi. Wolowetsa wa sinel Serverlent alibe kusokonekera pang'ono kwa wailesi, zida zolankhulirana ndi zida zolumikizirana, phokoso lotsika, katundu wosinthika, ndipo makina onsewa ali ndi mphamvu zambiri; Choyipa chake ndikuti mzerewo ndi mzere wolonjezedwa umakhala wovuta, umakhala ndi zofunikira kwambiri pakuwongolera tchipisi ndi kuteteza, ndipo ndizokwera mtengo.
Zimagwira bwanji?
Musanayambe mfundo yogwira ntchito yaMune Waur inverter, ingoyambitsani mfundo yogwira ntchito.
Olowetsa ndi DC ku TC IC yosinthira ma AC, yomwe ndi njira yamagetsi yopotoza ndi wotembenuza. Wotembenuza amatembenuza mphamvu yamafuta muyezo wa 12V DC, pomwe wolowetsa amatembenuza zida za magetsi 12V DC ndi stapter kukhala magetsi apamwamba kwambiri; Magawo onsewa amagwiritsanso ntchito kusinthasintha kwa ma punsaraphy kumasinthidwe (pwm). Gawo lake lozungulira ndi wolamulira wa pwm wokhala ndi zophatikizira, wotsutsa amagwiritsa ntchito UC3842, ndipo wolowetsa amagwiritsa ntchito Tl5001 Chip. Mitundu yamagetsi yamagetsi ya Tl5001 ndi 3.6 ~ 40V, ndipo ili ndi wolamulira, wojambula wa Oscillator ndi masinthidwe otsika oyendayenda komanso madera otetezera.
Kulowetsa mawonekedwe ophatikizira: Pali zizindikiro zitatu mu gawo, 12V DC Kuyika Vin, ntchito zimathandizira magetsi a ENB ndi Panel Paurgel Store. Vin imaperekedwa ndi adapter, mphamvu ya enb mphamvu imaperekedwa ndi MCU pa bolodi, mtengo wake ndi 0 kapena 3V, pomwe enb = 3V ili mu boma logwirira ntchito; Ngakhale magetsi operekedwa ndi bolodi lalikulu, mtundu wake wa vatirition uli pakati pa 0 ndi 5V. Miyezo yosiyanasiyana imapangidwanso ku magwiridwe antchito a PWM wowongolera pwm, ndipo zomwe wolowetsa ku katunduyo adzakhala osiyananso. Zocheperako zamtengo wapatali, zocheperako zomwe zidatulutsidwa ndi zomwe zimachitika. Bigger.
Madera a voliyumu: Pamene ENB ili pamlingo wapamwamba, imatulutsa magetsi kwambiri kuti ayatse chubu chakumbuyo kwa tebulo.
Woyang'anira PWM: ili ndi ntchito zotsatirazi: magetsi amkati, magetsi amkati, oscillator ndi pwm, kutetezedwa kopitilira muyeso, kutetezedwa kwakanthawi kochepa.
Kutembenuka kwa DC: Kusintha kwa magetsi kumapangidwa ndi kutseka ku shule ndi mphamvu yosungiramo mphamvu. Kulowetsa kumayikidwa ndi kukonzedwa ndi kukoka kokoka kenako ndikuyendetsa molde kuti musinthe, kotero kuti magetsi a DC ndikuchotsa magetsi a magetsi.
LC iscillation ndi Gawo Losindikiza: Onetsetsani kuti 1600V Vosyumu ya 1600V inafunika kuti nyali iyambire, ndikuchepetsa mphamvuyo mpaka 800V Lale la 800V litayamba.
Mayankho otulutsa mphamvu: pomwe katunduyo akamagwira ntchito, magetsi amphamvu amathandizidwanso kuti athetse magetsi okwanira.
(Chithunzi cha sine swew
Kusiyana pakati pa mtsinje wa sine unyinji ndi momwe msewu wamba umakhalira ndi mafunde azungu ndi zida zowonongeka zowonongeka, kotero palibe kusokonezedwa ndi wailesi ndi zida zolumikizirana, ntchito yoteteza ikwanira , ndipo mphamvu zonse ndizokwera.
Chifukwa chomwe aMune Waur inverterimatha kutulutsa funde lonse ndi chifukwa limagwiritsa ntchito ukadaulo wa spwm womwe umaposa ukadaulo wa PWM.
Mfundo ya spwm imakhazikitsidwa pamfundo yofananayo yomwe imagwira ntchito pazinthu zamagulu: Ngati ma pullery achitapo kanthu pazinthu za Peak ndipo nthawi yochita izi ndi yofanana.
Spwm imafanizira mafunde ang'onoang'ono ndi mtengo wokhazikika ndi mtengo wokhazikika (monga kusinthana pafupipafupi 10k) The Services Quine funde pa chipangizocho. Kutalikirana ndi pafupipafupi kwa sine funde zimasinthidwa kuti zipange mafunde a DC Veloge Plash Plasturetion ofanana ndi madera osiyanasiyana ndi ma frequenc.
