Kodi chotani?

Olowetsa ndi DC ku THC Osinthirani AC, yomwe ndi njira yosinthira yamagetsi ndi otembenuza. Wotembenuza amatembenuza mphamvu yamafuta a mphamvu ya 12V DC, pomwe wolowetsa amatembenuza voliyumu ya 12V DC ndi mankhwala osokoneza bongo a m'manja; Magawo onsewa amagwiritsanso ntchito nthawi yomwe imagwiritsidwa ntchito posinthira kusinthasintha kwaukadaulo wa ma pulouni (pwm). Gawo la core ndi wolamulira wophatikizira wa pwm wophatikizira, wotsutsa amagwiritsa ntchito UC3842, ndipo wolowetsa amagwiritsa ntchito chip. Mitundu yamagetsi yamagetsi ya Tl5001 ndi 3.6 ~ 40V, ndipo ili ndi vuto lothandizira, chiwongola dzanja cha pwm, kuteteza kwa magetsi komanso madera otetezera.

Gawo lolowera: Gawo lolowera lili ndi zizindikiritso zitatu, 12V DC Ikani Vin, kugwirira ntchito ma volt enb enb ndi Pantl Informal Stud. Vin imaperekedwa ndi adapter, ndi mphamvu ya enb ya enb imaperekedwa ndi a MCU pa bolodi, ndipo mtengo wake ndi 0 kapena 3V. Pamene enb = 0, wolowetsa sagwira ntchito, ndipo a Enb = 3V, wolowetsa ali munthawi yogwira ntchito; Ndipo volyo ya voliyumu imaperekedwa ndi bolodi, ndipo mitundu yake yamitundu ili pakati pa 0 ndi 5V. Miyezo yosiyanasiyana imapangidwanso kumapeto kwa wowongolera pwm, ndipo zomwe wolowetsa ku katunduyo adzakhala osiyananso. Zocheperako zamtengo wapatali, zotulukapo zotulukapo ndi mutu.

Magetsi ayambe kuzungulira: pomwe enb ndi yayitali, magetsi apamwamba kwambiri amatulutsa kuti ayatse chubu chakumbuyo kwa gululi.

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 kusinthira kwa Mos Mosa ndi mphamvu yosungira mphamvu. Kulowetsa kumayikidwa ndi kukonzedwa ndi kukoka kwa okankha ndikuyendetsa molde kuti musinthe, kotero kuti magetsi a DC ndikuchotsa ikuluyi.

LC iscillation ndi Gawo lozungulira: Onetsetsani kuti 1600V Vosyumu ya 1600V inafunika kuti nyali iyambire, ndikuchepetsa mphamvuyo mpaka 800V pambuyo pa 800V pambuyo pa 800V litatha.

Mayankho otulutsa mphamvu: pomwe katunduyo akamagwira ntchito, magetsi amphamvu amathandizidwanso kuti athetse magetsi okwanira.

Kugwira nchito
Olowetsa amatembenuzira mphamvu ya DC Mu mawu a Sing'ana Imakhala ndi mlatho wa osintha, kuwongolera mfundo zoimira.
Mwachidule, wolowetsa ndi chipangizo chamagetsi chomwe chimasintha magetsi otsika (12 kapena 24 volts kapena 48 volts) mphamvu ya DC mu 220 volts mphamvu. Chifukwa mphamvu 220 volts volts nthawi zambiri imakonzedwa mu mphamvu ya DC kuti igwiritsidwe ntchito, ndipo gawo la wolowetsayo ndilombali, chifukwa chake dzinali. M'nthawi ya "kusuntha", ofesi yam'manja, kulumikizana kwa mafoni, kupeza zosangalatsa zam'mayendedwe ndi zosangalatsa. Mukamayenda, osati chabe wamba wamba pamafunika mabatire kapena mabatire osungira, komanso 220-volt amalinganiza pano, zomwe ndizofunikira kwambiri m'moyo watsiku ndi tsiku. Omvera amatha kukwaniritsa zosowa izi.
