• Ayyukan mota: Ƙarfafa kayan lantarki masu muhimmanci a cikin mota ta hanyar rage wutar batir 12V zuwa tsayayyen 5V ko 9V.

Bayanin Hardware

XL4016E1 module ƙarami ne kuma ingantaccen mai daidaita wutar lantarki. Tushen module shine XL4016E1 IC daga XL Semiconductor, mai rage wutar lantarki mai inganci. Module yana da babban inductor don adana makamashi, capacitors na shigarwa da fitarwa don tacewa, da kuma Schottky diode don gyara. Ya kuma haɗa da potentiometer don daidaita wutar fitarwa da kuma maɓallin kunnawa/kashewa don fitarwa, wanda ke da amfani don gwaji da sarrafa wutar.

Module yana da girman kusan 65.1mm x 42.5mm kuma yana da nauyin gram 48.7. Yana da ramuka huɗu na hawa kuma ana iya saka shi da standoffs, yana sauƙaƙa shigarwa a cikin akwatuna. Terminals na shigarwa da fitarwa an yi musu alama a fili, kuma module ya haɗa da LED mai nuna wutar da ke nuna lokacin da fitarwa ke aiki.

Hardware/Abubuwan Haɗi

Don wannan bita da gwaji, an yi amfani da waɗannan abubuwan:

• XL4016E1 DC-DC Step Down Power Supply Module
• Variable DC power supply (don wutar shigarwa)
• Electronic load (DL3031) don kwaikwayon nau'ikan wutar fitarwa daban-daban
• Digital multimeters (don auna wutar lantarki da wutar)
• Power meter (don auna wutar shigarwa, wutar, da ƙarfi)
• Thermal camera (don lura da yanayin zafin abubuwan)

Jagorar Haɗin Waya

Haɗin waya don wannan module abu ne mai sauƙi. Kamar yadda mai gabatarwa ya bayyana a cikin bidiyon, wutar shigarwa tana haɗuwa da terminals "IN", kuma kayan aiki suna haɗuwa da terminals "OUT". Ana sanya power meter a jere tare da shigarwa don auna wutar shigarwa da wutar, yayin da fitarwa ke haɗuwa da electronic load don kwaikwayon nau'ikan wutar fitarwa daban-daban. Ana daidaita wutar fitarwa na module ta amfani da potentiometer na ciki.

Bayanin Code

Wannan aikin bita ne na hardware, don haka babu code da ake buƙata ko bayarwa. XL4016E1 module abu ne na analog kawai, wanda aka tsara gaba ɗaya ta hanyar potentiometer na ciki. Don saita wutar fitarwa da ake so, kawai ka haɗa wutar shigarwa, ka haɗa kayan aiki, kuma ka juya potentiometer har sai wutar fitarwa ta dace da burinka. Ana ba da shawarar duba fitarwa da multimeter yayin yin gyare-gyare.

Aikin Kai Tsaye/Nunawa

Tsarin gwaji ya ƙunshi jerin gwaje-gwaje masu tsauri don kimanta aikin module a ƙarƙashin yanayin shigarwa da fitarwa daban-daban. Mai gabatarwa ya gwada ikon module na kiyaye tsayayyen wutar fitarwa yayin ɗaukar nau'ikan wutar daban-daban. Manyan gwaje-gwaje sun haɗa da:

• Mafi ƙarancin wutar fitarwa: Tare da shigarwa na 30V, module ya iya daidaita fitarwarsa zuwa mafi ƙarancin 1.268V.
• Mafi girman wutar fitarwa: Tare da shigarwa na 40V, mafi girman tsayayyen fitarwa shine 36V.
• Daidaiton wutar: An gwada module don ganin yadda yake kiyaye saitin wutar fitarwa (misali, 5V, 15V, 3.3V) yayin da ake rage wutar shigarwa. An gano cewa ana buƙatar mafi ƙarancin wutar shigarwa na kusan 5.5V don kiyaye tsayayyen fitarwa na 5V.
• Ƙarfin ɗaukar wutar: An gwada module da nau'ikan wutar daban-daban har zuwa 8A. A yawancin tsare-tsare, ya ɗauki 8A tare da ƙarancin raguwar wutar. Duk da haka, a wasu lokuta, kamar fitarwa na 12V daga shigarwa na 30V, module ya yi wahala wajen kiyaye tsayayye a manyan wutar, yana nuna raguwar wutar mai yawa. Mai gabatarwa ya lura cewa a 5A, module ya yi kyau sosai a mafi yawan yanayi.
• Inganci: An ƙididdige inganci ta hanyar raba ƙarfin fitarwa da ƙarfin shigarwa. Gwaje-gwaje sun nuna inganci na kusan 76% zuwa 81% a tsare-tsare daban-daban, wanda ya dace da mai daidaita wutar lantarki a ƙarƙashin kaya.
• Aikin zafi: An yi amfani da thermal camera don lura da zafin regulator IC da Schottky diode. A lokacin gwaje-gwaje masu nauyi, regulator IC ya kai zafin har zuwa 100°C, wanda ke cikin iyakar zafin aiki amma yana nuna cewa ana iya buƙatar isasshen sanyaya don ci gaba da amfani da ƙarfi mai girma.
