Bita'in 2A DC-DC Step up boost converter MT3608 module

Bita MT3608 Mai Daɗa Wutar Lantarki (Boost Converter) & Gwajin Aiki Na Gaskiya

A cikin wannan bita, mun duba sosai kan sanannen MT3608 boost converter module kuma mun gwada abin da zai iya yi a yanayin gaske. Wannan ƙaramin allo sau da yawa ana tallata shi a matsayin “2A/3A booster,” amma kamar yadda za ku gani a gwajin nauyi, zafi da raguwar wutar lantarki sune ainihin iyaka—musamman idan kuna ƙoƙarin tura babban wutar lantarki a babban fitarwa. 

Abin Da Wannan Module Yake Yi

Boost converter (step-up converter) yana ƙara ƙaramin wutar lantarki na DC zuwa babban wutar lantarki na DC. A wannan gwajin bidiyo, ana amfani da module don ɗaukar abubuwan shigarwa na yau da kullun kamar 3.3V ko 5V kuma a ɗaga su zuwa fitarwa kamar 9V, 12V, ko ma har zuwa babban kewayon 20V. Ana iya daidaita fitarwar ta amfani da potentiometer mai juyi da yawa da ke kan allo. 

Manyan Sassan Akan Module MT3608

MT3608 Step-Up Converter IC

Zuwan allo shine MT3608 switching regulator. A cikin bidiyon, takardar bayanai ta nuna mahimman fasaloli kamar:

• Babban mitar sauya wuta kusan 1.2MHz (ƙananan abubuwan waje na iya yiwuwa).
• Kewayon shigarwa a cikin da'awar yau da kullun na ~2V zuwa 24V.
• Fitarwa har zuwa kusan 28V (gwajin ya kai kusan 27.7V).
• Da'awar inganci “har zuwa ~97%” (ya dogara sosai akan wutar lantarki da rabon ƙarfin lantarki). 

Inductor (L)

Inductor shine babban ɓangaren adana makamashi wanda ke sa ƙara wutar lantarki ya yiwu. Yayin aiki, mai sauya wuta yana saurin sauya wutar lantarki ta cikin inductor, sannan ya saki wannan makamashi don ɗaga fitarwar.

Potentiometer Mai Juyi Da Yawa

Wannan module yawanci yana amfani da multi-turn trimmer. Wannan yana nufin kuna iya buƙatar juya shi sau da yawa (yawanci 15–20 juyi) kafin ku ga canji a fitarwa. Idan kun juya shi kuma babu abin da ya faru da farko, ci gaba da juyawa—kada ku ɗauka ya lalace.

Wuraren Shigarwa/Fitarwa

Module yana da wurare huɗu/fil:

• VIN+ (shigarwa mai kyau)
• VIN- (ƙasa ta shigarwa)
• VOUT+ (fitarwa mai kyau)
• VOUT- (ƙasa ta fitarwa)

Tabbatar kun haɗa ƙasa daidai—ƙasar shigarwa da fitarwa suna ɗaya a wannan nau'in module.

Haɗin Waya Na Asali Da Aka Yi Amfani Da Shi A Gwaji

Saitin gwajin yana da sauƙi:

• Haɗa wutar lantarki zuwa VIN+ da VIN-.
• Haɗa voltmeter (ko multimeter) zuwa VOUT+ da VOUT-.
• Daidaita potentiometer don saita fitarwar da ake so.
• Don gwajin nauyi, haɗa electronic load zuwa fitarwa.

Bayanan Gaggawa Kafin Ku Yi Amfani Da Shi

• Shigarwa dole ya isa: module ba zai iya daidaita yadda ya kamata ba idan ƙasa da wani matakin shigarwa. A gwajin bidiyo, yanayin fitarwa yana canzawa idan shigarwa ya faɗi ƙasa da yawa.
• Babban fitarwa = ƙarancin wutar fitarwa da ake samu: ƙara wutar lantarki ba “kyauta” ba ne. Yayin da ƙarfin lantarki ya tashi, wutar fitarwa da ake samu tana raguwa don wannan ƙarfin shigarwa.
• Zafi shine ainihin mai iyakancewa: a babban nauyi IC yana yin zafi sosai, fitarwa tana raguwa, kuma module na iya kashe kansa.

Inganci: Abin Da Za Ku Yi Tsammani

Dangane da lanƙwan takardar bayanai da aka tattauna a bidiyon, inganci yana da kyau sosai a matsakaicin wutar lantarki kuma yana raguwa yayin da wutar lantarki ke ƙaruwa. Misalin lanƙwan da aka ambata ya nuna kusan:

• Inganci mai kyau sosai a kusan ɗari kaɗan na milliamps (yankin misali kusa da ~200mA). 
• Inganci yana faɗuwa zuwa sama da 80% yayin da wutar lantarki ke kusantar ~800mA da sama. 

A gina na gaske, ku sa tsammaninku a zahiri: shimfidawa, sanyaya, rabon ƙarfin lantarki, da nauyi duk suna shafar inganci da kwanciyar hankali.

Sakamakon Gwajin Nauyi Na Gaskiya (Abin Da Yayi Aiki Da Gaske)

Mafi amfani ɓangaren bidiyon shine gwajin damuwa na gaske ta amfani da electronic load. Ga mahimman sakamako:

Gwaji 1: 9V Shigarwa → 12V Fitarwa

• A ~1A fitarwa: fitarwa ta tsaya kusa da 12V kuma module ya kasance mai amfani.
• A ~2A fitarwa: fitarwa ta ragu (kusan ƙananan 11V) kuma chip ɗin ya yi zafi ƙwarai da ba za a iya taɓa shi ba—aikin bai kasance abin dogaro ba. 

Ƙarshe: 9→12V a ~1A yana da kyau; tura zuwa 2A ba a ba da shawarar ba sai da sanyaya mai ƙarfi kuma ko da haka na iya zama marar kwanciyar hankali.

Gwaji 2: 3.3V Shigarwa → 5V Fitarwa

• A ~1A fitarwa: ya yi sanyi kuma ya yi kama da barga a gwajin.
• A ~2A fitarwa: ƙarfin lantarki ya faɗi sosai kuma gwajin ya gaza / yanayin kashewa ya bayyana. 

Ƙarshe: ƙara 3.3V zuwa 5V a ~1A abu ne mai yiwuwa; ƙoƙarin 2A ba abin dogaro ba ne.

Gwaji na 3: 12V Shigar → 24V Fitarwa

• A mafi girman halin kaya (kusan kewayon amp), ƙarfin fitarwa ya faɗi ƙasa da 24V kuma zafi ya zama babbar matsala. 
• A ~0.5A fitarwa: fitarwa ya kasance kusa da 24V kuma an ɗauke shi a matsayin yanayin “nasara” a cikin bidiyon. 

Ƙarshe: 12→24V abu ne mai yiwuwa, amma ka ɗauki ~0.5A a matsayin yankin aiki mafi aminci.

Don haka… Shin Da Gaske ne Mai Ƙara “2A / 3A”?

A aikace, wannan module ya kamata a ɗauke shi a matsayin ƙaramin, mai rahusa mai ƙara ƙarfi don matsakaicin iko. Allon na iya aiki da kyau idan ka kiyaye halin yanzu a matsayin mai ma'ana kuma rabon ƙarfin lantarki ya zama mai yiwuwa. Amma idan ka matsa shi sosai, faɗuwar ƙarfin lantarki + matsanancin zafi suna bayyana da sauri.

Daga taƙaitaccen bidiyon, misalan aiki masu amfani sune:

• 3.3V → 5V a ~1A 
• 9V → 12V a ~1A 
• 12V → 24V a ~0.5A

Inda Wannan Module Yake Da Amfani

• Ƙara 5V USB har zuwa 9V ko 12V don ƙananan ayyukan lantarki
• Ƙarfafa na'urorin da ke buƙatar mafi girman ƙarfin lantarki amma matsakaicin halin yanzu (na'urori masu auna, relays ƙanana, kaya masu sauƙi)
• Saurin ƙirƙira samfuri lokacin da kake buƙatar fitarwa mai daidaitacce kuma ba ka son tsara cikakken samar da wutar lantarki

Muhimman Shawarwari na Tsaro & Aiki

• Kada ka amince da iƙirarin babban halin yanzu ba tare da gwada takamaiman kayanka da ƙara sanyaya ba.
• Duba zafin jiki: idan IC yana ƙonewa da zafi, ja da baya—zafi yawanci yana nufin faɗuwar ƙarfin lantarki da haɗarin gazawa.
• Auna da ingantaccen mita: bidiyon ya lura da rashin daidaiton mita akan karatun shigarwa; koyaushe ka tabbatar da ingantaccen multimeter.
• Fara ƙasa ka daidaita a hankali: pots masu juyawa da yawa na iya ɗaukar juyi da yawa kafin fitarwa ya canza. 

Takaitaccen Nunin (Abin Da Kake Gani a Bidiyon)

• Daidaita ƙarfin lantarki na farko da nuna matsakaicin fitarwa kusa da babban kewayon 20V. 
• Daidaitaccen tsari lokacin da shigarwa ya tsaya kuma an saita fitarwa (misali: saita fitarwa 12V). 
• Gwajin kayan lantarki yana nuna lokacin da module ya tsaya barga da lokacin da ya yi zafi sosai ya faɗi. 

Abubuwa & Takardun Bayanai

Kana iya samun module da abubuwa masu alaƙa ta amfani da hanyoyin haɗin gwiwa a ƙasan wannan labarin. Don zurfafa halayen lantarki, koma zuwa takardun bayanan MT3608 (kuma an haɗa su a ƙasa idan an bayar) don fahimtar halayen inganci da iyakokin aiki a cikin kewayon ƙarfin lantarki/halin yanzu naka.
