Umbane othe rhoqo kunye nemodyuli ye-booster eguqukayo yangoku eguqukayo yangoku yemodyuli yokunyusa i-Solar ukutshaja i-4A

Iimpawu zemveliso
Igalelo lombane obanzi 5-30V, i-voltage ebanzi ye-0.5-30V, zombini i-boost kunye ne-buck, njengokuba ulungelelanisa i-voltage ephumayo kwi-18V, ngoko i-voltage yegalelo phakathi kwe-5-30V yokutshintsha okungahleliweyo, iya kuba yimveliso eqhubekayo ye-18V; Umzekelo, ufaka i-12V, lungisa i-potentiometer iseti ye-0.5-30V imveliso engafanelekanga.
Amandla aphezulu, ukusebenza kakuhle, ukusebenza okungcono kuneXL6009/LM2577 isisombululo. I-60V75A yangaphandle ye-MOS ephezulu yamandla isetyenziswa kwaye idibene ne-high-current and high-voltage Schottky diode SS56. Ayinakuthelekiswa ne-SS34 ye-6009 okanye i-2577 izikimu, kuba ngokomgaqo wokunyuka kunye nokuhla kwamandla ombane, i-voltage resistant ye-MOS kunye ne-Schottky inkulu kunesixa segalelo kunye nesiphumo sombane.
Iron silicon aluminiyam inductance magnetic ring, ukusebenza kakuhle. Akukho kubethwa umlozi kwimo eqhubekayo yangoku.
Ubungakanani bangoku bunokusetwa ukunciphisa imveliso yangoku, idrive eqhubekayo, kunye nezibane zokutshaja ibhetri.
Ngomsebenzi wayo wokukhupha umva wokuchasa umva, akukho mfuneko yokongeza i-anti-back-flow diode xa utshaja ibhetri.
Imiyalelo yokusetyenziswa
1. Isetyenziswe njengemodyuli ye-booster eqhelekileyo kunye nokhuseleko lwangoku
Kusetyenziswa kwanjani:

(1) Lungisa i-CV engaguqukiyo i-potentiometer yombane ukuze amandla ombane aphumeyo afikelele kwixabiso lombane olifunayo
(2) Ukulinganisa imveliso ye-short-circuit yangoku kunye ne-multi-meter 10A yokumisa okwangoku (ukudibanisa ngokuthe ngqo iipeni ezimbini ukuya ekupheleni kwemveliso), kwaye ulungelelanise i-CC eqhubekayo ye-potentiometer yangoku ukwenza imveliso yangoku ifikelele kwixabiso lokukhusela elichazwe kwangaphambili. . (Umzekelo, ixabiso langoku elibonakaliswe yi-multi-meter yi-2A, ngoko umbane ophezulu unokufikelela kuphela kwi-2A xa usebenzisa imodyuli, kwaye isalathisi esibomvu esihlala sihlala sikhona xa ikhoyo ifikelela kwi-2A, ngaphandle koko isalathisi cima)
Qaphela: Xa isetyenziswe kule meko, ngenxa yokuba isiphumo sinokuchasana kwesampulu yangoku ye-0.05 Ohm, kuya kubakho ukuhla kwe-voltage ye-0 ~ 0.3V emva kokudibanisa umthwalo, okuqhelekileyo! Oku kuhla kwamandla ombane akutsalwa phantsi ngumthwalo wakho, kodwa ukuya kuxhathiso lwesampulu.

2. Sebenzisa njengetshaja yebhetri
Imodyuli ngaphandle komsebenzi oqhubekayo wangoku ayinakusetyenziselwa ukutshaja ibhetri, kuba umahluko woxinzelelo phakathi kwebhetri kunye netshaja inkulu kakhulu, okukhokelela ekutshajweni okugqithisileyo kwangoku, okukhokelela kumonakalo webhetri, ngoko ke ibhetri kufuneka isetyenziswe ekuqaleni kwebhetri. ukutshaja okuzingileyo kwangoku, xa kutshaja ukuya kuthi ga kwinqanaba elithile, ukutshintshela okuzenzekelayo ukubuyisela ukutshaja ombane rhoqo.

Kusetyenziswa kwanjani:
(1) Qinisekisa umbane wentlawulo edadayo kunye nomsinga wokutshaja webhetri ekufuneka uyitshaje; (Ukuba iparamitha yebhetri ye-lithium yi-3.7V / 2200mAh, i-voltage yokutshaja edadayo yi-4.2V, kwaye i-charge yangoku enkulu yi-1C, oko kukuthi, i-2200mA)
(2) Phantsi kweemeko zokungathwali mthwalo, iimitha ezininzi zilinganisa umbane ophumayo, kwaye i-potentiometer yombane engaguqukiyo iyahlengahlengiswa ukwenza umbane ophumayo ufikelele kumbane wentlawulo edadayo; (Ukuba uhlawulisa ibhetri ye-lithium eyi-3.7V, lungisa umbane wokuphuma kwi-4.2V)
(3) Ukulinganisa imveliso ye-short-circuit current kunye ne-multi-meter 10A yokuyeka ngoku (ukudibanisa ngokuthe ngqo iipeni ezimbini ukuya ekupheleni kwemveliso), kwaye ulungelelanise i-potentiometer yangoku ukuze wenze imveliso yangoku ifikelele kwixabiso elimiselweyo lokutshaja langoku;
(4) Umsinga wokutshaja ongagqibekanga ngu-0.1 ngokuphindwe kabini kumsinga wokutshaja; (Ibhetri ekhoyo kwinkqubo yokutshaja iyancitshiswa ngokuthe ngcembe, ngokuthe ngcembe ukusuka kwi-charge yangoku ukuya kwi-voltage etshaja rhoqo, ukuba umjelo wokutshaja usetelwe ku-1A, emva koko xa umjelo wokutshaja ungaphantsi kwe-0.1A, ukukhanya okuluhlaza kucinyiwe, uhlaza ukukhanya kulayitiwe, ngeli xesha ibhetri igcwalisiwe)
(5) Qhagamshela ibhetri uze uyitshaje.
(Amanyathelo 1, 2, 3, 4: isiphelo segalelo siqhagamshelwe kunikezelo lwamandla, kwaye isiphelo sokuphuma asiqhagamshelwanga kwibhetri.)
3. Isetyenziswe njengemodyuli yangoku yomqhubi we-LED enamandla aphezulu
(1) Ukugqiba ukusebenza kwangoku kunye nombane osebenzayo ophezulu ofunekayo ukuqhuba i-LED;
(2) Phantsi kweemeko zokungabikho komthwalo, iimitha ezininzi zilinganisa umbane ophumayo, kwaye i-potentiometer ye-voltage engatshintshiyo ihlengahlengiswa ukwenza umbane ophumayo ufikelele kumbane ophezulu wokusebenza we-LED;
(3) Sebenzisa i-multi-meter 10A yangoku ukulinganisa imveliso ye-short-circuit current, kwaye ulungelelanise i-potentiometer yangoku ukuze wenze imveliso yangoku ifikelele kwi-predetermined LED yangoku yokusebenza;
(4) Qhagamshela i-LED kwaye uvavanye umatshini.
(Amanyathelo 1, 2, kunye ne-3 ngala: igalelo liqhagamshelwe kunikezelo lwamandla, imveliso ayiqhagamshelwanga kwisibane se-LED.)
