I-voltage eqhubekayo kanye nemojuli yamandla e-othomathikhi eguquguqukayo eguqukayo yamanje I-Booster module Ukushaja i-Solar 4A

Izici zomkhiqizo
Ukufakwa kwe-voltage ebanzi engu-5-30V, ukuphuma kwe-voltage ebanzi 0.5-30V, kokubili i-boost ne-buck, njengokuthi ulungisa i-voltage ephumayo ibe ngu-18V, khona-ke i-voltage yokufaka phakathi kwezinguquko ezingahleliwe ezingu-5-30V, izoba okukhipha njalo kwe-18V; Isibonelo, ufaka i-12V, lungisa i-potentiometer isethi engu-0.5-30V okukhiphayo okungahleliwe.
Amandla aphezulu, ukusebenza kahle okuphezulu, ukusebenza okungcono kunesixazululo se-XL6009/LM2577. I-MOS yangaphandle engu-60V75A yamandla aphezulu isetshenziswa futhi ihlanganiswe ne-high-current and high-voltage high-voltage Schottky diode SS56. Ayiqhathanisi ne-SS34 yezinhlelo ze-6009 noma ze-2577, ngoba ngokomgomo we-voltage ekhuphukayo noma ewayo, ukumelana nomthamo we-MOS ne-Schottky mkhulu kunesamba se-voltage yokufaka nokuphumayo.
I-iron silicon aluminium magnetic ring inductance, ukusebenza kahle okuphezulu. Akukho ukushaya ikhwela kumodi yamanje engashintshi.
Usayizi wamanje ungasethelwa ukukhawulela ukuphuma kwamanje, idrayivu yamanje engaguquki, nezibani zokushaja ibhethri.
Ngomsebenzi wayo wokukhipha i-anti-back-flow, asikho isidingo sokwengeza i-anti-back-flow diode uma ushaja ibhethri.
Imiyalo yokusetshenziswa
1. Isetshenziswa njengemojula ye-booster evamile enokuvikelwa kwamanje
Isetshenziswa kanjani:

(1) Lungisa i-CV njalo i-voltage potentiometer ukuze i-voltage ephumayo ifinyelele inani le-voltage oyifunayo
(2) Linganisa ukuphuma kwe-short-circuit current ngesitobhi samanje esinamamitha amaningi angu-10A (xhuma ngokuqondile amapeni amabili ekugcineni kokukhiphayo), bese ulungisa i-CC engaguquki i-potentiometer ukuze wenze okukhiphayo kufinyelele inani lokuvikela elinqunywe ngaphambili. . (Isibonelo, inani lamanje elikhonjiswa yi-multi-meter ngu-2A, khona-ke amandla aphezulu angafinyelela ku-2A kuphela uma usebenzisa imodyuli, futhi inkomba yamanje ebomvu engaguquki yamanje ivuliwe lapho yamanje ifinyelela ku-2A, ngaphandle kwalokho inkomba icishiwe)
Qaphela: Uma isetshenziswa kulesi simo, ngoba okukhiphayo kunokumelana kwesampula kwamanje kwe-0.05 Ohm, kuzoba nokwehla kwe-voltage engu-0 ~ 0.3V ngemva kokuxhuma umthwalo, okujwayelekile! Lokhu kwehla kwamandla kagesi akudonselwa phansi umthwalo wakho, kodwa kuze kufike ekumelaneni namasampula.

2. Sebenzisa njengeshaja yebhethri
Imojula engenawo umsebenzi wamanje oqhubekayo ayikwazi ukusetshenziselwa ukushaja ibhethri, ngoba umehluko wengcindezi phakathi kwebhethri neshaja mkhulu kakhulu, okuholela ekushajweni kwamanje okudlulele, okuholela ekulimaleni kwebhethri, ngakho ibhethri kufanele lisetshenziswe ekuqaleni kwebhethri. ukushaja njalo wamanje, lapho ukushaja ngezinga elithile, ukushintsha okuzenzakalelayo emuva njalo voltage ukushaja.

Isetshenziswa kanjani:
(1) Thola amandla kagesi eshaja antantayo kanye namandla okushaja ebhethri okudingeka uyishaje; (Uma ipharamitha yebhethri ye-lithium ingu-3.7V/2200mAh, khona-ke i-voltage yokushaja entantayo ingu-4.2V, kanti amandla amakhulu okushaja angu-1C, okungukuthi, 2200mA)
(2) Ngaphansi kwezimo zokungalayishi, i-multi-meter ikala i-voltage ephumayo, futhi i-potentiometer ye-voltage engashintshi iyalungiswa ukuze i-voltage ephumayo ifinyelele ku-voltage yokushaja entantayo; (Uma ushaja ibhethri le-lithium elingu-3.7V, lungisa amandla kagesi abe ngu-4.2V)
(3) Linganisa ukuphuma kwe-short-circuit current nge-multi-meter 10A stop current (xhuma ngokuqondile amapeni amabili ekugcineni kokuphumayo), futhi ulungise i-potentiometer yamanje eqhubekayo ukuze wenze okukhiphayo kufinyelele inani lamanje lokushaja elinqunywe kusengaphambili;
(4) Umsinga wokushaja ozenzakalelayo uphindwe izikhathi ezingu-0.1 kunamanje wokushaja; (Amandla ebhethri enqubweni yokushaja ayancishiswa kancane kancane, kancane kancane asuke ekushajweni njalo kuya eshajani yamandla kagesi njalo, uma ukushaja kusethelwe ku-1A, bese kuthi lapho ukushaja kungaphansi kuka-0.1A, ukukhanya okuluhlaza okwesibhakabhaka kuvaliwe, okuluhlaza okotshani. ukukhanya kuvuliwe, ngalesi sikhathi ibhethri lishajwe)
(5) Xhuma ibhethri bese uyishaja.
(Izinyathelo 1, 2, 3, 4 yilezi: isiphetho sokufaka sixhunywe kugesi, futhi isiphetho esiphumayo asixhunyiwe kubhethri.)
3. Isetshenziswa njengemojula yomshayeli wamanje wamandla aphezulu we-LED
(1) Nquma i-voltage yokusebenza yamanje nephezulu oyidingayo ukushayela i-LED;
(2) Ngaphansi kwezimo zokungalayishi, i-multi-meter ikala i-voltage ephumayo, futhi i-potentiometer engaguquguquki iyalungiswa ukuze i-voltage ephumayo ifinyelele ku-voltage ephezulu yokusebenza ye-LED;
(3) Sebenzisa i-multi-meter 10A yamanje ukuze ulinganise ukuphuma kwe-short-circuit current, futhi ulungise i-potentiometer yamanje engashintshi ukuze wenze ukuphuma kwamanje kufinyelele i-LED enqunywe kusengaphambili yamanje;
(4) Xhuma i-LED futhi uhlole umshini.
(Izinyathelo 1, 2, no-3 yilezi: okokufaka kuxhunywe kugesi, okukhiphayo akuxhumekile ekukhanyeni kwe-LED.)
