Lo mbhalo uzonikezelwa kokunye okusha ingxenye kagesi engezwa ohlwini. Idivayisi ongayihlanganisa namabhodi entuthuko, njenge I-Arduino. Futhi, uma udinga ukwazi okwengeziwe ngalokho a Isiguquli seDC DC, lapha ungafunda konke okubalulekile ngalesi sifunda, ukusuka kulokho okuyikho, ukuthi kusebenza kanjani kanye nokusetshenziswa kwayo.
Njengoba ukwazi ukubona, idivayisi ukuthi ayiguquki isuka kolunye uhlobo lwamanje iye kolunye, njenge amandla kagesi, futhi lokho kungahle kufane nezinto ezithile abalawuli bamandla kagesi, ngoba izobuguqula kahle lobu bukhulu ...
Yini isiguquli seDC DC?
Un Isiguquli se-DC-DC Luhlobo lwesiguquli esizoguquka sisuke kumanje siqonde kolunye oluqondile, kepha ngezinga lamandla ahlukile. Okungukuthi, ayiguquli phakathi kwezinhlobo zamanje, iguqula kuphela izinga lamandla. Ngaphezu kwalokho, amasekethe athandwa kakhulu ku-elektroniki (amarobhothi, ama-drones, amandla kagesi, izimoto zikagesi, amashaja, ...).
Lezi zinguquko zeDC DC izogcina amandla lokho kungena endaweni yokugcina impahla yesikhashana bese beyiletha esitolo esidayisa ngamandla ahlukile. Ukuze lokho kwenzeke, kufanele kusetshenziswe isitoreji sensimu kazibuthe njengama-inductors noma isitoreji senkambu kagesi njengama-capacitors. Ngenkathi kwenziwa uguquko, ama-transistor, ama-diode, njll.
Isibonelo, kungajwayelekile ukuthola Abaguquli beDC DC, ene-LM2596 engaba nokufaka okujwayelekile okungu-4.5v kuze kufike ku-40v DC bese kukhishwa u-1.23 kuye ku-37v DC.
Abanye abaguquli beDC DC bavumela ukudluliswa kwamandla kufayela le- okokubhidaNgalokhu, ama-diode wabaguquli abajwayelekile athathelwa indawo ngabashintshi abazilawulayo abazimele. Lolu hlobo lokuguqulwa lusetshenziselwa ezinye izinhlelo ezinjengamabhuleki emoto avuselelayo noma ama-KERS.
Ngokuqondene nefomethi, uzothola kuzo ngendlela ye- ama-circuits ahlangeneFuthi zingeza ngesimo semodyuli, kufakwe ezinye izinto ukuzenza zisebenze kakhudlwana nokuthi zingasetshenziswa ngendlela elula.
Izinhlobo zabaguquli
Kukhona okuhlukile izinhlobo ze-DC DC converters, kuya ngemininingwane yayo. Okuvame kakhulu yilezi:
- IMALI: ilula kakhulu futhi imvamisa ivame kakhulu. Inendawo yokufaka kanye neyokukhipha ndawonye, ngakho-ke, ayinakho okukhiphayo okuhlukanisiwe kokufakwayo. Amandla okukhipha azoba phansi, futhi abe nobumbano obufanayo nobokufaka.
- I-Elevator (Ukukhuthaza) : kolunye uhlobo lwesiguquli seDC DC, amandla okukhipha ahlala ephakeme kunamandla wokufaka. Lokho wukuthi, kukhulisa i-voltage esikhundleni sokuyinciphisa. Okukhiphayo nakho akuhlukanisiwe kokufaka, ngoba banomhlaba ndawonye. Inkinga ukuthi awukwazi ukukhawulela okukhiphayo okwamanje ngekhompyutha.
- Buyela emuva noma uhlehlise (i-Flyback): i-voltage yokukhipha ingaba ngaphansi nangaphezulu kune-voltage yokufaka, kepha nge-polarity ehlehlisiwe. Luhlobo lwesiguquli singaba nokufaka okukhiphayo kokukhiphayo noma cha. Kulezo ezihlukanisiwe, kwenziwa nge-transformer.
- Ngqo (Phambili): isebenza ngokufana neBuck, kepha ine-transformer esebenza njengokwehlukanisa phakathi kokufakwayo nokukhiphayo, ikwazi ukwenza imiphumela eminingi futhi ibe namandla kagesi aphezulu kunalawo wokufaka, ngokuya ngamawindi wesibili.
- Phusha-donsa (PUSH-PULL): isebenzisa ama-transistors ekufakweni kweprayimari, okwenza igagasi elilinganayo, nama-diode kwesekondari, kuzuzwe ukulungiswa kwamaza kabili.
- Ibhuloho: ekushayweni kwesibili kuyafana nokugudluzwa kwe-push-pull, kepha ekushayweni okuyinhloko kwenza igagasi lokulinganisa ngama-transistor amane ebhuloho asebenza ngababili.
- IHalf-Bridge: ukwenziwa lula kwesiguquli se-DC DC, esinama-transistor amabili nama-capacitors amabili kuprimary.
Ungayitholaphi i-DC DC converter ye-Arduino
Ungathola inqwaba yamafomethi nezinhlobo zabaguquli beDC DC ongazifaka kumaphrojekthi wakho. Ziyatholakala kuwe ezitolo ezikhethekile ezintweni ze-elekthronikhi, noma futhi kuzingxenyekazi ezinkulu eziku-inthanethi ezifana ne-Amazon. Uma udinga omunye walaba baguquli, nakhu uya izincomo ezithile:
- I-DC DC Buck Lenxnmy Converter eguquguqukayo ene-LM2596S kumodyuli. Kufaka isikrini esine-voltmeter ukukhombisa amanani.
- Izicucu ze-Yizhet 5 zesiguquli se-DC DC nge-LM2596 kumodyuli.
- I-AZDelivery XL4016 Arduino ehambelana ne-DC DC converter ne-eBook ifakiwe.
