Eli nqaku liza kunikezelwa kwenye entsha icandelo elektroniki ukongeza kuluhlu. Isixhobo onokudibanisa neebhodi zophuhliso, ezinje nge Arduino. Kwakhona, ukuba ufuna ukwazi ngakumbi malunga ne- a Isiguquli seDC DC, Apha ungafunda yonke into ebalulekileyo malunga nale setyhula, ukusuka kule nto iyiyo, ukuba isebenza njani kunye nokusetyenziswa kwayo.
Njengoko ubona, isixhobo ayitshintshi isuke kolunye uhlobo lwangoku iye kolunye, njengoko unikezelo lwamandla, kwaye oko kunokuba nokufana nezinye izinto abalawuli bevolthi, kuba iyakuguqula ngokuchanekileyo obu bukhulu ...
Yintoni isiguquli seDC DC?
Un Isiguquli seDC-DC Luhlobo lwesiguquli oluza kuguqula ukusuka ngqo ngqo kuye kuthi ngqo ngoku, kodwa kwinqanaba levolthi eyahlukileyo. Oko kukuthi, ayiguquli phakathi kweentlobo zangoku, iguqula kuphela inqanaba lombane. Ukongeza, zizekethe ezithandwayo kakhulu kwi-elektroniki (iirobhothi, iidroni, izinto zombane, izithuthi zombane, iitshaja, ...).
Abaguquli beDC DC baya kugcina amandla engena kwindawo yokugcina izinto yethutyana kwaye emva koko bayakuyithumela kwindawo evulekileyo eyahlukileyo yombane. Ukuze kwenzeke oku, kufuneka kusetyenziswe ugcino lwentsimi enemagnethi enje ngee inductors okanye ugcino lwentsimi yombane ezinje ngee capacitors. Ngelixa uqhuba ukutshintshwa, ii-transistors, ii-diode, njl. Ziyasetyenziswa.
Umzekelo, kunokuba yinto eqhelekileyo ukufumana Abaguquleli beDC DC, ene-LM2596 enokuba negalelo eliqhelekileyo le-4.5v ukuya kuthi ga kwi-40v DC kunye nokuphuma kwe-1.23 ukuya kwi-37v DC.
Abanye abaguquli beDC DC bavumela amandla ukuba agqithiselwe ezokubhaliweyoUkulungiselela le nto, ii-diode zabaguquli abaqhelekileyo zithathelwa indawo ngabazimeleyo abazilawulayo. Olu olunye uhlobo lokuguqula lusetyenziselwa ezinye iinkqubo ezinje ngokuhlaziya iziqhoboshi zesithuthi okanye i-KERS.
Ngokubhekisele kwifomathi, uya kuyifumana ngohlobo lwe iisekethe ezidibeneyoUkongeza, zinokuza zikwimo yemodyuli, kunye nezinye izinto ezongeziweyo ukubenza basebenze ngakumbi kwaye banokusetyenziswa ngendlela elula.
Iindidi zabaguquli
Kukho ezahlukileyo Iindidi zabaguquleli beDC DC, Kuxhomekeke kubuchwephesha bayo. Ezona zixhaphakileyo zezi:
- IBHAKI: yeyona ilula kwaye ixhaphake kakhulu. Inendawo yegalelo kunye nemveliso kunye, ke ngoko, ayinasiphumo sodwa kwigalelo. Imveliso yombane iya kuba ngaphantsi, kunye ne-polarity efanayo neyegalelo.
- Ikheshi (Ukunyusa) : kolunye uhlobo lwesiguquli seDC DC, umbane wokuphuma uhlala uphezulu kunevolthi yokufaka. Oko kukuthi, inyusa i-voltage endaweni yokunciphisa. Imveliso ayihlukaniswanga kwigalelo nokuba, kuba banomhlaba kunye. Ingxaki kukuba awukwazi ukunciphisa umda wokuphuma ngoku kwikhompyutha.
- Ukubuyela umva okanye ukubuyela umva (Ukubuyela umva): Umbane wokuphuma unokuba sezantsi kwaye uphakame kunegalelo lombane, kodwa ngokubuyela umva kumlinganiso. Luhlobo lwesiguquli olunokuba negalelo kwimveliso okanye hayi. Kwezi zibekelwe bucala, senziwa sombane.
- Ngqo (Phambili): isebenza ngokufanayo neBuck, kodwa ine-transformer esebenza njengokususa ubushushu phakathi kwegalelo kunye nemveliso, ekwaziyo ukwenza iziphumo ezininzi kunye nevolthi ephezulu kunegalelo, kuxhomekeke kukujija kwesibini.
- Ukutyhala-tyhala (PUSH-PULL): isebenzisa iitransistors kwigalelo lokuqala, ukwenza umtshangatshangatshangatshangatshangatshangatshanganayo, kunye nee-diode kwisekondari, ukufezekisa ukulungiswa kwamaza kabini.
- Ibhulorho: Ekujikeni kwesekondari kuyafana nokusongelwa kokutsalwa, kodwa kwiziko lokuqala lenza umjelo olinganayo kunye neebhulorho ezine zebhulorho ezisebenza ngambini.
- Isiqingatha seBhulorhoUkwenza lula i-DC DC yokuguqula ibhulorho, ine-transistors ezimbini kunye ne-capacitors ezimbini kwiziprayimari.
Ukuthenga phi isiguquli seDC DC yeArduino
Ungafumana uninzi lweefomathi kunye neendidi zabaguquleli beDC DC ukuze ubabandakanye kwiiprojekthi zakho. Ziyafumaneka kuwe kwiivenkile ezikhethekileyo kwizinto ze-elektroniki, okanye nakumaqonga amakhulu akwi-Intanethi afana neAmazon. Ukuba ufuna enye yezi ziguquli, nantsi apha iingcebiso ezithile:
- Adjustable DC DC Buck Lenxnmy Converter kunye LM2596S kwimodyuli. Ibandakanya iscreen esine-voltmeter ukubonisa amaxabiso.
- Yizhet iziqwenga ezi-5 zesiguquli seDC DC nge-LM2596 kwimodyuli.
