Ungakhanyisa kanjani isibani sokukhanya esingu-12V nge-transistor?

Ukukhanyisa kuyisici esibalulekile ezinhlelweni eziningi zikagesi. Ngalesi sizathu, kubalulekile ukwazi ukuthi ukhanyisa kanjani isibani esingu-12 V usebenzisa i-transistor. Ama-Transistors ngamadivayisi kagesi asetshenziselwa ukukhulisa noma ukushintsha amasignali kagesi. Kulesi sihloko, sizohlola inqubo yesinyathelo ngesinyathelo yokukhanyisa isibani se-12 V ngokusebenzisa i-transistor, ngaleyo ndlela sinikeze isisombululo esiphumelelayo nesisebenzayo sokukhanyisa amaphrojekthi ahlukene noma amasekhethi kagesi.

Ngaphambi kokuqala, kubalulekile ukucabangela izinto ezilandelayo ezidingekayo kanye nezingxenye: i-12 V isibani, i-NPN transistor, i-base resistor, i-12 V amandla kagesi, izintambo zokuxhuma kanye ne-breadboard ukwenza uxhumano. indlela ephephile ⁢futhi ihlelekile. Lezi zingxenye zizoqinisekisa ukusebenza okulungile futhi zizovumela isibani ukuthi sikhanyise kahle.

Isinyathelo sokuqala ukukhomba ukuxhumana kwe-transistor. Ku-NPN transistor, amatheminali amathathu angabonwa: i-emitter, isisekelo kanye nomqoqi. I-base resistor ixhunywe kutheminali eyisisekelo ye-transistor ukuze kulawulwe ukugeleza kwamandla phakathi kwe-emitter nesiqoqi. Kubalulekile ukuqinisekisa ukuthi izintambo ezixhumayo ⁢zixhunywe kahle kutheminali ngayinye ukuze kuqinisekiswe ukusebenza kahle kwe-transistor.

Ngemuva kokuqinisekisa ukuxhumana kwe-transistor, kuyadingeka ukuxhuma isibani se-12V kumandla kagesi. Ukuze wenze lokhu, kufanele uxhume i-terminal evumayo yokunikezwa kwamandla kumqoqi we-transistor kanye netheminali engalungile komunye wemikhawulo yesibani. Esinye isiphetho se-bulb sixhunywe ku-emitter ye-transistor. ⁤Lokhu kulungiselelwa kuzovumela ukugeleza okwanele kwamanje ukuze uvule isibani lapho i-transistor isebenza.

Ekugcineni, sekuyisikhathi sokuvula i-transistor ukuze uvule isibani esingu-12V. Lokhu kufezwa ngokusebenzisa isignali yokulawula esisekelweni se-transistor Ukuvula isignali yokulawula kuvumela ukugeleza kwamanje kusuka ku-emitter kuya kumqoqi, ngaleyo ndlela kugcwalise isifunda nokuvula isibani sokukhanya khumbula ukuthi i-transistor kufanele yenziwe isebenze kahle ngokulandela izicaciso zomkhiqizi futhi igweme ukweqa umkhawulo wamanje omkhulu.

Ngokulandela lezi zinyathelo ngokucophelela, singakhanyisa isibani esingu-12 V sisebenzisa i-transistor ngempumelelo futhi iphephile. Lesi sixazululo singasetshenziswa kumaphrojekthi ahlukahlukene noma izifunda ze-elekthronikhi ezidinga ukukhanya, ngaleyo ndlela zinikeze inketho ethembekile nephumelelayo. Ukuxhumana okulungile nokucushwa kwezingxenye kuzoba yisihluthulelo sokufeza ukusebenza kahle nokugwema ukulimala okungenzeka ezingxenyeni noma isifunda ngokujwayelekile.

- Isingeniso sokukhanyisa isibani esingu-12 V nge-transistor

Kulokhu okuthunyelwe, sizochaza ngokuningiliziwe indlela yokukhanyisa isibani se-12 V usebenzisa i-transistor. Ukukhanyisa isibani nge-transistor Kuyinqubo evame ukusetshenziswa kumaphrojekthi kagesi futhi angahlinzeka a indlela ephumelelayo futhi kuphephile ukulawula ukugeleza kwamanje. Ngezansi, sikunikeza umhlahlandlela Igxathu emvakwe gxathu mayelana nendlela yokukufeza.

Isinyathelo 1: Okokuqala okufanele ukwenze ukuqoqa izinto ezidingekayo. Ukuze unike amandla i-bulb ye-12V, uzodinga i-NPN transistor, isixhasi samanje esikhawulelayo, ugesi ongu-12V, kanye ne-bulb ngokwayo. Qiniseka ukuthi unazo zonke lezi zingxenye esandleni ngaphambi kokuqala ukuhlanganisa.

Isinyathelo 2: ⁢ Uma usuqoqe izinto zokwakha, sekuyisikhathi sokuxhuma isekethe. Okokuqala, xhuma isigxobo esihle sokunikezwa kwamandla kumqoqi we-transistor.
