Yintoni injongo yamandla amaninzi kwi-chipUkunikezwa AmandlaIzikhonkwane?
Njengoko iinjineli ze-elektroniki ziyaziwa ukuba amandla asebenzela imisebenzi emine yokuqala: Ukucofa, ukudibanisa (ukufaka i-DC ngelixa uvumela i-AC), ukuguqula, kunye nokugcinwa kwamandla. Namhlanje, ndiza kugxila ekucaciseni umsebenzi wokuhombisa.
Iindidi eziqhelekileyo zokwenza amachaphaza axhonyiweyo
Lo mfanekiso ungentla ubonakalisa isikimo esiyinxalenye ye-stm32 uthotho stecontroller incinci yokuhambisa amandla. Le Mcu ifuna iindlela ezintlanu ze-3.3v, ezithi zinikezelwa yi-ldom (yomlawuli ophantsi we-ropout), njenge-LM11117.
Isizathu sokuba i-DecoupitSovars ifuneka
Ngelixa i-LDSS ngokubanzi ibonelela ngeevolda ezizinzileyo ezithelekiswa nazoAbaguquleli be-DC. Ukujongana nale nto, sibeka i-decoupling i-capacitors kufutshane ne-pins ye-chip. Ezi caphitor zifumana ingxolo enkulu ye-CARCHEARD ukusuka kubonelelo lwamandla, ziphambukise emhlabeni, ngaloo ndlela ziqinisekisa ukuba i-chip ifumana i-voltage ethembekileyo nethembekileyo ye-DC. Ngentsebenzo egqibeleleyo, i-decoupling ye-capacitors kufuneka ibekwe kufutshane kangangoko kunokwenzeka kwizikhonkwane zeChip.
Kutheni le nto i-0.1μf camciter isetyenziswa?
Xa sifunda inkohliso yamandla, sihlalutya isakhono esinje, kwiindlela ezisezantsi, iCapaci isebenze ngokuyintloko njengecebo lokucoca. Nangona kunjalo, njengoko i-frequency inyuka, icandelo elingenamsebenzi le-capacitor libaluleke kwaye ekugqibeleni lilawule. Ngaphandle komgquba othile wezantya, ukucocwa kwe-capacioring ye-capacioring kuyancipha. Oku kuthetha ukuba kwiIzantya eziphezulu, unyango alusasebenzi 'njengeCapaci "elinyulu". Eyona mizobo yokucoca i-capacitor iboniswe kwi-curve engezantsi:
Ukusuka kwijika, ukucocwa okufanelekileyo kwenzeka kwindawo esezantsi yeukunyanzelaijika (ubuncinci bomgangatho). Nangona kunjalo, ngokunyuka rhoqo, i-0.1μt ye-canocitor ayisebenzi kakuhle xa kuthelekiswa ne-0.01μ8 ye-intanethi. Kwiindlela eziphezulu zawomileyo, amaxabiso amancinci amancinci (umz.
Isisombululo: I-AChollel ye-capacitors
Ukujongana nale sithintelo, uyilo oluninzi lwesekethe lusebenzisa amandla amaninzi ngokuhambelana nexabiso lamandla ahlukeneyo. Ngokudibanisa amandla amaxabiso ahlukeneyo, uluhlu olusebenzayo lokucoca lwandisiwe, uqinisekisa ukucinezelwa ngcono kwengxolo kwi-spectum ebanzi. Le ndlela ivumela ukuphuculwa kwentsebenzo yokucoca ngaphezulu koluhlu olubanzi lweendlela ezibanzi zendabuko.
