Ukugqitha
I-capacitor ye-bypass sisixhobo sokugcina amandla esinika amandla kwisixhobo sendawo, esilinganisa imveliso yomlawuli kunye nokunciphisa imfuno yomthwalo.Njengebhetri encinci ehlaziywayo, i-bypass capacitor inokuhlawulwa kwaye ikhutshwe kwisixhobo.Ukunciphisa i-impedance, i-bypass capacitor kufuneka ibekwe ngokusondeleyo kunokwenzeka kwipini yamandla okubonelela kunye nepini yomhlaba yesixhobo somthwalo.Le yindlela elungileyo yokuthintela ukuphakama okunokubakho emhlabeni kunye nengxolo ebangelwa ngamaxabiso agqithisayo egalelo.Amandla omhlaba kukuhla kwamandla ombane kumdibaniso womhlaba xa udlula kwi-burr yangoku ephezulu.
Ukuqhawula umtshato
Ukuqhawula umtshato, okwabizwa ngokuba kukuqhawula umtshato.Ngokubhekiselele kwisekethe, inokuhlala ihlukaniswa phakathi komthombo oqhutywayo kunye nomthwalo oqhutywayo.Ukuba i-capacitance yomthwalo inkulu kakhulu, isiphaluka sokuqhuba kufuneka sihlawule kwaye sikhuphe i-capacitor ukugqiba ukutsiba kwesignali, kwaye yangoku inkulu xa i-edge inyuka iphezulu, ukwenzela ukuba i-current eqhutywayo iya kuthabatha unikezelo lwangoku olukhulu, kwaye kwi-inductance kwisekethe, ukuchasana (ingakumbi i-inductance kwi-chip pin, eya kuvelisa i-bounce), le yangoku ngokwenene yingxolo ehambelana nemeko eqhelekileyo, eya kuchaphazela inqanaba langaphambili Le yinto ebizwa ngokuba " ukudibanisa”.
I-decoupling capacitor idlala indima "yebhetri", ukuhlangabezana notshintsho lwangoku lwesekethe ye-drive, ukuphepha ukuphazamiseka kokudibanisa.
Ukudibanisa i-bypass capacitor kunye ne-decoupling capacitor kuya kuba lula ukuyiqonda.I-bypass capacitor eneneni iyaqhawuka, kodwa i-bypass capacitor ngokubanzi ibhekisa kwi-bypass bypass ephezulu, oko kukuthi kuphuculwe indlela ephantsi yokukhupha i-impedance kwingxolo ephezulu yokutshintsha.I-high-frequency bypass capacitor incinci ngokubanzi, ngokwe-resonant frequency ithathwa ngokubanzi 0.1μF, 0.01μF, njl.;ngelixa umthamo we-decoupling capacitor ngokuqhelekileyo mkhulu, unokuba ngu-10μF okanye ukhulu, ngokweeparamitha zokusabalalisa kwisekethe, kunye nobukhulu benguqu kwi-drive yangoku ukumisela.I-Bypass kukucoca uphazamiseko kumqondiso wegalelo, ngelixa ukuqhawula kukucoca ngaphandle kokuphazamiseka kwisignali yemveliso ukuthintela isignali yokuphazamiseka ekubuyeleni kunikezelo lwamandla.Oku kufanele kube ngumahluko obalulekileyo phakathi kwabo.
Ukuhluza
Ngokwethiyori (oko kukuthi, ukucinga ukuba i-capacitor ihlambulukile), inkulu i-capacitance, i-impedance ephantsi kwaye iphezulu i-frequency ehamba ngayo.Kodwa ekusebenzeni, uninzi lwee-capacitors ezingaphezulu kwe-1μF zii-electrolytic capacitors, ezinecandelo elikhulu le-inductive, ngoko ke i-impedance iya kwanda endaweni emva kokuba i-frequency iphezulu.Ngamanye amaxesha unokubona i-capacitance enkulu ye-electrolytic capacitor ngokuhambelana ne-capacitor encinci, xa i-capacitor enkulu ngokusebenzisa i-frequency ephantsi, i-capacitor encinci ngokusebenzisa i-frequency ephezulu.Indima ye-capacitance kukudlula ukuchasana okuphezulu okuphantsi, ngokuxhathisa amaza omoya aphantsi.I-capacitance inkulu, kulula ukudlula i-frequency ephantsi.Ngokukhethekileyo isetyenziswe ekuhluzeni, i-capacitor enkulu (1000μF) isihluzi esisezantsi rhoqo, i-capacitor encinci (20pF) isihluzo esiphezulu.Abanye abasebenzisi baye bathelekisa i-capacitor yokucoca "kwichibi lamanzi".Ekubeni i-voltage kuzo zombini iziphelo ze-capacitor ayitshintshi ngequbuliso, kunokubonwa ukuba ukuphakama kwe-frequency yesignali, kokukhona ukuncipha okukhulu, okunokuthi kuchazwe ngokucacileyo ukuba i-capacitor ifana nechibi lamanzi, engabangelwa yi-attenuation. amathontsi ambalwa amanzi ukuze adibanise okanye enze umphunga utshintsho kumthamo wamanzi.Iguqula inguqu yombane ibe yinguquko yangoku, kwaye okukhona iphezulu ifrikhwensi, iphezulu iphezulu yangoku, ngaloo ndlela ibhufa amandla ombane.Ukucoca yinkqubo yokutshaja, ukukhupha.
Ukugcinwa kwamandla
I-capacitor yokugcina amandla iqokelela intlawulo nge-rectifier kwaye idlulisela amandla agciniweyo ngokusebenzisa umguquli okhokelela ekuphumeni kokunikezelwa kwamandla.I-Aluminium electrolytic capacitors ene-voltage ratings ye-40 ukuya kwi-450 VDC kunye nexabiso le-capacitance phakathi kwe-220 kunye ne-150,000 μF (efana ne-B43504 okanye i-B43505 esuka kwi-EPCOS) isetyenziswa ngokuqhelekileyo.Ngokuxhomekeke kwiimfuno zonikezelo lwamandla, izixhobo ngamanye amaxesha zixhunyiwe kwichungechunge, ngokuhambelana okanye ukudibanisa kwayo.Kubonelelo lwamandla olunomgangatho wamandla angaphezu kwe-10 kW, ii-capacitors ze-screw terminal ezimile njengetoti zidla ngokusetyenziswa.
