Kedu ka Supercapacitors si enweta nha nha voltaji

Modul supercapacitorỌtụtụ mgbe na-eche nsogbu nke adịghị mma voltaji n'etiti sel.Ihe a na-akpọ supercapacitor modul bụ modul nke nwere ọtụtụ supercapacitors;n'ihi na paramita nke supercapacitor siri ike na-kpamkpam na-agbanwe agbanwe, voltaji ahaghị nhata na-adịkarị mfe ime, na ụfọdụ supercapacitors nwere ike na-enweta overvoltage, nke kpọrọ ihe na-emetụta mmepụta àgwà na ndụ nke supercapacitor, na ọbụna na-eduga ná ọdịda.

N'ime usoro ngwa supercapacitor, nguzozi voltaji dị mkpa.A na-ekewa teknụzụ nguzozi voltaji dị ugbu a ụzọ abụọ: nguzozi na-agafe agafe na nhazi ọrụ.

Ntụle na-agafe agafe

Ndozi n'ụzọ na-agafe agafe bụ iji resistors na semiconductor switches ma ọ bụ diodes iji dozie voltaji, na ịrụ ọrụ nke nchebe overvoltage site na iri oke ike nke supercapacitor voltaji.Ndị a na-ahụkarị gụnyere itule ntule resistor, mgba ọkụ resistor itule, na voltaji regulator tube itule.
N'ebe a, anyị na-ekwukarị banyere nguzozi voltaji resistor kacha dị mfe (njirimara ike adịghị mma):

Req bụ resistor na-edozi ahụ, nke jikọtara ya na sel supercapacitor.N'oge usoro nchaji nke modul ahụ, cell na-agbapụkwa site na Req, na cell nwere nnukwu voltaji na-agbapụta ngwa ngwa, si otú a na-arụ ọrụ nke ịhazi nchedo.N'ebe a, dị ka usoro nchaji dị iche iche si dị (ịchaji voltaji na-akwụ ụgwọ na chaja mgbe niile, nke abụọ nwere ike iji ya mee ihe n'ụzọ zuru ezu na ngwa bara uru), e nwekwara ọdịiche dị na njirisi maka ịhọrọ Req.

Ịchaji voltaji mgbe niile
Na-eche na voltaji chaja bụ U, ebe ọ bụ na voltaji nke supercapacitor modul na steeti kwụsiri ike na-ekesa n'ụzọ bụ isi dị ka EPR (obere sekit na-emeghe mgbe agbachara C zuru oke, yana ESR dị obere), mgbe agbakwunyere Req, ọ nwere ike. Aghọtara n'ezie dị ka dochie EPR na Req, yabụ Req ga-ahọrọ ndị na-emegide ya na nguzogide nha anya yana pere mpe karịa EPR, ka njikọ yiri ya wee rụọ ọrụ na-eduga (n'ozuzu 0.01 ~ 0.1EPR).Voltaji nke supercapacitor na steeti kwụ ọtọ bụ ReqU/(nReq).

Nchaji na-adị ugbu a
Na-eche na chaja ugbu a bụ I, sel supercapacitor ọ bụla na Req na-etolite akaghị iche.Mgbe voltaji nke cell capacitor na-ebili, ihe dị ugbu a na-agafe na cell capacitor na-adaba, na ugbu a na-agafe na Req na-abawanye.Mgbe capacitor na-akwụ ụgwọ n'ụzọ zuru ezu, ugbu a nke capacitor bụ 0, na cell voltaji nke capacitor bụ ReqI, ya bụ, mgbe cell voltaji nke niile usoro capacitors ruru ReqI, itule na-agwụ agwụ.Ya mere, uru nke resistor itule bụ Req=U(rated)/I.

Nhazi na-arụ ọrụ

Ndozi ọrụ na-arụ ọrụ bụ ịnyefe ike nke cell voltaji dị elu ma ọ bụ modul dum gaa na sel ndị ọzọ ruo mgbe voltaji nke sel niile kwụziri.N'ozuzu, ọnwụ dị ntakịrị, ma imewe ga-adị mgbagwoju anya karị.Ndị a na-ahụkarị bụ ihe ngbanwe DC/DC, ibe njikwa super capacitor pụrụ iche, wdg.
