Họrọ inductor kwesịrị ekwesị maka ịgbanye ọkụ ọkụ | DỊKWA MMA

Ihe inductor , nke a makwaara dị ka nkpagbu, bụ "oke inertia" nke ugbu a na-agafe na ya. N'ikwu ya n'ụzọ ọzọ, n'ihi na-aga n'ihu nke mgbanwe ahụ, ihe dị ugbu a na inductor ga-anọgide na-aga n'ihu, ma ọ bụghị ya, ọ ga-emepụta nnukwu ọkụ ọkụ. Inductor bụ akụrụngwa magnetik, yabụ na ọ nwere nsogbu nke saturation magnetik. Ngwa ụfọdụ na-enye ohere inductance saturation, ụfọdụ ngwa na-ekwe ka ndị na-arụpụta ihe banye saturation site na ụfọdụ uru dị ugbu a, na ụfọdụ ngwa anaghị ekwe ka inductors jupụta, nke chọrọ ọdịiche dị na sekit pụrụ iche.

N'ọtụtụ ọnọdụ, inductor na-arụ ọrụ na "mpaghara linear", ebe inductance bụ ihe na-adịgide adịgide ma ọ dịghị agbanwe agbanwe na njedebe njedebe na ugbu a. Otú ọ dị, e nwere nsogbu a na-apụghị ileghara anya, ya bụ, winding nke inductor ga-eduga abụọ na-ekesa parameters (ma ọ bụ parasitic parameters), otu bụ-apụghị izere ezere winding iguzogide, ndị ọzọ bụ ekesa kpafuo capacitance metụtara winding. usoro na ihe.

Capacitance kpafuo nwere obere mmetụta na obere oge, mana ọ na-eji nwayọ na-apụta na mmụba nke ugboro ole. Mgbe ugboro ole karịrị otu uru, inductor nwere ike ịghọ njirimara capacitive. Ọ bụrụ na capacitance kpafuru akpafu bụ "na-etinye uche" n'ime capacitor, njirimara capacitance mgbe ụfọdụ ugboro nwere ike ịhụ site na sekit kwekọrọ na inductor.

Ọnọdụ ọrụ nke inductor na sekit

Dị nnọọ ka capacitor nwere chaja na mwepu ugbu a, inductor nwekwara ụgwọ na mwepu voltaji usoro. Voltage dị na capacitor dị nhata na ntinye nke ugbu a, na nke ugbu a na inductor na-adabere na ntinye nke voltaji. Ọ bụrụhaala na voltaji inductor na-agbanwe, ọnụego mgbanwe di / dt ugbu a ga-agbanwekwa; voltaji na-aga n'ihu na-eme ka ịrị elu dị ugbu a dị n'ahịrị, na ntụgharị voltaji na-eme ka nke ugbu a na-ebelata.

Ọ dị ezigbo mkpa ịgbakọ inductance ziri ezi iji họrọ inductor kwesịrị ekwesị na capacitor mmepụta iji nweta obere mpụta voltaji ripple.

Nhọrọ inductance nke mgbanaka ọkụ ọkụ

Mgbe ị na-ahọpụta ndị inductor maka inyefe ọkụ na-agbanwe ego, ọ dị mkpa iji chọpụta oke ntinye voltaji, voltaji mmepụta, ike mgbanwe ugboro, kacha ripple ugbu a na ọrụ okirikiri.

Nhọrọ inductance nke nkwalite ngbanwe ọkụ ọkụ

N'ihi na inductance ngụkọta oge nke mbo mbuli ịmafe ike ọkọnọ, ma e wezụga na mmekọrịta dị n'etiti ọrụ okirikiri na inductance voltaji agbanweela, ndị ọzọ usoro bụ otu ihe ahụ dị ka nzọụkwụ-ala ịmafe ike ọkọnọ.

Biko mara na n'adịghị ka ike ọkọnọ nke buck, ibu ugbu a nke nkwalite ike na-enye ọ bụghị mgbe niile site na inductor ugbu a. Mgbe tube ngbanwe ahụ na-agbanye, onye na-emepụta ihe na-abanye n'ime ala site na tube mgba ọkụ, na ibu nke ugbu a na-enye site na mmepụta capacitor, ya mere capacitor mmepụta ga-enwerịrị ikike nchekwa ike zuru oke iji nye ugbu a chọrọ site na ibu. n'oge a. Otú ọ dị, n'oge nkwụsị nke ngbanwe ahụ, ugbu a na-agafe na inductor ọ bụghị nanị na-enye ibu ahụ, kamakwa ọ na-ebubo capacitor mmepụta.

N'ikwu okwu n'ozuzu, mgbe uru inductance na-ebuwanye ibu, ripple nke mmepụta ga-adị ntakịrị, ma nzaghachi ike nke ọkụ eletrik ga-adịkwa njọ, n'ihi ya, nhọrọ nke inductance uru nwere ike gbanwee dị ka ngwa ngwa chọrọ nke sekit iji nweta. mmetụta kacha mma.
