A bịa n'ihe gbasara inductor, ụjọ na-atụ ọtụtụ ndị na-emepụta ihe n'ihi na ha amaghị ka esi ejiinductor. Ọtụtụ oge, dị ka nwamba Schrodinger: naanị mgbe imepe igbe ahụ, ị ​​nwere ike ịma ma pusi anwụọla ma ọ bụ na ọ bụghị. Naanị mgbe a na-eresị inductor ma jiri ya mee ihe na sekit, anyị nwere ike ịma ma ejiri ya mee ihe nke ọma ma ọ bụ na ejighị ya.

Gịnị kpatara inductor ji esi ike? N'ihi na inductance na-agụnye oghere electromagnetic, na ozizi dị mkpa nke oghere electromagnetic na mgbanwe n'etiti oghere magnetik na eletrik na-abụkarị ihe siri ike nghọta. Anyị agaghị atụle ụkpụrụ nke inductance, iwu Lenz, iwu aka nri, wdg N'ezie, banyere inductor, ihe anyị kwesịrị ịṅa ntị ka bụ isi parameters nke inductor : inductance uru, gosiri ugbu a, resonant ugboro, àgwà ihe. (Q uru).

N'ikwu okwu banyere uru inductance, ọ dịịrị onye ọ bụla mfe ịghọta na ihe mbụ anyị na-elebara anya bụ "uru inductance" ya. Isi ihe bụ ịghọta ihe uru inductance na-anọchi anya ya. Kedu ihe uru inductance na-anọchi anya? Uru inductance na-anọchi anya na ka uru ahụ buru ibu, ka ike inductance nwere ike ịchekwa.

Mgbe ahụ, anyị kwesịrị ịtụle ọrụ nke nnukwu ma ọ bụ obere uru inductance na ike ọ na-echekwa ma ọ bụ karịa. Mgbe uru inductance kwesịrị ịdị ukwuu, na mgbe uru inductance kwesịrị ịdị obere.

N'otu oge ahụ, mgbe ịghọta echiche nke inductance uru na ijikọta na usoro iwu usoro nke inductance, anyị nwere ike ịghọta ihe na-emetụta uru nke inductance na n'ichepụta nke inductor na otú na-abawanye ma ọ bụ ibelata ya.

The gosiri ugbu a dịkwa nnọọ mfe, dị nnọọ ka ndị na-eguzogide, n'ihi na inductor ejikọrọ na usoro na sekit, ọ ga-apụghị izere ezere na-asọpụta ugbu a. Uru a na-anabata ugbu a bụ akara ugbu a.

ugboro resonant adịghị mfe nghọta. Inductor eji eme ihe agaghị abụ ezigbo akụrụngwa. Ọ ga-enwe ike nhata, nguzogide nhata na paramita ndị ọzọ.

Resonant ugboro pụtara na n'okpuru ugboro a, àgwà anụ ahụ nke inductor ka na-akpa àgwà dị ka onye inductor, na karịa nke a ugboro, ọ naghịzi eme ka onye inductor.

Ihe dị mma (Q uru) na-agbagwoju anya karị. N'ezie, àgwà ihe na-ezo aka n'ókè nke ike nke inductor na-echekwa na ike ọnwụ nke inductor kpatara na okirikiri mgbaàmà n'oge ụfọdụ ugboro ugboro.

Ekwesiri iburu n'uche ebe a na a na-enweta ihe omuma ihe n'otu oge. Ya mere, mgbe anyị na-ekwu na Q uru nke onye inductor dị elu, ọ pụtara n'ezie na ọ dị elu karịa Q uru nke ndị ọzọ inductor n'otu oge ugboro ma ọ bụ ụfọdụ ugboro band.

Ghọta echiche ndị a wee webata ha n'ọrụ.

A na-ekekarị ndị inductor ụzọ atọ n'ime ngwa: ike inductor, inductor dị elu na inductor nkịtị.

Nke mbụ, ka anyị kwuo banyere yaike inductor.
A na-eji ike inductor na sekit ike. N'etiti ndị inductor ike, ihe kachasị mkpa ị ga-aṅa ntị bụ uru inductance na ọnụ ahịa dị ugbu a. Ugboro resonance na ihe dị mma anaghị achọkarị inwe nchegbu.

Gịnị mere? N'ihi naike inductorsA na-ejikarị ya eme ihe na obere oge na ọnọdụ dị elu ugbu a. Cheta na ihe bụ mgbanwe ugboro nke ike modul na boost circuit ma ọ bụ buck circuit? Ọ bụ naanị narị ole na ole K, na ugboro ole na-agbanwe ngwa ngwa bụ naanị ole na ole M. N'ikwu okwu n'ozuzu, uru a dị ala karịa ugboro ole na-emegharị onwe ya nke ike inductor. Ya mere, anyị adịghị mkpa na-eche banyere resonant ugboro.

N'otu aka ahụ, na sekit ike ịgbanwee, mmepụta ikpeazụ bụ DC ugbu a, na akụkụ AC na-akwụ ụgwọ n'ezie maka obere akụkụ.

Dịka ọmụmaatụ, maka mmepụta ike 1W BUCK, akụkụ DC na-akwụ maka 85%, 0.85W, na akụkụ AC maka 15%, 0.15W. Ka e were ya na ihe dị mma Q nke ike inductor eji eme ihe bụ 10, n'ihi na dịka nkọwa nke ihe dị mma nke inductor si dị, ọ bụ oke ike nke inductor na-echekwa na ike nke inductor na-eri. Inductance kwesịrị ịchekwa ike, mana akụrụngwa DC enweghị ike ịrụ ọrụ. Naanị akụrụngwa AC nwere ike ịrụ ọrụ. Mgbe ahụ ọnwụ AC nke inductor a kpatara bụ naanị 0.015W, na-aza 1.5% nke ike niile. N'ihi na uru Q nke inductor ike dị ukwuu karịa 10, anyị anaghị echekarị banyere ihe ngosi a.

Ka anyị kwuo maka yaelu-ugboro inductor.
A na-eji ihe inductor dị elu na sekit dị elu. Na sekit ugboro ugboro dị elu, nke ugbu a na-adịkarị obere, mana ugboro ole achọrọ dị oke elu. Ya mere, ndị isi egosi nke inductor na-aghọ resonance ugboro na àgwà ihe.
