Amakuru

Akayunguruzo kadakora, izwi kandi nka LC filter, ni urusobe rw'urufunguzo rugizwe n'uburyo bwo gukurura, ubushobozi bwo gukurura no kwirinda, rushobora gukurura harmoniki imwe cyangwa nyinshi. Imiterere y'urufunguzo rudakoreshejwe kandi rworoshye gukoresha ni uguhuza uburyo bwo gukurura n'ubushobozi bwo gukurura mu buryo bukurikiranye, bushobora gukora inzira yo gukurura impedance nke kuri harmoniki nkuru (3, 5 na 7); urufunguzo rumwe rudakoreshejwe, urufunguzo rudakoreshejwe kabiri na filter yo hejuru byose ni filter zo mu buryo bwo gukurura.
inyungu
Akayunguruzo kadakoreshejwe gafite ibyiza byo kuba imiterere yoroshye, igiciro gito, imikorere yizewe cyane ndetse n'igiciro gito cyo gukora. Karacyakoreshwa cyane nk'uburyo bwo kugenzura buhuza.
gushyira mu byiciro
Ibiranga icyuma gishyushya LC bigomba kuzuza ibisabwa bya tekiniki byagenwe. Ibi bisabwa tekiniki akenshi ni ugukora kugabanya imikorere mu gice cy'amajwi, cyangwa mu gipimo cy'impinduka, cyangwa byombi; Hari igihe, ibisabwa mu gusubiza igihe mu gice cy'amajwi biratangwa. Ibyuma bidafite imbaraga bishobora kugabanywamo ibyiciro bibiri: ibyuma bishyushya ibyuma n'ibyuma bishyushya ibyuma binini. Muri icyo gihe, hakurikijwe uburyo butandukanye bwo gushushanya, bishobora kugabanywamo ibyuma bishyushya ibyuma by'ishusho n'ibyuma bishyushya ibyuma bikoresha ikoranabuhanga.
Akayunguruzo ko gutunganya
Akayunguruzo ko gutunganya karimo akayunguruzo kamwe ko gutunganya n'akayunguruzo ko gutunganya kabiri, gashobora kuyungurura akayunguruzo kamwe (ko gutunganya kamwe) cyangwa tubiri (ko gutunganya kabiri). Inshuro ya kayunguruzo ko gutunganya yitwa inshuro ya kayunguruzo ko gutunganya.
Akayunguruzo k'inzira nyinshi
Akayunguruzo k’impinduka nyinshi, kazwi kandi nka akayunguruzo ko kugabanya amplitude, ahanini karimo akayunguruzo k’impinduka nini ka mbere, akayunguruzo k’impinduka nini ka kabiri, akayunguruzo k’impinduka nini ka gatatu na akayunguruzo k’ubwoko bwa C, bikoreshwa mu kugabanya cyane harmonics iri munsi y’umuvuduko runaka, ari byo byitwa umuvuduko wo gukata akayunguruzo k’impinduka nyinshi.
Akayunguruzo k'ibipimo by'ishusho
Akayunguruzo kakozwe kandi gashyirwa mu bikorwa hashingiwe ku nyigisho y’ibipimo by’ishusho. Akayunguruzo kagizwe n’ibice byinshi by’ibanze (cyangwa ibice kimwe cya kabiri) bikozwe hakurikijwe ihame ry’impinduka zingana z’ishusho ku ihuza. Igice cy’ibanze gishobora kugabanywamo ubwoko bwa K buhamye n’ubwoko bwa m bukomoka kuri imiterere y’urusobe rw’amajwi. Dufashe urugero rwa akayunguruzo ka LC gafite impushya zo guhagarika igice cy’ibanze cya K gihamye kigenda cyiyongera mu buryo bumwe uko inshuro ziyongera; Akayunguruzo k’ibanze kagizwe na m gafite impushya zo guhagarika ku mpushya runaka mu gice cy’ibanze, kandi aho impushya zo guhagarika ziherereye hagenzurwa n’agaciro ka m mu gice cy’ibanze cyavuye kuri m. Ku kayunguruzo k’ibanze kagizwe n’ibice by’ibanze bya Cascaded Low-Pass, impushya zo guhagarika zihwanye n’igiteranyo cy’impushya zo guhagarika buri gice cy’ibanze. Iyo impedance y'imbere n'impedance y'umutwaro by'amashanyarazi bihagaritswe ku mpera zombi z'akayunguruzo bingana n'impedance y'ishusho ku mpera zombi, igabanuka ry'imikorere n'ihinduka ry'icyiciro bya kayunguruzo bingana n'igabanuka ry'imiterere yabyo n'ihinduka ry'icyiciro. (a) Akayunguruzo kagaragajwe kagizwe n'igice cya K gihoraho n'ibice bibiri bya m bikomoka kuri kajugujugu. Z π na Z π m ni impedance y'ishusho. (b) Ni ibihe bipimo byayo byo kugabanya. Aho imisozi ibiri ya attenuation /f ∞ 1 na f ∞ 2 muri stopband bigenwa n'agaciro ka m k'imirongo ibiri ya m ikomoka kuri.
Mu buryo nk'ubwo, ibyuma bipima umuvuduko mwinshi, ibyuma bipima umuvuduko n'ibyuma bipima umuvuduko bishobora no kuba bigizwe n'ibice by'ibanze bihuye.
Impedance y'ishusho y'akayunguruzo ntishobora kungana n'ubudahangarwa bw'imbere bw'amashanyarazi n'impedance y'umutwaro mu gice cyose cy'umuvuduko (itandukaniro ni rinini mu gice cyo guhagarara), kandi uburyo bwo kugabanya no kugabanya imikorere biratandukanye cyane mu gice cyo guhagarara. Kugira ngo ibimenyetso bya tekiniki bigerweho, ubusanzwe ni ngombwa kubika ingano ihagije y'uburyo bwo kugabanya no kongera ubugari bw'igice cyo guhagarara mu gishushanyo.
Akayunguruzo k'ibipimo by'imikorere
Iyi filter ntabwo igizwe n'ibice by'ibanze bya cascaded, ahubwo ikoresha imikorere ya network ishobora gukorwa hakoreshejwe R, l, C n'ibintu bya mutuelle kugira ngo igereranye neza imiterere ya tekiniki ya filter, hanyuma igakora circuit ya filter ijyanye nayo binyuze mu mikorere ya network. Dukurikije ibipimo bitandukanye byo gupima, imikorere itandukanye ya network irashobora kuboneka, kandi ubwoko butandukanye bwa filter burashobora kuboneka. (a) Ni imiterere ya filter yo hasi ikorwa hakoreshejwe ikigereranyo cya flattest amplitude (bertowitz approximation); Passband ni frequency irambuye cyane hafi ya zeru, kandi attenuation yiyongera kimwe iyo yegereye stopband. (c) Ni imiterere ya filter yo hasi ikorwa hakoreshejwe ikigereranyo cya ripple (Chebyshev approximation); Attenuation muri passband ihinduka hagati ya zeru na limite yo hejuru, kandi yiyongera kimwe muri stopband. (e) Ikoresha elliptic function approximation kugira ngo imenye imiterere ya filter yo hasi, kandi attenuation igaragaza impinduka za voltage zihoraho haba muri passband na stopband. (g) Ni ikiranga akayunguruzo k’inzira ntoya kagaragara binyuze mu; Kugabanuka kw’inyuguti mu gice cy’inzira bihinduka mu buryo bungana, kandi kugabanuka kw’inyuguti mu gice cyo guhagarika bihinduka bitewe n’izamuka n’igabanuka bisabwa n’ikimenyetso. (b) , (d), (f) na (H) ni imiyoboro ijyanye n’izi kayunguruzo k’inzira ntoya.
Uduce duto two gupima hejuru, gupima umuvuduko w'amajwi n'uduce duto dukoreshwa mu gupima umuvuduko w'amajwi akenshi dukomoka ku duce duto dukoresha umuvuduko w'amajwi binyuze mu guhindura inshuro.
Akayunguruzo k'ibipimo bikora kakozwe hakoreshejwe uburyo bwo guhuza neza hakurikijwe ibisabwa n'ibipimo bya tekiniki, kandi gashobora kubona urujya n'uruza rufite imikorere myiza kandi ruhendutse,
Akayunguruzo ka LC biroroshye gukora, gahendutse, kanini mu murongo w'ingufu, kandi gakoreshwa cyane mu itumanaho, mu bikoresho no mu bindi bice; Muri icyo gihe, gakunze gukoreshwa nk'icyitegererezo cy'ubundi bwoko bwinshi bwa kayunguruzo.

Dushobora kandi guhindura ibice bya rf passive hakurikijwe ibyo ukeneye. Ushobora kwinjira ku ipaji yo guhindura kugira ngo utange ibisobanuro ukeneye.
