Akayunguruzo

Akayunguruzo gashobora kuyungurura neza inshuro runaka y’umuvuduko w’amashanyarazi cyangwa inshuro itari iyo frequency, kubona ikimenyetso cy’isoko ry’amashanyarazi cy’umuvuduko runaka, cyangwa gukuraho ikimenyetso cy’ingufu z’umuvuduko runaka.

 

Intangiriro

Akayunguruzo ni igikoresho cyo guhitamo cyemerera igice cyihariye cy’umuvuduko mu kimenyetso koherezwa, kandi ibindi bice by’umuvuduko biragabanuka cyane. Iki gikorwa cyo guhitamo hakoreshejwe akayunguruzo gishobora gukurwa mu rusaku rw’urusaku rw’urujijo cyangwa gukora isesengura rya spectrum. Mu yandi magambo, cyitwa akayunguruzo gashobora gutuma igice cyihariye cy’umuvuduko mu kimenyetso kinyura, kandi kagagabanya cyane cyangwa kagahagarika ibindi bice by’umuvuduko. Akayunguruzo ni igikoresho kiyungururwa n’umuvuduko. "Umuvuduko" ni igitekerezo cyagutse cyane, mu rwego rw’ikoranabuhanga rya elegitoroniki, "umuvuduko" ugarukira gato ku gikorwa cyo gukuramo agaciro k’ingano zitandukanye z’umubiri uko igihe kigenda. Igikorwa gihindurwamo igihe cy’umuvuduko cyangwa umuriro binyuze mu ngano zitandukanye z’umubiri, cyangwa ibimenyetso. Kubera ko igihe cyigenga ari agaciro gahoraho, kitwa ikimenyetso cy’igihe gihoraho, kandi mu buryo busanzwe cyitwa ikimenyetso cya analogue.

Gushungura ni igitekerezo cy'ingenzi mu gutunganya ibimenyetso, kandi akazi ko kuyungurura uruziga muri DC voltage regulator ni ukugabanya igice cya AC muri DC voltage uko bishoboka kose, kugumana DC ibigize, kugira ngo voltage ripple coefficient isohoka igabanuke, waveform ihinduke Smooth.

TIbipimo by'ingenzi:

Ingano yo hagati: Ingano f0 y'umurongo unyuraho w'urufunguzo, muri rusange fata f0 = (f1 + f2) / 2, f1, f2 nk'umurongo unyuraho w'urufunguzo cyangwa umurongo unyuraho w'urufunguzo ibumoso, iburyo bunyuranyije n'aho umurongo wa 1 dB cyangwa 3DB unyura. Umurongo unyuraho w'urufunguzo ukunze kubara umurongo unyuraho w'umurongo w'urufunguzo hamwe n'agace gato k'igihombo cyo kwinjiramo.

Itariki ntarengwa: Bivuga inzira igana ku nzira y'umurongo unyuraho wa filter yo hasi n'umurongo unyuraho wa filter yo hejuru. Ubusanzwe isobanurwa mu gice cyo gutakaza kingana na 1 dB cyangwa 3DB. Igihombo cyo kugereranya reference reference ni: pass yo hasi ishingiye ku ishyirwa rya DC, naho Qualcomm ishingiye ku nshuro ihagije yo gusohora hejuru ya parasite strip.

Umuyoboro wa Passband: yerekeza ku bugari bwa spectrum busabwa kugira ngo utambuke, BW = (F2-F1). F1, F2 ishingiye ku gutakaza k'injira kuri frequence yo hagati F0.

Igihombo cyo gushyiramo: Bitewe no kwinjiza akayunguruzo mu kirere cy'ikimenyetso cy'umwimerere mu muyoboro, igihombo kiri hagati cyangwa hagati, nk'uko bisabwa kugira ngo igihombo cyose gikomere.

Gucika: Bivuga ku rugero rwa bandwidth ya 1DB cyangwa 3DB (inshuro zo gukata), igihombo cyo gushyiramo gihindura urwego rw'inshuro ku murongo w'igihombo.

Ihindagurika ry'imbere: Gutakaza uburyo bwo gushyiramo umurongo unyuze mu murongo hamwe n'impinduka z'impinduka mu murongo unyuramo wa 1db ni 1db.

Guhagarara mu itsinda: Pima niba ikimenyetso kiri mu muyoboro w'inzira muri filter ari cyiza kugira ngo gihuze n'uburyo filter igenda. Ihuye neza VSWR = 1: 1, VSWR iruta 1 iyo idahuye. Ku muyoboro nyawo, umuyoboro w'itumanaho unyura kuri VSWR ni munsi ya 1.5: 1 muri rusange ni munsi ya BW3DB, ibi bikaba bitanga igipimo cya BW3DB n'uburyo filter igenda n'igihombo cyo kwinjira.

Gutakaza inzu: Umubare wa desibeli (DB) z'imbaraga z'ikimenyetso cya port n'imbaraga za reflection zingana na 20 Log 10ρ, ρ ni coefficient ya reflection ya voltage. Igihombo cyo kugaruka ntarengwa iyo imbaraga z'inyongera zinjijwe na port.

Gukora inyigo yo gukata umurongo: ikimenyetso cy'ingenzi cy'ubwiza bw'imikorere yo guhitamo icyuma gipima. Uko ikimenyetso cy'ingufu kirushaho kuba kinini, niko ikimenyetso cyo hanze gikomeza kugabanuka. Ubusanzwe hari ubwoko bubiri bw'ibitekerezo: uburyo bwo kugabanya ingano ya DB yo gukumira frequence ya fs, uburyo bwo kubara ni ukugabanuka kwa FS; ikindi kimenyetso cy'ibyifuzo byo gushyiramo icyuma gipima imiterere n'uburyo bwiza bwo gushyiramo icyuma gipima imiterere - coefficient ya rectangular (KXDB iruta 1), KXDB = BWXDB / BW3DB, (X ishobora kuba 40dB, 30dB, 20DB, nibindi). Uko icyuma gipima imiterere myinshi, niko icyuma gipima imiterere cyiyongera - ni ukuvuga ko agaciro ka 1 kaba kegereye, kandi ingorane zo gukora umusaruro ziba nini.

Gutinda: Ikimenyetso kivuga ku gihe gisabwa kugira ngo ikimenyetso cyohereze umurongo wa diagonal function, ni ukuvuga TD = DF / DV.

Imiterere y'icyiciro kiri mu itsinda: Iyi filter yerekana ibimenyetso ni uburyo ikimenyetso cyoherezwa mu buryo buhindagurika mu buryo butuma ibintu bihinduka. Iyi filter yakozwe n'imikorere ya linear phase response ifite umurongo mwiza w'uburyo ibintu bihinduka.

Icyiciro cy'ingenzi

Bigabanyijemo akayunguruzo ka analogi n'akayunguruzo ka digitale hakurikijwe ikimenyetso kirimo gutunganywa.

Uburyo bwo kunyuramo bwa filter idafite imbaraga bugabanyijemo low pass, high pass, bandpass, na all-pass filter.

Akayunguruzo k'amajwi make:yemerera ibice bifite umurongo muto cyangwa DC mu kimenyetso koherezwa, gukumira ibice bifite umurongo munini cyangwa kubangamira urusaku;

Akayunguruzo k'amajwi menshi: yemerera ibice bifite umurongo munini w’ingufu mu kimenyetso koherezwa, bikagabanya umurongo muto w’ingufu cyangwa ibice bya DC;

Akayunguruzo k'inyuguti z'umukandara: Bituma ibimenyetso byoherezwa, bihagarikwa ibimenyetso, bibangamira, kandi bigatera urusaku ruri munsi cyangwa hejuru y'umurongo;

Akayunguruzo gashobora gufatirwa: Ihagarika ibimenyetso biri mu murongo runaka w'amajwi, yemerera ibimenyetso bitari umurongo, bizwi kandi nka "notch filter".

Akayunguruzo k'amakarita yose: Akayunguruzo k’impinduka zose bivuze ko uburebure bw’ikimenyetso butazahinduka mu rugero rwose, ni ukuvuga ko ubwiyongere bw’uburebure bw’ikimenyetso cyose bungana na 1. Akayunguruzo rusange k’impinduka zose zikoreshwa mu cyiciro cy’icyiciro, ni ukuvuga urwego rw’impinduka z’ikimenyetso cy’injira, kandi icyiza ni uko ihinduka ry’icyiciro ringana n’umuvuduko, bingana na sisitemu yo gutinza igihe.

Ibice byombi bikoreshwa ni filters zitagira ingaruka (passive) n'izikora (active filters).

Bitewe n'aho akayunguruzo gaherereye, muri rusange kagabanijwemo akayunguruzo k'isahani n'akayunguruzo k'urukiramende.

Ku kibaho, shyira ku kibaho, nka PLB, JLB series filter. Ibyiza by'iki kiyunguruzo birahendutse, kandi ikibi ni uko filtering yihuta atari nziza. Impamvu nyamukuru ni:

1. Nta kwitandukanya hagati y’ibyinjira n’ibisohoka by’akayunguruzo, bishobora gutera kwihuza;

2, impedance yo gufunga ubutaka ya filter ntabwo iri hasi cyane, yagabanyije ingaruka zo kunyura ku murongo wa frequency nyinshi;

3, igice cy'isano hagati ya filter na chassis kizatera ingaruka mbi ebyiri: imwe ni ukwivanga kwa electromagnetic mu mwanya w'imbere wa chassis, ushyirwa kuri uyu murongo, ku mugozi, ugatanga filter hakoreshejwe imirasire ya cable. Kunanirwa; ikindi ni uko kwivanga hanze kuyungururwa na filter iri ku kibaho, cyangwa imirasire igakorerwa mu buryo butaziguye cyangwa butaziguye ku muyoboro uri ku kibaho, bigatera ibibazo byo kumva;

Udupapuro tw’urufunguzo, uduhurizo tw’urufunguzo n’utundi duhurizo tw’urufunguzo muri rusange dushyirwa ku gice cy’icyuma cya chassis yo kurinda. Kubera ko gishyirwa ku gice cy’icyuma, ubwinjiriro n’umusaruro by’urufunguzo biratandukanye rwose, ubutaka buba bufite ubutaka bwiza, kandi ingaruka ku nsinga zinyuzwa hejuru y’aho uruziga ruherereye, bityo ingaruka zo kuyungurura ni nziza cyane.

Akayunguruzo kadakora

Akayunguruzo ka passive ni akayunguruzo gakoresha resistor, reactor, na capacitor. Iyo frequency ya resonant, agaciro ka impedance ya circuit kaba gato, kandi impedance ya circuit ikaba nini, agaciro ka circuit gahindurwa ku frequency ya harmonic, kandi harmonic current gashobora gushungurwa; iyo frequence nyinshi za harmonic Akayunguruzo ko gutunganya kagizwe, hanyuma frequency ya harmonic ya feature ijyanye nayo ishobora gushungurwa, kandi kuyungurura umubare w’ingenzi wa harmonic (3, 5, 7) bigerwaho hakoreshejwe impedance ya impedance nto. Ihame nyamukuru ni ku mubare utandukanye wa harmonic, gushushanya frequency ya harmonic ni nto, kugera ku ngaruka zo gutandukanya kwa harmonic current, gutanga inzira ya bypass kuri harmonic nyinshi zabanje gushungurwa kugira ngo hagerwe ku bushobozi bwo gutunganya.

Filters zidafite imbaraga zishobora kugabanywamo filters zikoresha capacitive, power plant filter circuits, L-RC filter circuits, π-shaped RC filter circuits, multi-section RC filter circuits, na π-shaped LC filtering circuits. Kanda kugirango ukore muri single tuning filter, dual tuning filter, na high pass filter. Filters zidafite imbaraga zifite inyungu zikurikira: imiterere yazo ni yoroshye, ikiguzi cy'ishoramari ni gito, kandi igice gitanga ingufu muri sisitemu gishobora kwishyura ingufu muri sisitemu. Inoza ingufu za grid; imikorere ihamye ni myinshi, kubungabunga biroroshye, tekiniki igezweho, nibindi. Ikoreshwa cyane. Hari ibintu byinshi by'intege nke za filters zidafite imbaraga: ingaruka z'ibipimo bya grid power, agaciro ka impedance ya sisitemu n'umubare munini wa resonant frequencies akenshi zihinduka uko imikorere igenda; harmonic filter ni nto, umubare munini w'igihe cy'ingenzi ni wo gusa ushobora gushungurwa Harmonics, cyangwa bitewe n'ibisigazwa bihuriranye, kongera harmonics; guhuza hagati ya filtering na reactive compensation na pressure regulating; uko umuriro unyura muri filter, bishobora gutera imikorere y'ibikoresho byinshi; Ibikoresho bikoreshwa ni binini cyane, uburemere n'ingano ni binini; kudahindagurika mu mikorere ni bike. Kubwibyo, icyuma gikora gifite imikorere myiza ni cyo gikoreshwa cyane.

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