Ku bijyanye na inductor, abashushanya benshi bafite ubwoba kuko batazi gukoreshainductor.Inshuro nyinshi, kimwe ninjangwe ya Schrodinger: gusa iyo ufunguye agasanduku, ushobora kumenya niba injangwe yapfuye cyangwa itapfuye.Gusa iyo inductor yagurishijwe kandi igakoreshwa mukuzunguruka dushobora kumenya niba ikoreshwa neza cyangwa idakoreshwa.

Kuki inductor igoye cyane?Kuberako inductance ikubiyemo umurima wa electromagnetique, hamwe nigitekerezo kijyanye numurima wa electromagnetique hamwe no guhinduka hagati ya magnetiki nu mashanyarazi akenshi biragoye kubyumva.Ntabwo tuzaganira ku ihame rya inductance, amategeko ya Lenz, amategeko yukuboko kwi buryo, nibindi. Mubyukuri, kubijyanye na inductor, icyo twakagombye kwitondera kiracyari ibipimo fatizo bya inductor: agaciro ka inductance, igipimo cyagenwe, inshuro zumvikana, inshuro nziza (Q agaciro).

Tuvuze agaciro ka inductance, biroroshye ko buriwese yumva ko ikintu cya mbere twitaho ari "agaciro ka inductance".Icyangombwa nugusobanukirwa icyo agaciro ka inductance kagereranya.Agaciro ka inductance kagereranya iki?Agaciro ka inductance yerekana ko uko agaciro kangana, imbaraga nyinshi inductance ishobora kubika.

Noneho dukeneye gutekereza ku ruhare runini cyangwa ruto rwinduction hamwe nimbaraga nyinshi cyangwa nkeya zibika.Iyo agaciro ka inductance kagomba kuba nini, kandi mugihe agaciro ka inductance kagomba kuba nto.

Muri icyo gihe, nyuma yo gusobanukirwa nigitekerezo cyagaciro ka inductance no guhuza hamwe na formulaire ya theoretical of inductance, dushobora kumva icyagira ingaruka ku gaciro ka inductance mu gukora inductor nuburyo bwo kongera cyangwa kugabanya.

Umuyoboro wagenwe nawo uroroshye cyane, kimwe nuburwanya, kuko inductor ihujwe murukurikirane rwumuzunguruko, byanze bikunze izatemba.Agaciro kemewe nigiciro cyagenwe.

Imirongo yumvikana ntabwo byoroshye kubyumva.Inductor ikoreshwa mubikorwa ntigomba kuba ikintu cyiza.Bizaba bifite ubushobozi bungana, birwanya bihwanye nibindi bipimo.

Umuyoboro wa rezonant bisobanura ko munsi yiyi frequency, ibiranga umubiri wa inductor biracyitwara nka inductor, kandi hejuru yiyi frequency, ntibikigikora nka inductor.

Ikintu cyiza (Q agaciro) kirarenze urujijo.Mubyukuri, ibintu bifite ireme bivuga ikigereranyo cyingufu zibitswe na inductor hamwe nigihombo cyatewe na inductor mugihe cyikimenyetso kuri radiyo runaka.

Twabibutsa ko ikintu cyiza kiboneka kumurongo runaka.Iyo rero tuvuze ko Q agaciro ka inductor ari hejuru, mubyukuri bivuze ko iruta Q agaciro kayandi mashanyarazi kumurongo runaka cyangwa umurongo runaka.

Sobanukirwa n'ibi bitekerezo hanyuma ubizane mubikorwa.

Inductors muri rusange zigabanyijemo ibyiciro bitatu mubisabwa: inductors power, inductors-frequency-inductor zisanzwe.

Ubwa mbere, reka tuganireamashanyarazi.
Imashanyarazi ikoreshwa mumashanyarazi.Mu byongeramo ingufu, ikintu cyingenzi ugomba kwitondera ni agaciro ka inductance hamwe nigiciro cyagenwe.Inshuro ya resonance nibintu byiza mubisanzwe ntibigomba guhangayikishwa cyane.

Kubera iki? KuberaamashanyaraziBikunze gukoreshwa mubihe bike-byinshyi.Wibuke ko ni ubuhe buryo bwo guhinduranya imbaraga za module mumashanyarazi azunguruka cyangwa umuzunguruko?Nibihumbi magana K gusa, kandi byihuta byihuta byihuta ni bike M. Mubisanzwe tuvuze, agaciro kari hasi cyane ugereranije na re-resonant inshuro ya inductor yingufu.Ntabwo rero dukeneye kwita kubijyanye na resonant frequency.

Mu buryo busa nabwo, muguhindura amashanyarazi, ibisohoka byanyuma ni DC ya none, naho AC igizwe mubyukuri kubice bike.

Kurugero, kuri 1W BUCK yamashanyarazi, ibice bya DC bingana na 85%, 0.85W, naho AC igizwe na 15%, 0.15W.Dufate ko ikintu cyiza Q cyingufu zikoreshwa ari 10, kuko ukurikije ibisobanuro byikintu cyiza cya inductor, ni igipimo cyingufu zibitswe na inductor ningufu zikoreshwa na inductor.Inductance ikeneye kubika ingufu, ariko ibice bya DC ntibishobora gukora.Gusa ibice bigize AC birashobora gukora.Noneho igihombo cya AC cyatewe niyi inductor ni 0.015W gusa, bingana na 1.5% yingufu zose.Kuberako Q agaciro ka inductor yimbaraga nini cyane kurenza 10, mubisanzwe ntabwo twita cyane kuri iki kimenyetso.

Reka tuganireinductor yumurongo mwinshi.
Induction nyinshi-zikoreshwa cyane mukuzunguruka kwinshi.Mumuzunguruko mwinshi, ibisanzwe mubisanzwe ni bito, ariko inshuro zisabwa ni nyinshi cyane.Kubwibyo, ibyingenzi byingenzi byerekana inductor bihinduka resonance inshuro nyinshi nibintu byiza.

Imirongo yumvikana hamwe nibintu byiza biranga bifitanye isano cyane ninshuro, kandi harigihe hariho umurongo uranga umurongo uhuye nabo.

Iyi mibare igomba kumvikana.Ugomba kumenya ko ingingo yo hasi mubishushanyo mbonera bya resonance yumurongo uranga ni rezanse yumurongo.Indangagaciro yibintu ijyanye numurongo utandukanye uzaboneka mugishushanyo kiranga igishushanyo cyibintu byiza.Reba niba ishobora guhuza ibikenewe bya porogaramu yawe.

Kuri inductors zisanzwe, dukwiye kureba cyane cyane muburyo butandukanye bwo gusaba, bwaba bukoreshwa mumashanyarazi ya filteri yumuzunguruko cyangwa mukayunguruzo kerekana ibimenyetso, umubare wibimenyetso bingana, uko bigenda, nibindi.Kubintu bitandukanye, dukwiye kwitondera imiterere yabo itandukanye.

Niba ubishaka, nyamuneka nyamuneka hamagaraMingdakubindi bisobanuro.
