Indwara ya Choke

DC irwanya AC nuburyo bworoshye bwo kuvuga, irashobora gutandukanya no kugabanya ibimenyetso bya AC, cyangwa gukora umuziki wa resonant hamwe na rezistor na capacitor, guhindura imvugo no guhitamo inshuro. Induction coil hamwe na capacitori murwego rushobora gukora LC tuning circuit. Nukuvuga ko, niba inshuro zinyeganyega zisanzwe 0 zumuzunguruko zingana ninshuro yikimenyetso kitari AC, reaction ya inductive na capacitif reaction yumuzunguruko nayo irangana, bityo ingufu za electromagnetique zinyeganyega imbere na inductor. , aribwo resonance phenomenon yumuzingi wa LC. Iyo resonant, reaction ya inductive hamwe na capacitif reaction yumuzunguruko bingana kandi bigahinduka, bityo reaction ya inductive yumuriro wose wumuzunguruko ni nto, kandi umubare uriho (bivuga - 0 AC signal), bityo LC resonant umuzenguruko ufite umurimo wo guhitamo inshuro, kandi urashobora guhitamo ibimenyetso bya AC yumurongo runaka.

Iyo ibimenyetso byerekana inshuro nyinshi, biroroshye koherezwa. Nyamara, imirongo rusange yikimenyetso ntigira urwego rukingira. Imirongo yikimenyetso ihinduka antenne nziza cyane kugirango yakire ubwoko bwubwoko bwose bwumuvuduko mwinshi-mwinshi mubidukikije. Niba ibyo bimenyetso byashyizwe hejuru kubimenyetso byambere byandujwe, birashobora no guhindura ibimenyetso byambere byanduye byanduye kandi bikabangamira cyane imikorere isanzwe yibikoresho bya elegitoroniki, Kubwibyo, birakenewe kugabanya interineti ya electronique (EM) yibikoresho bya elegitoroniki. Munsi yimikorere yimpeta ya magneti, nubwo ibimenyetso bisanzwe kandi byingirakamaro bigenda neza, birashobora guhagarika ibimenyetso byihuta byihuta cyane, kandi igiciro ni gito. Igikoresho cya magnetiki inkingi nayo igira uruhare runini hejuru y urusaku, ibimenyetso byerekana, guhagarika imiyoboro no guhagarika imiyoboro ya electromagnetic.
