Transformer ni igikoresho gikoresha ihame rya electromagnetic induction kugirango ihindure voltage ya AC.Ibice byingenzi byingenzi birimo coil primaire, coil ya kabiri hamwe nicyuma.
Mu mwuga wa elegitoroniki, urashobora kubona kenshi igicucu cya transformateur, ibisanzwe bikoreshwa mugutanga amashanyarazi nka voltage ihinduka, kwigunga.
Muri make, igipimo cya voltage ya coil primaire na secondaire ihwanye nikigereranyo cyo guhinduranya ibice byambere na kabiri.Kubwibyo, niba ushaka gusohora voltage zitandukanye, urashobora guhindura igipimo cyibipimo bya coil.
Ukurikije inshuro zitandukanye zakazi za transformateur, zirashobora kugabanwa mubice bihindura imirongo mike hamwe na transfert nyinshi.Kurugero, mubuzima bwa buri munsi, inshuro yumurongo wumurongo uhinduranya ni 50Hz.Twise transformateur ikora kuriyi franse nkeya-ya transfert;Imikorere yumurongo wa transfert nyinshi irashobora kugera kuri kHz mirongo kugeza kuri magana kHz.
Ingano ya transfert yumurongo mwinshi ni nto cyane kuruta iy'umuvuduko muke uhinduranya hamwe nimbaraga zimwe zisohoka
Transformator nikintu kinini ugereranije mumashanyarazi.Niba ushaka gukora amajwi mato mugihe wemeza imbaraga zisohoka, ugomba gukoresha transformateur yumurongo mwinshi.Kubwibyo, impinduka nyinshi zikoreshwa muguhindura ibikoresho.
Ihame ryakazi rya transfert yumurongo mwinshi hamwe na transformateur yumurongo muto nimwe, byombi bishingiye kumahame yo kwinjiza amashanyarazi.Ariko, kubijyanye nibikoresho, "cores" zabo zikoresha ibikoresho bitandukanye.
Icyuma cyuma cya transfert yumurongo muke usanzwe ushyizwemo impapuro nyinshi zicyuma cya silicon, mugihe icyuma cyuma gihinduranya ibintu byinshi kigizwe nibikoresho bya magneti menshi (nka ferrite)..
Muri DC itajegajega yumuriro w'amashanyarazi, insimburangingo nkeya itanga ibimenyetso bya sine.
Muguhindura amashanyarazi yumuzunguruko, transfert yumurongo mwinshi wohereza ibimenyetso byumuvuduko mwinshi wa pulse kare.
Ku mbaraga zagenwe, ikigereranyo kiri hagati yimbaraga zisohoka nimbaraga zinjiza za transformateur bita imikorere ya transformateur.Iyo imbaraga zisohoka za transformateur zingana nimbaraga zo kwinjiza, imikorere ni 100%.Mubyukuri, transformateur nkiyi ntikibaho, kuberako gutakaza umuringa no gutakaza ibyuma bibaho, transformateur izagira igihombo runaka.
Gutakaza umuringa ni iki?
Kuberako impinduramatwara ihinduranya ifite imbaraga zo kurwanya, mugihe umuyaga unyuze muri coil, igice cyingufu kizahinduka ubushyuhe.Kuberako coil ya transformateur yakomerekejwe numuringa wumuringa, iki gihombo nanone cyitwa gutakaza umuringa.
Gutakaza icyuma ni iki?
Gutakaza ibyuma bya transformateur bikubiyemo ahanini ibintu bibiri: gutakaza hystereze no gutakaza eddy;Gutakaza Hystereze bivuga ko mugihe guhinduranya imbaraga zinyuze muri coil, hazavamo imirongo ya magneti yingufu kugirango inyure mucyuma, kandi molekile ziri imbere yicyuma zizunguruka hagati kugirango zitange ubushyuhe, bityo bitwara igice cyingufu zamashanyarazi;Kuberako umurongo wa rukuruzi wimbaraga unyura mubyuma, intoki yicyuma nayo izabyara amashanyarazi.Kuberako umuyaga urimo uzunguruka, nanone witwa eddy current, kandi igihombo cya eddy nacyo kizatwara ingufu z'amashanyarazi.
