Iterambere ryiterambere rya voltage yumurongo mwinshi isoko

Hamwe niterambere ryihuse ryikoranabuhanga rigezweho rya tekinoroji na tekinoroji yo kugenzura mudasobwa, impinduramatwara yikoranabuhanga ya moteri yamashanyarazi yaratejwe imbere.Igenzura ryihuta aho kugenzura umuvuduko wa DC, kugenzura ibyuma bya mudasobwa aho kugenzura ibigereranyo byahindutse inzira yiterambere.Ac moteri yumurongo uhindura umuvuduko nuburyo bukomeye bwo kuzigama ingufu, kunoza umusaruro, kuzamura ubwiza bwibicuruzwa, no kuzamura ibidukikije.Guhindura umuvuduko wihutahamwe nubushobozi bwayo buhanitse, imbaraga zikomeye, kimwe nuburyo bwiza bwo kugenzura umuvuduko no gukora feri nibindi byiza byinshi bifatwa nkigenzura ryihuta cyane.

Icyambereinverter yo hejuru, igizwe na rectriste ya thyristor, inverter ya thyristor nibindi bikoresho, ifite inenge nyinshi, ihuza ryinshi, kandi igira ingaruka kumashanyarazi na moteri.Mu myaka yashize, hari ibikoresho bishya byateguwe bizahindura iki kibazo, nka IGBT, IGCT, SGCT nibindi.Inverteri nini ya voltage igizwe nayo ifite imikorere myiza kandi irashobora kumenya PWM inverter ndetse no gukosora PWM.Ntabwo guhuza gusa ari bito, ariko nanone imbaraga zateye imbere cyane

Ikoreshwa rya Ac frequency ihinduranya ryihuta ryikoranabuhanga ni ihuriro ryamashanyarazi akomeye kandi adakomeye, tekinoroji yubukanishi n’amashanyarazi, ntabwo ari ugukemura gusa ihinduka ryimbaraga nini (gukosora, inverter), ariko kandi no gukemura ikusanyamakuru, guhinduka no kohereza , igomba rero kugabanywamo imbaraga no kugenzura ibice bibiri.Iyambere igomba gukemura ibibazo bya tekiniki bijyanye na voltage nini nu muyoboro mwinshi, naho iyanyuma igomba gukemura software hamwe nibibazo byo kugenzura ibyuma.Kubwibyo, ejo hazaza h’umuvuduko mwinshi wo guhinduranya umuvuduko woguhindura tekinoroji nabyo bizatezwa imbere muribi bice byombi, imikorere yingenzi ni:

(1)Umuvuduko mwinshi uhindagurikaIterambere mu cyerekezo cyimbaraga nyinshi, miniaturizasi nuburemere.

(2)muremurevoltage ihindagurikaItezimbere mubyerekezo bibiri: igikoresho cyerekezo cyumubyigano mwinshi hamwe na superposition nyinshi (urukurikirane rwibikoresho hamwe nuruhererekane rwibice).

:amashanyarazi menshi ahindagurika

(3) Kuri iki cyiciro, IGBT, IGCT, SGCT iracyafite uruhare runini, SCR, GTO izasohoka ku isoko rya inverter.

(5) Menya neza uburyo bwa digitale na automatike: tekinoroji yo kwishyiriraho;Gutunganya tekinoroji yo kwitezimbere;Ikoranabuhanga ryo kwisuzumisha.
