Umuhinduzi wa DC DC

Inyinshi mu mashini zihindura amashanyarazi za DC-DC zagenewe guhindura imiterere y’amashanyarazi mu buryo bumwe, kandi ingufu zishobora gutembera gusa kuva ku ruhande rw’injira kugera ku ruhande rw’isohoka. Ariko, imiterere y’imashini zose zihindura amashanyarazi zishobora guhinduka ku buryo bw’injira, bishobora gutuma ingufu zisubira inyuma kuva ku ruhande rw’isohoka kugera ku ruhande rw’injira. Uburyo ni uguhindura diode zose zikajya ku buryo bwigenga bwo gutunganya imikorere. Imashini ihindura imiterere y’amashanyarazi ishobora gukoreshwa mu binyabiziga n’ibindi bicuruzwa bisaba feri isubiramo. Iyo ikinyabiziga gikoze, imashini itanga ingufu ku mapine, ariko iyo ifata feri, amapine azatanga ingufu kuri iyo mashini ihindura imiterere y’amashanyarazi.

Guhinduranya umuyoboro biragoye cyane ukurikije ikoranabuhanga. Ariko, kubera ko imiyoboro myinshi ipfunyitse mu miyoboro ihuriweho, hakenewe ibice bike. Mu gushushanya imiyoboro, Kugira ngo ugabanye urusaku rwo guhinduranya umuyoboro (EMI / RFI) ku rugero rwemewe kandi bigatuma imiyoboro ifite frequency nyinshi ikora neza, ni ngombwa gushushanya neza imiyoboro n'imiterere y'imiyoboro nyayo n'ibice byayo. Iyo mu ikoreshwa rya “step-down”, ikiguzi cyo guhinduranya umuyoboro kiri hejuru ugereranyije n'icya “linear converter”. Ariko, uko igishushanyo cya “chip” gitera imbere, ikiguzi cyo guhinduranya umuyoboro kiri kugenda kigabanuka buhoro buhoro.

Umuhuza wa DC-DC ni igikoresho cyakira voltage yinjiye ya DC kandi gitanga voltage yinjiye ya DC. Voltage yinjiye ishobora kuba nini kurusha voltage yinjiye cyangwa se ikoreshwa mu buryo bunyuranye. Ibi bikoreshwa kugira ngo bihuze umutwaro n'amashanyarazi. Umuhuza woroshye wa DC-DC ugizwe n'imashini igenzura umutwaro kugira ngo ihuze kandi ivanemo umuriro.

Muri iki gihe, DC converters zikoreshwa cyane mu buryo bwo guhindura ingufu z'amashanyarazi ku modoka zikoresha amashanyarazi, imodoka zisukura amashanyarazi, moto zikoresha amashanyarazi n'izindi modoka zikoresha amashanyarazi. Zikoreshwa cyane kandi muri telefoni zigendanwa, MP3, kamera za digitale, ibyuma bicurangwa mu modoka zigendanwa n'ibindi bicuruzwa.
