Kurwanya simani abarwanya bifunze na sima.Ni uguhinduranya insinga zurwanya kuzengurutse igice cya farufari idashobora kwihanganira ubushyuhe, hanyuma ukongeramo ibikoresho birwanya ubushyuhe, birinda ubushuhe kandi birwanya ruswa kugirango birinde kandi bikosore hanze, hanyuma ushyire umubiri wurwanya-ibikomere mumwanya ikariso ya farashi, ukoresheje ibikoresho bidasanzwe bidashya kandi birwanya ubushyuhe.
Yuzuye kandi ifunzwe na sima.Hariho ubwoko bubiri bwaKurwanya sima: birwanya sima isanzwe hamwe na sima wire-ibikomere.Kurwanya sima ni ubwoko bwurwanya insinga.Nibishobora gukomera cyane kandi birashobora kwemerera kunyura mumigezi minini., imikorere yacyo ni nkiya résistoriste rusange, ariko irashobora gukoreshwa mubihe bifite amashanyarazi manini, nko guhuza urukurikirane na moteri kugirango ugabanye itangira rya moteri.Agaciro ko guhangana ntabwo muri rusange.Kurwanya sima bifite ibiranga ubunini bunini, kurwanya ihungabana, kurwanya ubushuhe, kurwanya ubushyuhe, kugabanuka kwinshi, nigiciro gito.Zikoreshwa cyane mumashanyarazi, ibikoresho byamajwi, kugabanya amajwi yumurongo, ibikoresho, metero, tereviziyo, imodoka nibindi bikoresho.Reka tuvuge ku ruhare rwabarwanya sima mumashanyarazi.
1. Imikorere yo gutanga amashanyarazi igabanya ubusanzwe ihujwe na voltage nkuru + 300V hamwe na E na C inkingi ya power switch.Igikorwa ni ukurinda amashanyarazi kutangirika no kwangiza ibice byayo mugihe amashanyarazi azimye.
2. Amashanyarazi atangira résistoriste, kurwanya hagati yumuyoboro wamashanyarazi nizunguruka itangira bihujwe na + 300V.Umuvuduko wa voltage hamwe nubu ni binini, bityo sima irwanya imbaraga nini nayo irakoreshwa.
3. Impanuka ya pulse yinjira mumashanyarazi hagati ya B, C, na E ya pole ya power power nayo ikoresha imbaraga za sima irwanya ingufu, nayo irinda umuyoboro wamashanyarazi.
