(1) Mugihe habaye umuriro w'amashanyarazi, 'reba, impumuro, ubaze, upime'

Reba: Fungura igikonoshwa cyamashanyarazi, reba niba fuse yahuwe, hanyuma urebe imiterere yimbere yumuriro.Niba hari ahantu hatwitswe cyangwa ibice byacitse ku kibaho cya PCB cyo gutanga amashanyarazi, intego igomba kwibanda ku kugenzura ibice hamwe n’ibice by’umuzunguruko bifitanye isano hano.

Impumuro: Impumuro niba hari impumuro yaka imbere mumashanyarazi hanyuma urebe niba hari ibice byahiye.

Ikibazo: Nshobora kubaza inzira yo kwangirika kw'amashanyarazi no kumenya niba hari ibikorwa bitemewe byakozwe ku gutanga amashanyarazi.

Igipimo: Mbere yo gukongeza, koresha multimeter kugirango upime voltage kumpande zombi za capacitori.Niba ikosa ryatewe no kunanirwa kwamashanyarazi ya ecran ya LED cyangwa uruziga rufunguye rwumuyoboro wa switch, mubihe byinshi, voltage kumpande zombi za capacitori ya voltage nini ntisohoka, ikaba irenga volt 300.Witondere.Koresha multimeter kugirango upime imbere kandi uhindure guhangana kumpera zombi z'umurongo wa AC hamwe nuburyo bwo kwishyuza bwa capacitor.Agaciro ko guhangana ntigomba kuba hasi cyane, bitabaye ibyo hashobora kubaho uruziga rugufi imbere yumuriro w'amashanyarazi.Ubushobozi bugomba kuba bushobora kwishyuza no gusohora.Hagarika umutwaro kandi upime ubukana bwubutaka bwa buri tsinda ryibisohoka.Mubisanzwe, urushinge rwa metero rugomba kugira capacitori yishyuza no gusohora ihindagurika, kandi icyanyuma kigomba kuba agaciro kokurwanya kwimyuka yumuzunguruko.

(2) Imbaraga zo gutahura

Nyuma yo gucana, reba niba amashanyarazi yatwitse umuriro hamwe nibice bimwe bisohora umwotsi.Niba aribyo, hagarika amashanyarazi mugihe gikwiye cyo kubungabunga.

Gupima niba hari 300V isohoka kumpande zombi za capacitori yumuriro mwinshi.Niba atari byo, shimangira kugenzura diode ikosora, ubushobozi bwa filteri, nibindi.

Gupima niba coil ya kabiri ya transfert yo hejuru-ifite impinduka.Niba nta bisohoka, jya wibanda ku kugenzura niba umuyoboro wangiritse wangiritse, niba urimo kunyeganyega, ndetse n’umuzunguruko ukora.Niba ihari, shimangira kugenzura diode ikosora, kayunguruzo ya capacitor, inzira-eshatu igenzura imiyoboro, nibindi kuri buri ruhande rusohoka.

Niba amashanyarazi atangiye agahagarara ako kanya, ni muburyo bukingiwe.Umuvuduko wa chip yo kurinda chip ya PWM urashobora gupimwa muburyo butaziguye.Niba voltage irenze agaciro kagenwe, byerekana ko amashanyarazi ari mumurinzi, kandi impamvu yo kurinda igomba kugenzurwa neza.
