Nyuma yimyaka 15 yiterambere, ibinyabiziga bishya byamashanyarazi byashizeho ububiko bwa tekiniki. Guhitamombere yo kwishyuzaigena umuvuduko wikinyabiziga mbere yo kwishyuza, ingano yumwanya ufitwe nubushake bwo kwishyuza mbere, umutekano wumuriro wumuriro wumuriro mwinshi, kwizerwa no guhagarara neza.
Imbere yo kwishyurwa iri mumodoka ifite ingufu nyinshi za voltage kuri capacitor mugitangira gahorokwishyuza, niba nta re-re-résistoriste, amashanyarazi yumuriro azaba manini cyane kugirango avunike ubushobozi. Imbaraga z'umuvuduko mwinshi wongewe kuri capacitor, bihwanye nigihe gito-cyumuzunguruko ako kanya, umuyoboro mugufi ukabije uzangiza ibice byamashanyarazi menshi. Kubwibyo, mugihe utegura uruziga, birwanya kwishyuza mbere yo kwishyurwa bigomba kwitabwaho kugirango umutekano wumuzunguruko.
Hano hari ahantu habiri mumashanyarazi menshi yumuriro wamashanyarazi ahombere yo kwishyuzaikoreshwa, aribwo bugenzuzi bwa moteri mbere yumuzunguruko hamwe n’umuriro mwinshi wa voltage mbere yumuriro. Umugenzuzi wa moteri (umuzenguruko wa inverter) afite capacitor nini, igomba kubanza kwishyurwa kugirango igenzure imiyoboro yumuriro.
Ukurikije igishushanyo mbonera cyagaragaye cyabonetse: ceramic resistance ni précarge ifatika, gusohora nibindi bisabwa. Ifite ubushyuhe bwihariye kandi irashobora gukuramo ingufu nyinshi mugihe cyo kubanza kwishyuza mugihe gito.
