MuriLEDgutwara amashanyarazi azenguruka ashingiye ku ihame ryo kugabanya ingufu za capacitori, ihame ryo kugabanya ingufu za voltage ni hafi gutya: mugihe amashanyarazi ya sinusoidal AC akoreshwa kumuzunguruko wa capacitori, kwishyuza kumasahani abiri ya capacitor hamwe numuriro w'amashanyarazi hagati amasahani ni imikorere yigihe. Nukuvuga: agaciro keza na amplitude ya voltage na current kuri capacitor nayo ikurikiza amategeko ya Ohm. Nukuvuga ko, iyo voltage amplitude hamwe ninshuro kuri capacitori bikosowe, AC ya sinusoidal ihamye izatemba. Gutoya ya capacitif reaction ni nini, agaciro ka capacitance nini, kandi nini nini itembera muri capacitor. Niba umutwaro ukwiye uhujwe murukurikirane kuri capacitor, kugabanuka kwamashanyarazi birashobora kuboneka, bishobora gusohoka binyuze mugukosora, kuyungurura no guhagarika imbaraga. Ikibazo kigomba kwitabwaho hano nuko muri iyi sisitemu yumuzunguruko, capacitor ikoresha ingufu zumuzunguruko gusa, ariko ntikoreshe ingufu, bityo imikorere yumuzunguruko wa capacitori iri hejuru cyane.

Mubisanzwe, imiyoboro nyamukuru yo gutwara yaLEDamashanyarazi ashingiye kumahame ya capacitor buck azaba agizwe na capacitori ya Buck, imiyoboro igabanya imipaka, gukosora akayunguruzo hamwe na voltage itunganya shunt. Muri byo, capacitori yamanutse ihwanye na transformateur yo kumanuka mumashanyarazi asanzwe ahinduranya umuzunguruko, uhujwe neza numuyoboro wamashanyarazi wa AC kandi ukaba ufite amashanyarazi hafi ya yose u, bityo rero capacitori yicyuma idafite polarite Byahiswemo. Kuri ubu iyo imbaraga zifunguye, birashobora kuba impinga yo hejuru yibiciro byibyiza cyangwa bibi byikurikiranya bya U. muriki gihe, umuyaga uhita uba munini cyane. Kubwibyo, inzitizi zigabanya ubukana zigomba guhuzwa mukuzunguruka kugirango zizere umutekano wumuzunguruko, niyo mpanvu nyamukuru ituma imiyoboro igabanya imipaka ari ngombwa. Igishushanyo gisabwa cyo gukosora no kuyungurura umuzunguruko ni kimwe n’ibisanzwe DC isanzwe igenzura amashanyarazi. Impamvu ituma voltage ihindura shunt ikenewe ni uko muri voltage igabanya umuzunguruko, agaciro keza k'umuyaga I karahagaze kandi ntigahinduka no guhindura imizigo. Kubwibyo, muri voltage stabilizing circuit, hagomba kubaho umuzunguruko wa shunt kugirango usubize impinduka zumutwaro.
