Ni uruhe ruhare inductor ya SMD igira mu matara azigama ingufu za LED?

Kubera ko indimu ya chip ishobora kongera ubuzima bwa serivisi kubicuruzwa byinshi bya elegitoroniki byabaguzi, kuzamura ubwiza bwibicuruzwa, ubuziranenge budasanzwe, nibikorwa, byashyizwe mubikorwa nababikora benshi.

Ntabwo ikoreshwa gusa mubikoresho bitanga amashanyarazi, ahubwo ikoreshwa nibikoresho byamajwi, ibikoresho bya terefone, ibikoresho byo murugo nibindi bikoresho bya elegitoroniki n’amashanyarazi, kugirango ibimenyetso bya electroniki ya magnetiki bitabangamirwa, kandi icyarimwe, ntibibangamira cyane ibimenyetso cyangwa imirasire ya electromagnetic itangwa nibindi bikoresho bikikije. .

Amatara azigama ingufu akoreshwa cyane mubuzima bwacu; n'amatara ya LED azigama ingufu agizwe ahanini na diode itanga urumuri rwinshi; ni ubwoko bwurumuri rutwara imbaraga nke kandi rufite ubuzima burebure.

Umuzenguruko w'imbere w'itara rizigama ingufu za LED ni insimburangingo y'amashanyarazi, ikubiyemo cyane cyane imashanyarazi ya electrolytike, résistoriste, inductors, ceramic capacitor, nibindi. Muri byo, umubare muto ugereranije ni amashanyarazi ya chip, kandi uruhare rwayo ni ngombwa .

ni cyane cyane guhagarika AC na DC, no guhagarika inshuro nyinshi na frequency nkeya (kuyungurura). Birumvikana ko amashanyarazi azenguruka cyane AC na DC. Birashobora kugaragara ko kurwanya imbaraga za chip power inductor kuri DC hafi ya zeru.

Ukurikije uko ibintu bimeze ubu umuzunguruko wemerera kunyura, induction ya chip ibuza kunyura kuri point ya AC, irinda ikibaho cyumuzunguruko kwangirika, kandi cyongera cyane ubuzima bwumurimo wa LED.
