Wannan bayanin kula na aikace-aikacen yana bayyana babban samar da wutar lantarki da batir madadin ta hanyar diode "ko" da&39;irar dabaru da haɗin kaya. Wannan gine-gine yana da sauƙin fahimta, amma lokacin da ƙarfin baturi ya wuce babban ƙarfin samar da wutar lantarki, diode "ko" da&39;irar dabaru za ta haɗa baturin, kuma babban wutar lantarki ba zai iya zama mai dacewa da zaɓaɓɓu ba. Wannan labarin yana ba da hanyar magance wannan matsala.

MAX931 comparator, comparator ginannen tushe 2%. Babban iko da batura masu amfani da aka haɗa zuwa lodi ta hanyar diode mai sauƙi "ko" da&39;irar dabaru. Koyaya, lokacin da ƙarfin baturi ya wuce babban ƙarfin samar da wutar lantarki, diode "ko" da&39;irar dabaru yana yin iko da baturin, kuma ba zai iya zabar babban wutar lantarki da hankali ba.

Hoto na 1 an ba da hanyar magance wannan matsala, ƙarfin wutar lantarki na babban wutar lantarki shine 7V zuwa 30V, ƙarfin wutar lantarki shine baturi 9V. Hoto 1.IC1MAX931 comparator ana amfani dashi don saka idanu babban ƙarfin wutar lantarki.

Lokacin da babban ƙarfin wutar lantarki ya faɗi ƙasa da 7.4V, ana iya dawo da shi zuwa batir ɗin da aka ajiye ta hanyar ƙaddamar da baturi mara kyau. MAX931 babban kwatancen wuta ne mai ƙarancin ƙarfi tare da 1.

182V band tazara. Lokacin aiki da kyau, kayan aikin kwatancen ba su da ƙasa, ana kashe tashoshi N-channel FET guda uku, kuma ƙarancin baturi ba komai bane, ta babban ƙarfin wutar lantarki. Lokacin da babban ƙarfin wutar lantarki ya ragu zuwa 7.

4V, mai kwatanta yana fitar da babban matakin. Zai kunna N-channel FET, ƙasa da baturi mara kyau, mai ƙarfi da baturi (Hoto 2). Hoto 2.

Babban ƙarfin wutar lantarki (tashar 3 a cikin Fig. 1) sannu a hankali yana raguwa, ƙarfin ƙarfin ƙofar N-channel FET ya zama babba (tashar 2). Wannan zai kunna baturi ta yadda ƙarfin fitarwa (channel 1) ya kai 9V.

Lokacin da babban ƙarfin wutar lantarki ya kai 8.4V, ana kashe N-channel FET, kuma babban wutar lantarki yana fitowa. D1, C1, da R6 na da&39;irar tuƙi na gate sun bayyana wani ɗan lokaci, wanda ke kawar da tsangwama na wucin gadi wanda kewayawar ke bayyana daga baturi zuwa babban tushen wutar lantarki, kuma waɗannan tsangwama na wucin gadi na iya haifar da microcontroller na tsarin don sake saitawa, wannan batu ɗaya game da yawancin tsarin ba shi da karbuwa.

Hoto na 3 yana nuna halaye lokacin da kewaye ba shi da tsangwama na wucin gadi. Lura: R3 da R4 sun saita ƙarfin lantarki na MAX931 zuwa 800mV don tabbatar da yanayin aiki daidai. Da fatan za a koma zuwa madaidaicin ƙimar juriya don bayanan MAX931.

Hoto 3. Lokacin da aka dawo da wutar lantarki da sauri, amsawar fitarwa ba ta wanzu cikin tsangwama na wucin gadi.
