Isibani esiphuthumayo sezentengiso sinomsebenzi wokonga kakhulu, kodwa ngokuvamile akukho ukuvikeleka kokukhishwa. Uma ibhethri likhishwa ngokweqile, amakristalu e-sulfate azokwenziwa abe mkhulu, angafaki nje ukumelana nogesi wepuleti, kodwa kunzima ukuwenza ukubuyisela ngesikhathi sokushaja, kuthinte ngqo umthamo nokuphila kwebhethri. Isekhethi ehlinzekwe lapha ingavikela ibhethri ekushajweni ngokweqile nasekuchitheni ngokweqile.

Uma amandla e-AC esebenza, amandla okulayisha avela kusilawuli; uma amandla e-AC engavumelekile, umthwalo udluliselwa ngokuzenzakalela ebhethrini elingu-6V. Lapho amandla e-AC ebuyiselwa, umthwalo ubuyela emandleni yisilawuli, futhi ibhethri iqala ukushaja. Isifunda sonke singahlukaniswa sibe izingxenye ezine: ukunikezwa kwamandla, ukushintshwa kwesifunda, isifunda sokuvikela ukukhishwa ngokweqile kanye nesifunda sokuvikela ukushaja ngokweqile.

Ukunikezwa kwamandla kwe-AC kokunikezwa kwamandla kudlula ku-transformer X1 buck, isilungisi sebhuloho i-BR1 siyalungiswa, futhi i-capacitor C1 iyahlungwa, futhi i-chip 7806 (IC1) iqiniswa ibe ngumthombo wamandla we-6V. Isifunda sokushintsha siqukethe i-transistor T1 kanye nezingxenye ze-RL1 ezidluliswayo. Uma amandla e-AC esebenza, i-T1 iyavulwa, ukuze i-RL1 (6V, 100Ω) imunce, i-LED1 eluhlaza ikhanyise, ibonise ukuthi amandla e-AC ayasebenza.

Ngesikhathi esifanayo, isilawuli sikhipha othintana naye ovamise ukuvaleka ongu-N/C kanye ne-RL3 ye-RL1 ukuze axhume kumthwalo, kuyilapho ibhethri elingu-6V lishajwa ngoxhumana naye ovamise ukuvaleka ongu-N/C we-RL2. I-T1 ivaliwe lapho amandla e-AC engavumelekile. Ukukhishwa kwe-RL1.

Imiphumela Umthwalo uyashintsha usuka koxhumana naye ovamise ukuvaleka ongu-N/C we-RL1 usuka kubhethri elingu-6V, ngaleso sikhathi i-LED1 icishiwe, okubonisa ukuthi amandla e-AC awekho. Isekhethi yokuvikela ukukhishwa ngokweqile kwebhethri iqukethe i-IC3, T3, RL3 nezinye izakhi. Lapho ibhethri selishajwe kakhulu (ngaphansi kuka-5.

5V), i-voltage ku-IC3 inverted input (2) iphakeme kune-voltage ekufakweni kwayo kwe-homogenic (3), futhi okukhiphayo kwe-IC3 kuphansi, i-T3 ivuliwe, i-RL3 (5V, 100Ω, umthwalo unqanyuliwe ebhethri ye-6V ngenxa yokwehlukana kokuxhumana no-N / C, ngaleyo ndlela kuvimbele ukukhishwa ngokweqile. Ngesikhathi esifanayo, i-LED3 iyakhanyisa, okubonisa ukuthi ibhethri likhishwe ngokweqile. Lapho amandla e-AC ebuyiselwa, ibhethri lishajwa ngu-RJ2 contact N/C.

Lapho i-voltage yebhethri ifinyelela ku-5.5V. Okukhiphayo kwe-IC3 kubuyela kumandla aphezulu.

I-T3 ivaliwe, i-RL3 ikhishwa, futhi umthwalo uxhunywe ekuphumeni komlawuli. Isekhethi yokuvikela ukushaja ngokweqile yebhethri iqukethe i-IC2, T2, RL2 nezinye izingxenye. Uma amandla e-AC esebenza, futhi i-voltage yebhethri ingaphansi kuka-6.

6V. Njengoba i-voltage eku-IC2 inverting input 2 iphakeme kune-voltage ekufakweni kwesigaba esifanayo esingu-3, ​​okukhiphayo kwe-IC2 kuphansi, i-T2 ivaliwe, futhi i-RL2 (6V.100Ω) ihlala isesimweni sokukhululwa.

Ngalesi sikhathi, ibhethri ishajwa ngokuqhubekayo ngothintana naye we-N/C we-RL2. Lapho i-voltage yebhethri ifinyelela ku-6.6V.

Okukhiphayo kwe-IC2 kuphezulu, i-T2 ivuliwe, i-RJ2 iyamuncwa, futhi ukushaja kuyamiswa. Ngalesi sikhathi, i-LED2 iyakhanyisa, okubonisa ukuthi ibhethri ishaja kakhulu. Emidwebeni, i-D2, i-D3 ivikela i-RL2, i-RL3 emthelela we-anti-electromotive force.
