Isibane sorhwebo esingxamisekileyo sinomsebenzi wolondolozo olugqithisileyo, kodwa kaninzi akukho khuseleko lokukhutshwa. Ukuba ibhetri ikhutshwe ngokugqithiseleyo, i-crystals ye-sulfate iya kwenziwa ibe nkulu, engafaki nje ukuchasana kombane weplate, kodwa kunzima ukuyibuyisela ngexesha lokutshaja, ichaphazela ngokuthe ngqo umthamo kunye nobomi bebhetri. Isekethe ebonelelwe apha inokukhusela ibhetri kwi-overcharge kunye nokukhupha ngaphezulu.

Xa amandla e-AC esebenza, amandla omthwalo ovela kumlawuli; ukuba amandla e-AC akasebenzi, umthwalo uthunyelwa ngokuzenzekelayo kwibhetri ye-6V. Xa amandla e-AC ebuyiselwa, umthwalo ubuyela kumandla ngumlawuli, kwaye ibhetri iqala ukutshaja. Isekethe yonke inokwahlulwa ibe ngamacandelo amane: unikezelo lwamandla, ukutshintshwa kwesekethe, isekethe yokukhusela ukukhutshwa okugqithisileyo kunye nesekethe yokukhusela i-overcharge.

Umbane we-AC wonikezelo lwamandla udlula kwi-buck ye-transformer ye-X1, i-BR1 yokulungisa ibhulorho iyalungiswa, kwaye i-capacitor C1 iyahluzwa, kwaye i-chip 7806 (IC1) izinzile kwi-6V yamandla ombane. Isekethe yokutshintsha iquka i-transistor T1 kunye ne-relay RL1 amacandelo. Xa amandla e-AC esebenza, i-T1 ivuliwe, ukuze i-RL1 (6V, 100Ω) ifakwe, i-LED1 eluhlaza ikhanyisa, ibonisa ukuba amandla e-AC ayasebenza.

Ngelo xesha, umlawuli ukhupha umnxibelelwano oqhelekileyo ovaliweyo N / C kunye ne-RL3 ye-RL1 ukuxhuma kumthwalo, ngelixa ibhetri ye-6V ihlawuliswa ngoqhagamshelwano oluqhelekileyo oluvaliweyo N / C yeRL2. I-T1 ivaliwe xa amandla e-AC engavumelekanga. Ukukhutshwa kwe-RL1.

Iziphumo Umthwalo utshintsha ukusuka kuqhagamshelwano oluqhelekileyo oluvaliweyo lwe-N / C ye-RL1 ukusuka kwibhetri ye-6V, ngelo xesha i-LED1 icinyiwe, ebonisa ukuba amandla e-AC akakho. Isiphaluka esikhuselayo sokukhupha ibhetri siqukethe i-IC3, T3, RL3 kunye nezinye izinto. Xa ibhetri ikhutshwe kakhulu (ngaphantsi kwe-5.

5V), i-voltage kwi-IC3 inverted input (2) iphezulu kune-voltage kwi-input yayo ye-homogenic (3), kwaye i-IC3 imveliso iphantsi, i-T3 ivuliwe, i-RL3 (5V, i-100Ω, umthwalo unqanyuliwe kwi-6V ibhetri ngenxa yokudibanisa N / C ukwahlukana, ngaloo ndlela ukuthintela ukukhutshwa ngokugqithiseleyo. Ngelo xesha, i-LED3 ikhanyisa, ebonisa ukuba ibhetri ikhutshwe kakhulu. Xa amandla e-AC ebuyiselwe, ibhetri ihlawuliswa nguRJ2 umfowunelwa N / C.

Xa amandla ombane ebhetri afikelela kwi-5.5V. Imveliso ye-IC3 ibuyela kumandla aphezulu.

I-T3 ivaliwe, i-RL3 ikhutshwe, kwaye umthwalo uxhunywe kwimveliso yomlawuli. Ukutshaja okugqithisileyo kwesekethe yokukhusela ibhetri iquka i-IC2, T2, RL2 kunye namanye amacandelo. Xa amandla e-AC esebenza, kwaye amandla ombane ebhetri angaphantsi kwe-6.

6V. Ekubeni i-voltage kwi-IC2 i-inverting input 2 iphezulu kune-voltage kwi-input yesigaba se-3, ukuphuma kwe-IC2 iphantsi, i-T2 ivaliwe, kwaye i-RL2 (6V.100Ω) ihlala kwindawo yokukhululwa.

Ngeli xesha, ibhetri ihlawulwe ngokuqhubekayo ngoqhagamshelwano lwe-N / C lwe-RL2. Nje ukuba amandla ombane ebhetri afikelele kwi-6.6V.

Imveliso ye-IC2 iphezulu, i-T2 ivuliwe, i-RJ2 ifunnyiwe, kwaye ukutshaja kuyekile. Ngeli xesha, i-LED2 iyakhanyisa, ebonisa ukuba ibhetri itshaja kakhulu. Kwimizobo, i-D2, i-D3 ikhusela i-RL2, i-RL3 kwimpembelelo ye-anti-electromotive force.
