Isingeniso：
Isimiso sobuchwepheshe bokukhipha i-pulseithuluzi lokulungisa ukulinganisa ibhethriikakhulukazi kusekelwe esignalini ye-pulse ukuze kwenziwe imisebenzi ethile yokukhipha ibhethri ukuze kufezwe imisebenzi yokulinganisa nokulungisa ibhethri. Okulandelayo yisingeniso esiningiliziwe sobuchwepheshe bokukhipha i-pulse bethuluzi lokulungisa i-equalization yebhethri:
Ukukhiqizwa kwesignali ye-pulse
Iithuluzi lokulungisa ukulinganisa ibhethriinomshini okhethekile wokukhiqiza isignali ye-pulse ngaphakathi, ovame ukwakhiwa yisekethe yokuzulazula, isekethe yokulawula, njll. Isekethe yokuzulazula ingakhiqiza isignali ye-pulse enemvamisa ephezulu noma ephansi, futhi amapharamitha afana nemvamisa, ububanzi kanye nokuphakama kwalezi zimpawu kungalungiswa njengoba kudingeka. Isekethe yokulawula ilawula ngokunembile isignali ye-pulse ekhiqizwa yisekethe yokuzulazula ngokuya ngesimo esithile sebhethri kanye nohlelo oluhleliwe ukuze kukhishwe ukulandelana kwe-pulse okuhlangabezana nezidingo.
Inqubo yokukhipha i-pulse
Ukuxhumeka nebhethri: Xhuma umlungisi wokulinganisela ibhethri nebhethri ukuze kucutshungulwe ngokusebenzisa isikhombikubona esithile, bese isekethe yokukhipha i-pulse yomlungisi yakha iluphu evaliwe neseli yebhethri noma ibhethri.
Isimiso sokukhipha i-pulse: Uma isignali ye-pulse isezingeni eliphezulu, i-switch element (njenge-transistor yamandla, njll.) ku-pulse discharge circuit iyavulwa, bese ibhethri likhipha i-charge nge-discharge circuit ukuze lenze i-discharge current. Ngesikhathi se-low level ye-pulse signal, i-switch element iyacinywa bese inqubo yokukhipha imiswa. Ngokuphinda le nqubo yokukhipha i-conduction ephezulu kanye ne-low level cut-off, kwakheka i-pulse discharge.
Ukukhishwa Nokudluliselwa Kwamandla: Ngesikhathi senqubo yokukhishwa kwe-pulse, amandla amakhemikhali angaphakathi kwebhethri aguqulwa abe amandla kagesi futhi akhishwe ngesekethe yokukhishwa. Kwiseli ngayinye yebhethri ephaketheni lebhethri, uma kukhona ukungalingani kwe-voltage, iseli yebhethri ene-voltage ephezulu izokhipha ukushaja okwengeziwe ngesikhathi senqubo yokukhishwa kwe-pulse, kuyilapho iseli yebhethri ene-voltage ephansi izokhipha ukushaja okuncane. Ngale ndlela, ngokulawula amapharamitha e-pulse nesikhathi sokukhishwa, njll., ukushaja kweseli ngayinye yebhethri kungahlala kufana kancane kancane, ngaleyo ndlela kufezwe ukulinganisa kwebhethri.
Umphumela ebhethri
Ukuqeda i-polarization: Ibhethri lizokhiqiza i-polarization ngesikhathi senqubo yokushaja nokukhipha ishaja, okuholela ekunciphiseni ukusebenza kwebhethri. Ubuchwepheshe bokukhipha i-pulse bungasebenzisa umphumela okhethekile wezimpawu ze-pulse ukuze kuqedwe ngempumelelo i-concentration polarization kanye ne-electrochemical polarization yebhethri ngesikhathi senqubo yokukhipha ishaja. Isibonelo, ngesikhathi esifushane sokukhishwa kwe-pulse, ukusatshalaliswa kwe-ion concentration ngaphakathi kwebhethri kungabuyiselwa ngezinga elithile, ngaleyo ndlela kuncishiswe umthelela we-polarization ekusebenzeni kokushaja nokukhipha ibhethri, futhi kuthuthukiswe ukusebenza kahle kokushaja nokukhipha ibhethri kanye nokuguqulwa kwayo.
Ukulungisa i-sulfation: Ezinhlotsheni zamabhethri ezifana namabhethri e-lead-acid avame ukuncibilika, ubuchwepheshe bokukhipha i-pulse bunomphumela othile wokulungisa. Lapho kuvela ama-sulfide kuma-plate ebhethri, ukukhishwa kwe-pulse okunemvamisa efanele kanye ne-amplitude kungakhiqiza imisinga emikhulu esheshayo ukuze kuthinte ama-sulfide, okubangela ukuthi isakhiwo sekristalu le-sulfide sishintshe, sibole kancane kancane futhi sincibilike sibe yi-electrolyte, ngaleyo ndlela kubuyiselwe izinto ezisebenzayo zama-plate ebhethri futhi kuthuthukiswe umthamo webhethri kanye nokusebenza kwayo.
Iphakethe lebhethri elilinganiselayo: Ephaketheni lebhethri, amaseli ebhethri ahlukene angaba nomehluko ngomthamo, ukumelana kwangaphakathi, njll. ngenxa yezici ezifana nenqubo yokukhiqiza kanye nendawo yokusetshenziswa, okuholela ekungalingani ngesikhathi senqubo yokushaja nokukhipha ishaja.ithuluzi lokulungisa ukulinganisa ibhethriUbuchwepheshe bokukhipha i-pulse bulawula ukukhishwa kweseli ngayinye yebhethri ngamazinga ahlukahlukene, okuvumela amaseli ane-voltage ephezulu kanye nomthamo omkhulu ukuthi akhiphe ugesi owengeziwe, kuyilapho amaseli ane-voltage ephansi kanye nomthamo omncane ekhipha ugesi omncane. Ekugcineni, kufinyelela ibhalansi yamapharamitha afana ne-voltage namandla eseli ngalinye ephaketheni lebhethri, ngaleyo ndlela kuthuthukiswe ukusebenza okuphelele kanye nokuphila kwenkonzo kwephakethe lebhethri.
Isiphetho
