I-AC vs DC Ukutshaja: Uthini umahluko?

Umbane ngumqolo wazo zonke izithuthi zombane. Noko ke, asinguye wonke umbane okumgangatho ofanayo. Kukho iintlobo ezimbini eziphambili zombane: i-AC (i-alternating current) kunye ne-DC (i-direct current). Kule post blog, siza kuphonononga umahluko phakathi kwe-AC kunye ne-DC yokutshaja kunye nendlela eyichaphazela ngayo inkqubo yokutshaja izithuthi zombane. Kodwa ngaphambi kokuba singene kwiinkcukacha, makhe sicacise into kuqala. Umsinga otshintshanayo koko kuvela kwigridi yamandla (oko kukuthi, isitshixo sendlu yakho). Umsinga othe ngqo ngamandla agcinwe kwibhetri yemoto yakho yombane

Ukutshaja kwe-EV: umahluko phakathi kwe-AC kunye ne-DC

 Amandla eDC

 Amandla e-DC (angoku ngqo) luhlobo lwamandla ombane aqukuqela kwicala elinye. Ngokungafaniyo namandla e-AC, atshintsha indlela amaxesha ngamaxesha, amandla eDC aqukuqela kwicala elingaguqukiyo. Ihlala isetyenziswa kwizixhobo ezifuna umthombo wamandla ongaguqukiyo, ozinzileyo, onje ngeekhompyuter, iithelevishini, kunye nee-smartphones. Amandla e-DC aveliswa zizixhobo ezifana neebhetri ze-EV kunye neepaneli zelanga, ezivelisa ukuhamba rhoqo kombane. Ngokungafaniyo namandla e-AC, anokuguqulwa ngokulula kumbane ohlukeneyo usebenzisa ii-transformers, amandla e-DC afuna inkqubo yokuguqula entsonkothileyo ukutshintsha amandla ombane.

Amandla e-AC

Amandla e-AC (alternating current) luhlobo lwamandla ombane atshintsha indlela ahamba ngayo. Isalathiso sombane we-AC kunye notshintsho lwangoku ngamaxesha athile, ngokuqhelekileyo kumaxesha angama-50 okanye ama-60 Hz. Isalathiso sombane okhoyo kunye nombane ubuya umva ngamaxesha athile, yiyo loo nto ibizwa ngokuba ngumbane otshintshanayo. Umbane we-AC uqukuqela kwiintambo zombane ukuya kungena ekhayeni lakho, apho ufikeleleka khona ngeendawo zombane.

I-AC kunye ne-DC yokutshaja okuhle kunye nokubi

 Ukutshaja kwe-AC:

1. Ukufikeleleka. Ukutshaja kwe-AC kuyafikeleleka kubantu abaninzi kuba kunokwenziwa kusetyenziswa umbane oqhelekileyo. Oku kuthetha ukuba abaqhubi be-EV banokubiza ekhaya, emsebenzini, okanye kwiindawo zikawonke-wonke ngaphandle kwezixhobo ezikhethekileyo okanye izibonelelo.
2. Ukhuseleko. Ukutshaja kwe-AC ngokuqhelekileyo kuthathwa njengokukhuselekileyo kunezinye iindlela zokutshaja kuba inika amandla kwi-sine waveform, engenakufane ibangele ukothuka kombane kunezinye iifom zamaza.

1. Ukufikeleleka. Ukutshaja nge-AC kubiza kancinci kunezinye iindlela zokutshaja kuba ayifuni zixhobo zikhethekileyo okanye iziseko zophuhliso. Oku kuyenza ibe lukhetho olungabizi kakhulu kubantu abaninzi.

Iingozi zokutshaja nge-AC:

1. Amaxesha okutshaja kancinci.Iitshaja ze-AC zinamandla alinganiselweyo okutshaja kwaye zicotha kunezikhululo ze-DC, ezinokuthi zibe yingozi kwii-EVs ezifuna ukutshaja ngokukhawuleza endleleni, ezifana nezo zisetyenziselwa ukuhamba umgama omde. Amaxesha okutshaja ngokutshaja kwe-AC anokuqala kwiiyure ezimbalwa ukuya kwiintsuku, ngokuxhomekeke kumthamo webhetri.

1. Ukusebenza kakuhle kwamandla.Iitshaja ze-AC aziwonga amandla njengezikhululo zokutshaja ezikhawuleza kakhulu kuba zifuna isiguquli-mandla ukuguqula amandla ombane. Le nkqubo yokuguqula iphumela ekulahlekeni kwamandla athile, nto leyo enokuba yingozi kwabo banenkxalabo malunga nokusebenza kakuhle kwamandla.

Ngaba i-AC okanye i-DC ingcono ukutshaja?

Oku kuya kuxhomekeka kwiimfuno zakho zokutshaja. Ukuba uqhuba imigama emifutshane yonke imihla, ngoko ke ukongezwa rhoqo usebenzisa itshaja ye-AC kufuneka yanele. Kodwa ukuba uhlala usendleleni kwaye uqhuba imigama emide, ukutshaja kwe-DC yeyona ndlela ingcono, njengoko unokuhlawulisa ngokupheleleyo i-EV yakho ngaphantsi kweyure. Qaphela ukuba ukutshaja okukhawulezayo rhoqo kunokubangela ukuhla kwebhetri njengoko amandla aphezulu evelisa ubushushu obuninzi.

Ngaba ii-EVs zisebenza kwi-AC okanye kwi-DC?

Izithuthi zombane zisebenza ngokuthe ngqo. Ibhetri kwi-EV igcina amandla ombane kwifomathi ye-DC, kunye nemoto yombane enika amandla isithuthi sisebenza kumandla e-DC ngokunjalo. Ngeemfuno zakho zokutshaja kwe-EV, jonga ingqokelela ye-Lectron yeetshaja ze-EV, iadaptha, kunye nokunye kweTesla kunye neJ1772 EVs.
