Inzuzo ephambili yetshaja yemoto kukuba isebenzisa amandla e-AC angaphandle kweshelufu, anokufakwa kuyo nayiphi na enye yeebhiliyoni zeevenkile ezifakwe kwisakhiwo ngasinye ngocingo olunye.
Ukutshaja kweNqanaba loku-1 kwe-AC kusebenzisa umbane wesigaba esinye, unikezelo lwamandla lwe-120V lumalunga ne-1.9KW, i-220V-240V yombane imalunga ne-3.7KW.Le yeyona ndlela ixhaphakileyo yokuhlawula kumakhaya abucala.
Nangona kunjalo, iinkampani zikholisa ukusebenzisa umthombo wamandla onezigaba ezithathu ukutshaja, onokunyusa amandla akhoyo etshaja ezisebhodini ukuya malunga ne-20kW, ngokukhawuleza kakhulu kunenqanaba lokuqala lokutshaja.
Ukutshaja kwe-AC yeyona ndlela ibhetyebhetye kakhulu yokuhlawula, njengoko isikhululo sokutshaja sinokubonelela ngoluhlu olupheleleyo lweemfuno zokutshaja ngokusekelwe kwindlela yokuphila yomsebenzisi kunye nokusetyenziswa kwesithuthi.Ukuba isithuthi sisetyenziselwa ukuhamba emini kuphela, ukutshaja ebusuku kulula kakhulu.Ukutshaja kwe-AC akulunganga ukutshaja okongeziweyo kuba ixesha lokutshaja lide kakhulu kwaye umgama ofunekayo ungaphezulu koluhlu lwesithuthi.
Izinto ezisetyenziswayo kwiitshaja zemoto
Izixhobo ze-passive ezifana ne-magnetic elements kunye ne-capacitors zidlala indima ephambili kuyo yonke imiba yeetshaja ezisebhodini.Isiguquli sokunyusa esenza isiphelo sangaphambili se-PFC siya kuba nesihluzo se-EMC eqhelekileyo, i-capacitors yokucoca, iikhoyili ze-PFC, kunye ne-DC link capacitor ebonelela ngokugcina ukutshaja phakathi kwenqanaba lokunyusa kunye neshaja ekwibhodi.
Abaguquli be-LLC basetyenziswa ngokubanzi kwizicelo zamashishini kunye nabathengi.Nangona kungekho mveliso ithile ikhutshelwayo isetyenziswayo, izinto zemagneti zisetyenziselwa ukwahlula iziguquli kunye nezihluzo ze-EMC eziphumayo, kunye neecapacitors ezahlukeneyo.
Amandla okwamkela ukutshaja ngaphandle kwamacingo kukhokelele kwimfuno ebanzi yamacandelo angaxutywanga, kuqukwa iikhoyili zothumelo lwamandla (ukuthumela nokwamkela), njengoko kubonisiwe ngasekunene, kunye nezixhobo zokujonga izinto ezikufutshane ukuqinisekisa ukuba isithuthi silungelelaniswe kakuhle netshaja.
Nangona iinkqubela phambili ezininzi zamva nje zijolise kumandla ezixhobo ze-elektroniki ze-semiconductor ezifana ne-MOSFET kunye ne-IGBT kunye nolawulo oluhambelana nazo, ezimbalwa zezi zixhobo ziye zakwazi ukuqonda amandla azo kumacandelo angenayo ngaphandle kokuphuculwa okuhambelanayo ekusebenzeni kwazo okuxhomekeke kunye nezihlanganisi kunye neentambo.
Kwizicelo ezininzi, izichasi ezininzi zisetyenziswa nje ngokunxuseneyo ukujongana nelahleko yamandla efunekayo.Nangona oku kunika isisombululo kwinqanaba lesekethe, kwandisa inani lamacandelo, iindleko, kunye nendawo yebhodi efunekayo - akukho nanye into efanelekileyo kwindawo yemoto.Utshintsho lwakutsha nje lwaluyinto yokuqala yokumelana namandla aphezulu anikezelwe ngesiqinisekiso se-AEC-Q200 (ngasekhohlo).Ezi zixhobo ze-1% zokunyamezela zibonelelwa kwi-design ye-insulated package ukuze zifakwe ngqo kwi-radiator, apho zilinganiswe ukuya kwi-800W.Oku kuchithwa kwamandla aphezulu kuvumela izixhobo ezininzi zamandla aphantsi ukuba zitshintshwe yi-resistor enye, okanye (ngenxa yomthamo wayo we-pulse) i-resistor enkulu ye-wire-nxeba inokutshintshwa, ukugcina indawo yebhodi.
I-inductor licandelo elinokuthi, ukuba alikhethwanga ngononophelo, lingonakaliswa kukubonakaliswa kwexesha elide kubushushu kunye nokungcangcazela.Nangona kunjalo, imodeli ehexayo idibana nemigangatho ye-AEC-Q200, efana nentsimbi edityanisiweyo yokuqinisa amandla kunye nokubaleka kwebhanti kunye nesihluzi.Iinguqulelo zamva nje zibonelela ngokumelana nokungcangcazela okuphezulu kwaye ziyakwazi ukusebenza kumaqondo obushushu ukuya kuthi ga kwi-150 ° C (kubandakanywa nokuzifudumeza), ngelixa ugcina uzinzo olugqwesileyo lwe-inductance kuloluhlu lobushushu olwandisiweyo.Ulwakhiwo olukhuselayo luphelisa ukuvuza kwamagnetic, ngaloo ndlela lunciphisa naziphi na iingxaki zokuphazamiseka kombane.
EVumthengisi wetshaja osebhodini
DCNEitshaja esebhodiniisetyenziselwa ikakhulu izithuthi ezixubileyo, izithuthi zombane ezisulungekileyo, iibhasi zombane, izithuthi zokuhambisa umbane kunye nezinye izithuthi zamandla amatsha, kwaye ifanelekile ukutshaja i-lithium iron phosphate, i-lithium manganese acid, i-asidi ekhokelayo kunye nezinye iibhetri zamandla ezithuthi.Qala ishishini lakho lesikhululo sokutshaja i-EV ngeDCNE.
Ukufumana ixabiso lexabiso lamva nje letshaja ekwibhodi okanye inkxaso yobugcisa, ncedaQhagamshelana nathikwaye ugcwalise iinkcukacha zakho, kwaye siya kubuyela kuwe ngaphakathi kweeyure ezingama-24.
