Sezvo musika wepasi rose wemotokari dzemagetsi uchikura nekukurumidza, kuvandudzwa kwezvivakwa zvekuchaja kwave chinhu chakakosha. Pakati peizvi, nzvimbo dzekuchaja dzeDC, senzira yepamusoro-soro uye iri nyore yekuchaja, dziri kuva musimboti wenetwork yekuchaja mota dzemagetsi.
Nzvimbo yekuchaja yeDC, sezita rayo, mudziyo unochaja mabhatiri emagetsi emotokari uchishandisa direct current. Zvichienzaniswa nenzvimbo dzekuchaja dzeAC dzechinyakare, nzvimbo dzekuchaja dzeDC dzine mabhenefiti akakosha ekumhanya kwekuchaja nekukurumidza uye kushanda zvakanaka. Dzinogona kushandura zvakananga simba reAC kubva pagrid kuita simba reDC, dzichichaja bhatiri remotokari zvakananga, nokudaro zvichideredza zvakanyanya nguva yekuchaja. Semuenzaniso, nzvimbo yekuchaja ye150kW DC inogona kuchaja mota yemagetsi kusvika 80% mumaminitsi makumi matatu, nepo nzvimbo yekuchaja yeAC inogona kutora maawa akati wandei mumamiriro akafanana.
Panyaya yetekinoroji, dhizaini nekugadzirwa kwezviteshi zvekuchaja zveDC zvinosanganisira matekinoroji akawanda akakosha. Chekutanga, kune tekinoroji yekushandura simba, iyo inoshandisa ma converter anoshanda zvakanaka kushandura simba reAC kuita simba reDC rakasimba. Chechipiri, kune sisitimu yekutonhodza; nekuda kwesimba rakawanda rinosanganisirwa mukuchaja nekukurumidza, sisitimu yekutonhodza inoshanda yakakosha pakuona kushanda kwakachengeteka uye kwakasimba kwemidziyo. Pamusoro pezvo, zviteshi zvekuchaja zveDC zvemazuva ano zvinosanganisa masisitimu ekudzora akangwara anogona kutarisa maparamita akasiyana-siyana munguva chaiyo panguva yekuchaja, senge voltage, current, uye tembiricha, zvichiita kuti kuchaja kushande uye kwakachengeteka.
Kuwanda kwezviteshi zvekuchaja zveDC kwakakosha kwete chete kune vanoshandisa mota dzemagetsi asiwo kune budiriro yezvakatipoteredza munharaunda yese. Chekutanga, kugona kuchaja nekukurumidza kunowedzera nyore kushandisa mota dzemagetsi, zvichibvisa "kunetseka kwevanoshandisa," uye nokudaro zvichikurudzira kushandiswa kwemotokari dzemagetsi. Chechipiri, zviteshi zvekuchaja zveDC zvinogona kubatanidzwa nemasisitimu ekugadzira simba rinogona kudzokororwa (senge simba rezuva nemhepo). Kuburikidza nemagrid akangwara, anogonesa kushandiswa zvakanaka kwemagetsi akasvibirira, anoderedza kuvimba nemafuta ekare, uye anoderedza kuburitsa kabhoni.
Parizvino, nyika zhinji nenzvimbo pasi rose dziri kukurudzira kuvaka kwezviteshi zvekuchaja zveDC. Semuenzaniso, China, semusika mukuru wemotokari dzemagetsi pasi rose, yakaisa zviteshi zvekuchaja zveDC mumaguta makuru nenzvimbo dzemigwagwa mikuru. Nyika dzinoverengeka dzeEurope dziri kushandawo kugadzira network dzekuchaja dzinomhanya zvakanyanya, dzichironga kuwana ruzivo rwakakwana mumakore anotevera. MuUnited States, kushandira pamwe pakati pehurumende nemakambani akazvimirira kuri kukurumidzisa kuvaka kwezviteshi zvekuchaja zveDC munyika yese.
Tichitarisa ramangwana, mikana yekuvandudzwa kwenzvimbo dzekuchaja dzeDC ine tariro huru. Nekufambira mberi kwetekinoroji, kumhanya kwekuchaja kuchawedzera, uye mutengo wemidziyo uchaderera zvishoma nezvishoma. Uyezve, mafambiro ekutsvaga ruzivo nekubatana kwenzvimbo dzekuchaja achaita kuti dzikwanise kuita basa rakakura mumaguta akangwara nekufambisa zvinhu zvine hungwaru.
Mukupedzisa, senzira iri pamberi mukugadzira tekinoroji yekuchaja mota dzemagetsi, nzvimbo dzekuchaja dzeDC dziri kushandura maitiro edu ekufamba uye mashandisirwo esimba. Dzinopa ruzivo rwekuchaja rwuri nyore kune vanoshandisa mota dzemagetsi uye dzinobatsira mukusimudzira nharaunda pasi rose. Mune ramangwana, tine chikonzero chakanaka chekutarisira kuti nekushandiswa kwakapararira kwenzvimbo dzekuchaja dzeDC uye kuvandudzwa kwetekinoroji kuri kuramba kuchienderera mberi, mota dzemagetsi dzichaunza nguva itsva yekukura nekukurumidza.
