  1. Isitimela sikagesi sokulungisa: njengesitimela sikagesi esigabeni esisodwa-DC, isitimela sikagesi esetshenziswa kakhulu kunazo zonke ze-AC. Esitimeleni sokulungisa ugesi, i-AC yesigaba esisodwa se-high-voltage AC kunethiwekhi yokuxhumana yehliswa yi-traction transformer ekuqaleni, bese kuthi i-AC yesigaba esisodwa iguqulwe ibe yi-DC yidivayisi yokulungisa eyakhiwe nge-silicon rectifier element noma i-thyristor , futhi yanikezwa kumoto yokudonsa. Yenza ukulawulwa kwesigaba kulungisi ukushintsha amandla kagesi alungisiwe ukuze ulungise isivinini sesitimela.
  2. Isitimela sikagesi sesigaba esisodwa: yaziwa nangokuthi isitimela esiqondile se-AC kagesi, kusetshenziswa isigaba esisodwa se-commutator traction motor. Amandla we-high-voltage AC kunethiwekhi yokuxhumana azonciphisa i-voltage yi-transformer, bese ihlinzekwa emotweni yokudonsa ngqo.
  3. Isitimela sikagesi se-AC-DC-AC: eyaziwa nangokuthi isigaba sesitimela esisodwa sikagesi sesigaba esisodwa. Amandla we-high-voltage AC kunethiwekhi yokuxhumana aqale ukwehliswa futhi alungiswe yi-traction transformer, efana nokugcina i-DC voltage noma i-DC yamanje yesixhumanisi esiphakathi seDC izinzile. Ngemuva kwalokho, isekhethi ye-inverter iguqula amandla aphakathi ne-DC abe amandla wezigaba ezintathu ze-AC futhi iwunikeze kumgudu wokudonswa kwe-asynchronous traction noma isigaba sesithathu sokuvumelanisa imoto. Amandla okukhipha nesivinini sesitimela kungalungiswa ngokulawula imvamisa namandla wezigaba ezintathu zamanje eziguqukayo zedivayisi ye-inverter.
  4. Idivayisi yokulungisa endaweni yokuthwebula: guqula amandla kagesi athuthwa asuka kulayini wokudlulisa amandla awenze imvamisa yamandla, imvamisa ephansi yesigaba esisodwa namandla kagesi esigaba sesithathu samandla we-AC, bese isatshalaliswa kunethiwekhi yokuxhumana ehambisanayo.
