Uyilo lwee-transformers ngokubanzi luxhomekeke kuphela kwi zilinganiswe isikhundla, hayi i zilinganiswe amandla, kuba ikhoyo ngoku inxulumene kuphela nomthamo olinganisiweyo. Kwi-inverter yomthombo we-voltage, ekubeni igalelo layo lamandla lisondele kwi-1, umthamo olinganisiweyo uphantse ulingane namandla alinganisiweyo. I-inverter yemvelaphi yangoku ayikho imeko. Amandla ombane wecandelo lokufaka inguqu alingana kakhulu namandla omthwalo we-asynchronous motor, ngoko ke kwimoto yomthwalo ofanayo, umthamo wayo olinganisiweyo mkhulu kunalowo we-voltage source inverter transformer.
