Ukwakhiwa kwama-transformers ngokuvamile kuncike kuphela ku- ilinganisiwe umthamo, hhayi ilinganisiwe amandla, ngoba yamanje yayo ihlobene kuphela nomthamo olinganiselwe. Ku-inverter yomthombo we-voltage, njengoba isici sayo samandla okufakwayo siseduze no-1, umthamo olinganiselwe ucishe ulingane namandla alinganiselwe. I-inverter yomthombo wamanje ayinjalo. Isici samandla se-transformer eseceleni yokufaka silingana kakhulu nesici samandla somthwalo we-asynchronous motor, ngakho-ke kunjini yokulayisha efanayo, umthamo wayo olinganiselwe mkhulu kunalowo we-voltage source inverter transformer.
