Why do inverter of a motor need capacitor? More specifically, a Tesla model 3 induction motor case. But in fact, almost all electrical vehicle's motor has film capacitor. Film capacitor is an important part at inverter, IGBT, or SiC mosfet module. But, why does a inverter of a EV motor needs capacitor?
Is it used to correct power factor? We know for sure that motor coil is inductance. It causes phase lag and power loses. Does the capacitor compensate it?
Also, I googled. Single phase induction motor has a start and a run capacitor. Tesla model 3 is with a 3 phase induction motor. Does it means that it will has 3 run and start capicitor?
Sorry I am new at electrical parts. Please correct me.
Thank you very much!
