To analyze AC copper loss of the electric vehicle (EV) motors accurately, it is calculated using the finite element method (FEM) after extracting the inverter-fed current (IFC) by space vector PWM. However, the harmonic waves of the IFC are different at each operating point, it takes a long time to...
