| Abstract: |
| To output a large magnetic torque with low batteries voltage for electric vehicle drive system, two modes of over modulation for space vector PWM are presented. Experimental results show that they are fit for electric vehicle drives with increasing magnetic torque and output voltage. |
| Keywords: pulse width modulation (PWM) over modulation electric vehicle |
