Hello,
I am using V/F Control to Operate Three Phase induction motor for EV Application. I am using SPWM Technique to give gate pulses to VSI. I have connected 72 V Battery and my Induction motor is also 72V Three phase. In this attached project, I was trying to do the same but after 15Hz frequency, one leg of of inverter switches off and then motor will not rotate properly. I have checked PWM Gate pulses. I have attached Screenshot of that. I am bit confused that my PWM Pulses are not correct. and one more thing current of each leg are different. Please Help.
