Dear Friends

I have been asked to design an inverter for a 150kW brushless motor for a (commercial) electric vehicle.

The batteries can supply 320-400 Vdc and the motor performance characteristics are included in the attachment. Maximum DC link current before the inverter is 400A. I have been asked to consider playing with V-I characteristics to be able to increase the 1 minute rating to 700Nm.

Please help....

Also how do I size my IGBT's. will 600V ones be enough?

 

Your requirements are just a tad bit beyond the scope of these forums.

AAC is primarily oriented towards budding electronic hobbyists/enthusiasts.

I suggest that you subscribe to IEEE.org, and peruse their articles.
