Greetings. I am trying to find some motor control reference designs with the aim of getting to a custom VFD design for a dynamometer that will be powered by an AC 3-phase induction motor, upto a level of about 40kW. There is a bewildering array of reference designs and development boards just on the TI website - InstaSPIN, DesgnDrive, Stellaris, etc. that go upto about a kW. Would it be a good idea to choose one of these and scale it up to 40kW by changing the power module and possibly parallelizing the output as has been done for the low-voltage 5kW Forklift traction motor design? Apart from using optoisolators and upgrading the power modules what else would I need to take care of for functional completeness (safety and EMI issues apart)?
I know this is pretty vague at the moment so I am not asking for too much detail. Any broad pointers to help sharpen my focus would be greatly appreciated. Thanks very much!
Best - Ram
