Hello,
I am using a custom made inverter with the F28069 Piccolo series microcontroller.
As far as I know, everywhere I have looked at I have seen that in order to use overmodulation, current reconstruction is needed. Nevertheless, I wonder that if I use hall sensors to measure the phase current of the motor directly, there is not going to be any problem with the sensor not been able to measure the current properly as it would happen using shunt sensors in the legs of the inverter. Therefore I guess I do not have to use the current reconstruction algorithm.
In such case I guess that the only thing I would have to change in the code to allow for overmodulation is to increase the variable USER_MAX_VS_MAG_PU over 1.0. Isn't it?
Thanks
Javier
