I asked question and got two answers as below.

But I think that these answers are different.

- Real DC bus voltage : 300V

- Maximum voltage of ADC sampling : 400V

If Vd/Vq from PI is _IQ(0.5),

In the first answer, real Vq/Vd = _IQ(0.5)*_IQ(300/400)*_IQN(400/sqrt(3)) = _IQ(0.5)*_IQN(300/sqrt(3))

In the second answer, real Vq/Vd = _IQ(0.5)*Real DC bus voltage = _IQ(0.5)*_IQN(300)

What is the correct answer?

Please be noted, the real voltage of Vd/Vq from PI output is related to SVPWM mode and the maximum output of PI. For controlSUITE, the real Vq/Vd is the output of PI*Real DC bus voltage.
