Hi,
I am trying to understand the difference between the Vd and Vq created by the current controller output and the actual calculation of Vd and Vq done by dq transformation of Vabc voltages.
The line voltages are PWM voltages. So if I directly find Vd and Vq I get very bad waveforms. If I filter the PWM voltages to get the fundamental waveform and then find Vd and Vq, they do not match with the Vd and Vq generated by the current controller output. What could be the reason? I believe they both should be the same.
