| Abstract |
In this paper a new digital current regulator for three phase loads is proposed. It uses polar coordinates
instead a-b co-ordinates in order to obtain a circular area for the current error trajectories.
Moreover, the voltage vector applied to the load is accurately selected in order to minimise the
switching frequency.
The robustness against both external perturbations and changes in the reference values has been
corroborated. The results of a comparative study illustrate the performance of the proposed controller
compared with other known controllers, showing a good behaviour not only in steady state but also in
transients. |
