Controlling the operation of an converter having a plurality of semiconductor switches for converting high power electric signals from DC to AC or from AC to DC

摘要

Method and computer program for controlling the operation of a power converter (100) comprising a plurality of semiconductor switches (S 1 , S 2 ). The method comprises determining, in a rotating dq-reference frame, a direct current error signal (i derr ) and a quadrature current error signal (i qerr ). Cross-coupling between the direct and quadrature axis improves stability and allows for reduced perturbation.
