Originální abstrakt

This paper is focused on analyzing and compensating the dead-time effects in the vector-controlled AC system. The use of dead-time in power electronics drive systems to prevent a short circuit in the DC link is necessary. However, dead-time effects can lead to distortion output voltage of VSI and ripple of phase currents. It is used a feed-forward approach for the standard compensation and a feedback loop with adaptive harmonic compensator to suppress the persistent sixth harmonic components in dq-currents. This proposed approach is validated by simulation and real experiment.
