    • DC current sensor using switching-mode excited in-situ current transformer 

      Author: Grim V.; Ripka P.; Bauer J.
      (Elsevier, 2020)
      DC current component in the power grid may cause gross measurement errors and lead to overheating of power transformers. We have previously developed method how to measure DC current using fluxgate effect in existing current ...

    • Demagnetization of Current Transformers Using PWM Burden 

      Author: Bauer J.; Ripka P.; Draxler K.; Styblíková Renata
      (IEEE, 2015)
      Current transformers (CTs) show large errors when they are magnetized by dc current. This error can be reduced after proper demagnetization. One of the methods to demagnetize the CT is to increase the core flux by increasing ...

    • Different Approaches in Numerical Solution of Continuous Mathematical Models of Induction Machine 

      Author: Bauer J.; Lipčák O.; Kyncl J.
      (IEEE (Institute of Electrical and Electronics Engineers), 2018)
      Important parameters of an induction motor drives include dynamics and efficiency. Both attributes are tightly associated with accurate acquisition of hardly measurable quantities such as magnetic flux (and its position) ...
