Measurement of Two-Level Inverter Induced Current Slopes at High Switching Frequencies for Control and Identification Algorithms of Electrical Machines

Decker, Simon; Liske, Andreas; Schweiker, Daniel; Kolb, J.; Braun, Michael

Abstract:
Several modern control and online identification algorithms for electrical machines are based on fast current slope detection. This paper shows and compares several identification methods for the inverter induced current slopes at high switching frequencies and high bandwidth of the measured signal. Test bench measurements with a SiC-MOSFET-inverter with switching frequencies up to 𝟔𝟎 𝐤𝐇𝐳 and an RL-load are used to compare the different identification methods. Best results among the investigated methods have been achieved with an easy implementable printed circuit board (PCB) design of a planar Rogowski coil.
