When the feed-forward current signa

When the feed-forward current signal is introduced, a smoothing
of the CM voltage edges is further observed, as shown in
Fig. 12. As a matter of fact, the feed-forward signal, corresponding
to the estimated current, correctly reproduces the rapid edges
of the motor CM current, thus contributing to an improved compensation
of theCMvoltage. This is illustrated in Fig. 13, where
the comparison between the estimated current and theCMmotor
current is shown.
