Figure 24. Low side switches gate signals (low modulation indexes)
Note that these current feedbacks are constant in the view in Figure 25 because it is
assumed that commutations on Phase B and C have occurred out of the visualized time
window.
Moreover, it can be observed that in this case the two stator current sampling conversions
can be performed between the two commutations of the Phase A low side switch, as shown
in Figure 25.
Figure 25. Low side Phase A duty cycle > DT+T_N+ 2T_S + T_H + T_DMA
After the commutation of the Phase A low side switch, a blanking window equal to T_N is
applied before starting conversion of phase C, then at the end of the first conversion, it is
necessary to wait a T_DMA period before starting the phase B conversion.
