45 / 105 page  UM0324 Library functions 45/105 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+TN+ 2TS + TH + TDMA After the commutation of the Phase A low side switch, a blanking window equal to TN is applied before starting conversion of phase C, then at the end of the first conversion, it is necessary to wait a TDMA period before starting the phase B conversion. |
