AN2531 - Motorola

AN2531 Standard Space Vector Modulation

svmStdDtXor_sync channels, svmStdDtXor_res channels and svmStdDtXor_fault channel, if used. 5. Enables servicing by assigning a high, middle or low priority to the channel priority bits. All svmStdDtXor_R and svmStdDtXor_T channels must be assigned the same priority to ensure correct operation. The CPU must ensure that the svmStdDtXor_sync or svmStdDtXor_re.

AN2531/D The dead-time correction technique requires knowledge of the instantaneous direction of phase currents. In the case of positive phase current the top channel high-time is equal to the calculated high-time and the bottom channel has to control the dead-time. In case of negative phase current the bottom channel low-time is equal to the calcul.
