Abstract
A system controller for a motor drive system comprising a phase current reconstructor configured to perform operations. The operations comprise receiving a stator current angle and a plurality of phase current sense signals from a plurality of respective devices that in operation drive the motor drive system, selecting, based on the received stator current angle, a reference table from among a plurality of reference tables that store reconstruction scaling factors for respective phase currents, obtaining, from the selected reference table, respective reconstruction scaling factors for the respective phase currents, generating, from the obtained reconstruction scaling factors, respective reconstructed phase current magnitude values for the plurality of devices, and outputting the reconstructed phase current magnitude values.
