Abstract:
A motor drive device can include: a control circuit configured to adjust each phase current of a three-phase inverter of a motor; where the phase current of the three-phase inverter rises from zero to a first threshold during a first time interval; and where the phase current is controlled to drop gradually from the first threshold to zero during a second time interval in order to increase the second time interval.
