Abstract:
A multi-three-phase motor drive system includes a power distribution network, a motor drive unit, and a motor network. The power distribution network includes a partitioned direct current (DC) link connected between a positive voltage rail and a negative voltage rail. A connection between the positive voltage rail and a mid-point node defines an upper portion of the partitioned DC link and a connection between negative voltage rail and the mid-point node defines a lower portion of the partitioned DC link. The motor drive unit includes a plurality of inverter units, and the motor network includes a plurality of motor windings which are each connected to a respective inverter unit. A first group of the inverter units is connected in parallel with the upper portion of the portioned DC link, and a second group of the inverter units is connected in parallel with the lower portion of the partitioned DC link.
