Abstract

A multi-three-phase motor drive system (100) includes a power distribution network (101), a motor drive unit (120), and a motor network (150). The power distribution network includes a partitioned direct current, DC, link (106) connected between a positive voltage rail (102) and a negative voltage rail (104). A connection between the positive voltage rail and a mid-point node (108) defines an upper portion (110) of the partitioned DC link and a connection between negative voltage rail and the mid-point node defines a lower portion (112) of the partitioned DC link. The motor drive unit includes a plurality of inverter units (122, 124, 126, 128), and the motor network includes a plurality of motor windings (152, 154, 156 158) 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.
