2.9 System configuration

Figure 2-20 shows a typical common DC bus drive system.
The rectifier module converts AC voltage to DC voltage, and the DC voltage is distributed to all inverter
modules through the DC bus, then the inverter modules convert the DC voltage to AC voltage to drive the
motor to rotate. An external DC fuse is required for the connection between each inverter module and DC
bus.
