Current Sharing
5–2
TM-XDOP-01XN
Overview
In many applications multiple power supplies are connected in parallel to supply
large currents to a load. Typically, because of differences in the load wiring and
supply setpoints, each power supply will provide different amounts of current to
the load. Each of the supplies may have to be controlled separately and output
transient response may not be optimal.
6kW and 12kW power supplies equipped with the optional CANbus interface can
be configured to current share using a simple daisy chain control connection
between the units. When configured for current sharing, one supply, configured as
a master, controls the remaining supplies (slaves), via CANbus to equalize the
current drawn from each unit. In addition to balancing the supply outputs, the
current share configuration allows you to control the output voltage, current limit,
and output enable/disable function of all the supplies through the master supply.
You can also choose direct display and readback of the total current from the
system.
Current sharing can be used with a maximum of five supplies of the same model.
Figure 5-1 shows a typical current share system setup.
