14 Operation principle and hardware description
Operation principle
The DC/DC converter unit (DDC) transfers energy from a common DC bus of a drive into
an external energy storage and discharges energy back to the DC bus. The energy
storage can be, for example, a battery or super capacitor. The energy storage media does
not belong to the converter unit delivery.
The DC/DC converter unit has a single converter module or parallel converter modules
under the command of one BCU control unit. Parallel DC/DC converter modules must
have a common energy storage. Each parallel module must have the output cabling of its
own. We also recommend that you use identical cablings (cable type, cross-sectional
area, and length) and have identical load for each module. For other solutions, contact
ABB.
Typically, the DC/DC converter is used in marine applications for heave compensation,
peak load compensation, propulsion supply in harbors, energy storage instead of an
additional generator and so on. The DC/DC converter can also be used in automotive
applications such as battery simulators for test benches and electric car charging systems
and also in several other applications where energy storage and reuse is needed.
