  Modular battery integrated converters or so called dynamically reconfigurable
battery packs are expanding into emerging applications, including
electromobility and grid storage. Although they offer many degrees of freedom,
the state of the art focuses on single output systems and mostly neglects
potential of such systems in generating multiple controlled outputs. This paper
investigates the use of the extra degrees of freedom that a reconfigurable
battery offers to generate multiple outputs for the adjustable supply of
various independent loads. The technology offers the potential for functional
integration, exploiting already existing transistors, and for a reduction of
separate dedicated power conversion stages. Interleaved output ports, where
some modules are shared among different outputs, can further reduce the
necessary power electronics and cost. However, using conventional modulation
techniques in particular phase-shifted carrier modulation can be challenging
with shared modules among multiple ports, and different control objectives can
adversely impact the overall performance. Therefore, this paper proposes a
strategy to decouple the control of multiple ports to enable further
simplification of required power electronics. The proposed system does not
require any additional active switches for the isolated port and can operate
with a wide range of output voltages. Simulation and experiments verify the
developed analysis.
