Abstract:
|
This paper proposes a new methodology for
efficiency optimization in systems composed by parallel
converters. The proposed methodology takes into account
the individual efficiency curves and determines the
optimum operating point for each converter such that
the maximum efficiency of the arrangement is achieved
for the entire load range. Due to the nonlinearity of the
problem and the complexity of the solution hyperplane,
the optimization process is divided into stages of global
optimization, local optimization and ambiguity resolutio
n.
This latter verifies the existence of multiple global
minima and selects the most appropriate in function of
previous power distributions. Case studies demonstrates
the validity of the proposed methodology for different
systems configurations. |
