Abstract
This paper presents a simple control
strategy that is employed together with an optimization
methodology to achieve optimal efficiency in systems
composed by multiple parallel converters. An external
loop is responsible for regulating the dc bus voltage
and providing a current reference that is weighted in
function of the power processed by the system, and then
generating optimal current references for each converter.
This enable the system to operate with optimal efficiency
for all its load range. Experimental results demonstrate th
e
superior performance of the proposed strategy, improving
the efficiency of the system in almost
10
% under light load
operation in comparison with the conventional strategy of
equal power sharing among converters
