dc.description.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
