Abstract

Parallel operation of power converters provides a promising solution for the integration of distributed generations. To properly share the load power among different converters, the master-slave control architecture has been widely adopted in the literature. In this paper, it is revealed that the interactions among the master converter and the slave converters will cause instability under certain conditions. To properly explain the mechanism and address this problem, an explicit frequency-domain stability analysis of the parallel-converter system is presented in this paper, which would provide valuable guidance for the converter controller design. Finally, simulation results of a parallel-converter system with master-slave configuration are presented for verification.
