Operation analysis and new current control of parallel connected dual converter system without interphase reactors

Abstract

In this paper, a predictive current control scheme for a twelve-pulse parallel connected dual power converter system without interphase reactors (IPR) is presented. Firstly, the characteristics of system without IPR are analyzed and compared with that of system with IPR. And the predictive current control of this system is discussed. Finally the validity of the presented system and the excellence of the predictive current control response is proved through the simulation results and experimental results.
