Abstract

This paper examines the control of unbalanced three-phase three-wire power electronic systems. The control strategy proposed is derived from a double controller scheme that employs one controller for the positive sequence and another for the negative sequence. The controller is implemented in a microcomputer-based system at the stationary reference frame. The simulation and experimental results demonstrate the validity of the proposed methodology
