Title

POWER CONTROLLABILITY OF A THREE-PHASE CONVERTER WITH AN UNBALANCED AC SOURCE

Authors

Abstract

Three-phase dc–ac power converters suffer from power oscillation and over current problems in case of the unbalanced ac source voltage that can be caused by grid/generator faults. Existing solutions to handle these problems are properly selecting and controlling the positive- and negative-sequence currents. In this paper, a new series of control strategies which utilize the zero sequence components are proposed to enhance the power control ability under this adverse condition. It is concluded that by introducing proper zero-sequence current controls and corresponding circuit configurations, the power converter can enable more flexible control targets, achieving better performances in the delivered power and the load current when suffering from the unbalanced ac voltage.

Key Words

Control strategy, dc–ac converter, fault tolerance, unbalanced ac source.
