Abstract

Grid converters need information about the point-of-common-coupling voltage for their control. The voltage is typically measured for current and ac-bus voltage control, and for synchronization. In order to increase reliability by decreasing dependence on this measurement, this paper proposes a multifunctional grid-voltage sensorless controller that can operate either in current- or voltage-control mode. The control system is designed to be robust against variations in grid strength, covering strong and very weak grid conditions. The controller is experimentally tested and its robustness is veriﬁed in these conditions. The results show that sensorless ac-bus voltage control can provide grid voltage support.
