Abstract
An active rectifier has two control objectives: DC voltage regulation and AC current tracking. These objectives are difficult to achieve when nonlinear loads are connected to the same AC mains or voltage sags occurs. In this paper a switched PI controller to regulate the bus voltage even when voltage sag occurs is presented. Moreover, with the control law proposed, an active rectifier can works as an active filter for source current compensation. Experimental results for a 1 kVA rectifier are presented to verify the proposed control performance
