Abstract (EN): This paper proposes a new design method to control the currents of Single-Phase Voltage Source Converters tied to the power grid using an LCL filter. The controller is designed in the discrete domain using the polynomial technique and a resonant block to achieve a null steady-state. As the system discretization is done in the process model, the proposed approach easily deals with the time delay due to the PWM registers reload and avoids the discretization process of the controller. The intended settling time is the only parameter that the designer must select, simplifying the tuning process. The filter resonance is dealt inherently by the controller, avoiding additional damping techniques. The proposed controller is robust in the presence of a wide grid filter parameters variation. © 2020 IEEE.
