Enhancement of the DC Bus Voltage Control of a Shunt Active Power Filter Through Rooted Tree Optimization

Resumo

Simulation results outcomes verify the proposed system's efficiency RTO. The PI controller is employed extensively in this work for controlling the DC-link voltage. Was used the anti-windup controller in this paper may not perform satisfactorily for fast changing load conditions in relation to overshoot, settling delay and undershoot. The DPC of shunt active power filter (SAPF) three phase is a successful approach to guarantee both stability and good performance for the DC link voltage. A new technique is offered in this work enhance the regulation of the DC link voltage using the DPC method. In order to illustrate the performance improvement, the root tree optimization (RTO) is employed to obtain optimal gains value for the windup prevention controller.
