- Alternative Abstract
- This paper proposes a power feedforward technique for improvement of DClink Voltage Control Performance in the Dynamic Voltage Restorer. The DC-link Voltage is able to be unstable for an instant if there is any change in the load or voltage sag. This phenomenon affects the voltage of inverter which is compensating for the voltage sags or swells. By including output power feedforward component of the inverter in the DC-link controller, the DC-link voltage can settle down quickly. The proposed technique was validated through the simulation and experimental results.
