This paper proposes a power feedforward technique for improvement of DC link 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.
