This paper is concerned with a pre–flicker compensation strategy adopted by a dynamic voltage restorer (DVR) to mitigate voltage flicker in a power system. The DVR configuration based on flying capacitor multicell (FCM) converter is proposed to mitigate the voltage flicker because of taking the FCM converter advantages such as transformer–less operation and natural self–balancing of flying capacitors voltages. The proposed DVR consists of a series converter on the source–side and a shunt rectifier on the load–side. Choosing this configuration for DVR makes it possible that the shunt rectifier can maintain dc link voltage at a desired value which results in the proper performance of the DVR. Furthermore, the DVR reference voltages calculation method and also, the pre–flicker compensation strategy, which are based on synchronous reference frame (SRF), are adopted as the control strategy. Simulation results, which are provided by PSCAD\EMTDC software, verify that the proposed detection and determination methods are able to detect the voltage flickers and determine the three single–phase reference voltages of DVR as fast as the DVR mitigates the voltage flickers.<\div>
