Abstract: Sudden variations of voltage can be damaging for voltage-sensitive loads. Dynamic voltage restorer (DVR), which is a power-electronic converter-based device, is an economical solution for voltage variations compensation. In this paper, a high-frequency (HF) transformer-based DVR is designed for household applications. As the household application is considered, the DVR will be low-power and it should be designed to be compact and economic. Therefore, the HF transformer is used in the design in order the system to be more compact and economic. Also, unlike other HF transformer-based DVR structures, no energy storage is used and the number of active converter stages is minimised. The topology selection and compensation capacity are justified in the paper. The simulation results of the designed DVR are presented to verify its performance.
