The aim of the study is to design a Dynamic Voltage Restorer (DVR) with size minimized transformer. Transformer is the back bone and of vital importance in the power quality conditioners. However its cost is much higher than the other components of power system due to size of its core and windings. Overall cost can be reduced if we reduce these parameters. Transformer size is inversely proportional to the frequency of operation and flux density. Hence the reduction in the volume and the weight can be obtained by high frequency operation of the magnetic core. This study proposed a novel design of a power electronic circuit, which converts the low level frequency to high level at the primary of the transformer to minimize its size. At secondary side, a frequency is restored to 50 Hz and achieve the compensation. By using MATLAB SIMULINK based simulation results shows the proposed system decreases the transformer size with same power of transformer and capable to control the voltage sag and swell in efficient manner.
Key words: Dynamic voltage restorer, flux density, high frequency transformer, , , ,
