This paper proposed three topologies of a
three phase dynamic voltage restorer (DVR), these
new topologies comprises of filtering schemes, dc-link
capacitor and three phase four wire of a three phase
transformer connection. The new Topology of the
DVR based on direct- quadrature –zero (d-q-0)
transformation technique controller is presented .The
proposed topologies of a DVR can compensate three
phase voltage swells outages. MATLAB/SIMULINK
power system toolbox is used to simulate the
proposed system. To validate the effectiveness of the
control proposed a three phase DVR prototype with a
power rating of 5KVA has been successfully
developed. Simulation and experimental results verify
the capabilities of the proposed topologies in
mitigating voltage swells in the distribution network.
