摘要: In this paper, four different system topologies for dynamic voltage restorers (DVRs) are analyzed and tested, with particular focus on the methods used to acquire necessary energy during a sag. Comparisons made between two that can be realized minimum amount of storage, taken from grid sag, take stored devices Experimental tests using 10-kVA DVR show no-energy storage concept is feasible, but an improved performance achieved certain sags topologies. The results comparison rank no-storage topology passive shunt converter load side first, followed by constant dc-link voltage.
