Voltage dip immunity of converter-connected distributed generation units will become increasingly important. This paper focusses on the relation between the voltage-dip ride-through capability of converters and their current-control strategy. A comparison is made between a recently proposed control strategy with programmable damping resistance and the classical sinewave control algorithm. The first-mentioned control structure will prove to yield an improved voltage dip immunity. Experimental tests on a single-phase full-bridge bidirectional converter are carried out and validate the aforementioned postulations. (c) 2007 Elsevier Ltd. All rights reserved.
