Voltage tolerance testing of three-phase voltage source converters
Artikel i vetenskaplig tidskrift, 2005
This paper proposes a protocol for testing the immunity of three-phase self-commutated converters to voltage dips. An overview of voltage dips due to short circuits and earth faults that may affect a converter is given and their effect on the converter is demonstrated through simulation. Results confirm that the existing standard protocol given in IEC 61000-4-11 is not complete. An extended testing protocol is therefore proposed, which is compatible with IEC 61000-4-11.
