In this paper, a high-performance 22 MW/27 MVA test bench using a pumpback topology is introduced for testing electrical machines. It proposes a cost-effective concept that works reliably even with a weak grid. A paralleling concept of two three-level integrated gate-commutated thyristor (IGCT) converters is presented. I generates a five-level pulse pattern with low harmonic distortion at 600-Hz carrier...
In this paper, a high-performance 22 MW/27 MVA machine test bench using pumpback topology is introduced. It proposes a cost-effective concept that works reliably even with a weak grid. A paralleling concept of two three-level IGCT converters is presented. It generates a five-level pulse pattern with low harmonic distortion at 600 Hz carrier frequency and 80 Hz load frequency. The selected magnetic...
