Transformerless rail interties are of high interest for the interconnection of the European 15kV/16.7Hz rail supply with the 50Hz industrial grid due to the direct connection to the rail supply without a 16.7Hz transformer. The MMLC is an emerging topology which offers high blocking voltages, high modularity and very high power quality. Two transformerless interties are presented and compared which...
The productivity of AC electric arc smelters widely used in the nonferrous metals industry is related to the arc voltage. Attempts to improve productivity with longer arcs and higher arc voltages give rise to power fluctuations which cause voltage flicker and frequent arc reignition failures. The furnace power is commonly regulated by moving the electrode rods to adjust the arc length. A 100 MW AC...
