    Low frequency conducted disturbances are usually induced by AC arc furnaces supplies: harmonic currents and flicker. That is why modern installations use a DC supply, less pollutant and sparing of electrodes. However, this process is not sufficient to reduce flicker during the melting sequence. On the basis of this problem, a structure of a modified bridge rectifier operating in a natural switchin... View full abstract»
