Abstract (en)
[origin: WO2009135736A1] The invention relates to a circuitry for feeding a drive machine having a plurality of, preferably two, winding systems, particularly rotary current winding systems, wherein each winding system is associated with a dedicated converter, preferably a pulse width-modulated rotary current converter having a voltage intermediate circuit and an upstream diode rectifier, wherein at least one converter can be connected on the input side to different, non-synchronized power grids.
