摘要： A network filter for connecting a converter to a 3-phase supply network includes in each phase a toroidal inductor which is connected in series with a commutation inductor at a respective first connection point, and a capacitor circuit having at least four capacitances, wherein first terminals of a first, a second and a third capacitance is connected in one-to-one correspondence to a respective one of the first connection points. Second terminals of the first, second and third capacitance are connected at a common second connection point, with a fourth capacitance being connected between ground and the common second connection point. The windings of the toroidal inductors can be formed of the connecting lines which connect the corresponding first terminals to the three phases of the supply network.
