A filter for a power converter provided in-line with at least one live line of a power network. The filter has an input section with an input inductance provided at an input of the power converter and an output section with an output inductance provided at an output of the power converter. A neutral inductance provided between the power converter and a neutral line of the power network such that the neutral inductance is not in-line with the neutral line of the power network. The neutral inductance is shared by the input section and the output section.
