A filter circuit arrangement connects a vehicle-sided rectifier of an inductive power transfer system to a traction network of the vehicle. The filter circuit arrangement includes: rectifier-sided high voltage (HV) and low voltage (LV) terminals RTH, RTL; network-sided HV and LV terminals NTH, NTL; a vehicle ground connecting terminal VG; and a first virtual ground circuit section VGS1. An electrical connection of each of: the network-sided HV terminal to the rectifier-sided HV terminal; and the network-sided LV terminal to the rectifier-side LV terminal, includes at least one filter element (e.g. inductors L1H-L3H, L1L-L3L) of at least one filter circuit. An electrical connection of: the network-sided HV terminal to the first virtual ground section; and the network-sided LV terminal to the first virtual ground section, each includes a respective resistive element R1, R2. A further virtual ground section VGS2 may be electrical connected to the first virtual ground section, the connection including at least one resistive element BR. An electrical connection of each of: the first virtual ground section to the vehicle ground connecting terminal; and the further virtual ground section to the vehicle ground connecting terminal may include a respective capacitive element C1, C2.
