摘要

The circuit (10) has a circuit path (11) and another circuit path (12), a switch (17), and an electric machine (13) e.g. compressor, that is supplied with charging current from a battery (14) of a vehicle i.e. electric car, via the former circuit path. The battery supplying the electric machine is charged by an external power supply (15) via the latter circuit path. The switch is provided between the former circuit path and the latter circuit path. A mesh filter (23) is arranged in the latter circuit path. A coil (24) is arranged in the mesh filter.
