Abstract
An electrical assembly comprising power conversion system (PCM) having an output (OT), a filter device () connected to the output (OT) of the power conversion system (PCM), a pre-charging circuit (PCC), and an interface (ITF) for connecting the electrical assembly to an electrical power network (GRD). The filter device () comprises inductor system and filter capacitor system adapted to co-operate with the inductor system for filtering an alternating current. The filter device () comprises a capacitor switch device (S) for disconnecting the filter capacitor system from the inductor system. The electrical assembly comprises a grid switch device (S) connected in parallel with the pre-charging circuit (PCC). The parallel connected pre-charging circuit (PCC) and grid switch device (S) are operationally connected between the output (OT) of the power conversion system (PCM) and the interface (ITF) of the electrical assembly.
