Method and switching assembly for stabilising electric current in an intermediate circuit

摘要

The method involves connecting electrical energy storage devices (46,52) to intermediate circuit (16) via respective controllable switching unit (42,48). Control units (44,50) determine respective voltage signal (U1,U2) fed into the intermediate circuit, and generate respective control signal (S1,S2) dependence on determined voltage signal so that power exchange between the intermediate circuit and electrical energy storage device is controlled. An independent claim is included for a circuit device for stabilizing voltage signal fed into intermediate circuit.
