Abstract:
A power converter for an electric power system comprises a switching circuit ( 102 ) for supplying, in a first operating mode of the power converter, voltages for driving a rotating electric machine. The power converter comprises a contactor system ( 110 ) and a controller ( 109 ) for using, in a second operating mode of the power converter, the switching circuit and at least one of windings ( 115 ) of the rotating electric machine as a voltage-decreasing direct voltage converter between direct voltage terminals of the power converter. Therefore, the switching circuit of the power converter can be utilized both for driving the rotating electric machine and, for example, for charging a battery element connected to a direct voltage terminal of the power converter.

Claim (Index 11):
A method for controlling an electric power system that comprises:\n a rotating electric machine having one or more windings, and a power converter comprising a switching circuit having direct voltage rails, a first direct voltage terminal for connecting the direct voltage rails to first direct voltage, a second direct voltage terminal for connecting the direct voltage rails to second direct voltage, a supply voltage terminal connected to the windings of the rotating electric machine, first controllable switches between a first one of the direct voltage rails and the supply voltage terminal, and second controllable switches between a second one of the direct voltage rails and the supply voltage terminal, the method comprising, in a first operating mode of the electric power system, controlling the power converter to drive the rotating electric machine, characterized in that the method comprises in a second operating mode of the electric power system:\n controlling a contactor system to disconnect a pole of the second direct voltage terminal from the first one of the direct voltage rails and to connect the pole of the second direct voltage terminal to at least one of the windings of the rotating electric machine, and \n controlling one or more of the first controllable switches to alternate between conductive and non-conductive states so as to operate the switching circuit and the at least one of the windings of the rotating electric machine as a voltage-decreasing direct voltage converter between the first and second direct voltage terminals.
