<p>An arrangement in connection with an electric drive system, the electric drive system comprising an intermediate circuit (DC), with two or more supply units (S.1-S .n ) and two or more inverter units (I.1-I .n ) connected thereto, and an electric machine (G) having two or more three-phase windings galvanically separated from each other. Two or more inverter units (I.1-I .n ) are connected to the three-phase windings. The arrangement further comprises first main circuit switches (X11.1-X11 .n ) to galvanically separate each supply unit (S.1-S .n ) from a supply, second main circuit switches (X12.1-X12 .n ) to galvanically separate each supply unit (S.1-S .n ) from the intermediate circuit (DC), first intermediate circuit switches (X21.1-X21 .n ) to galvanically separate each inverter unit (I.1-I .n ) from the intermediate circuit (DC), and second intermediate circuit switches (X22.1-X22 .n ) to galvanically separate each inverter unit (I.1-I. n) from the electric machine (G).</p> |
