The invention relates to a circuit arrangement for the charging of vehicle batteries (1) in a vehicle. The circuit arrangement comprises a first inverter (I1) mounted downstream of the vehicle batteries (1), to which first windings (U1, V1, W1) of an electric drive motor are connected and which can be connected to a DC network for the charging operation of the vehicle batteries. Furthermore, a second inverter (I2) is provided and mounted downstream of the vehicle batteries, to which second windings (U2, V2, W2) of the electric drive motor are connected. According to the invention, the first (U1, V1, W1) and second windings (U2, V2, W2) have a common star point which is formed in the closed state by a switch (S) and which can be separated for the charging operation by opening the switch (S). In this way, the first (U1, V1, W1) and second windings (U2, V2, W2) together form a DC throttle for damping harmonics. |
