Abstract: A converter system for electrically driving a vehicle, including a grid-side converter, a DC link with at least a first and second potential conductors, and a motor-side converter. The motor-side converter allows a bidirectional flow of energy. The grid-side converter has a single phase on the input side and is connected to a supply grid. The grid-side converter is unidirectional and allows a flow of energy from the supply grid into the DC link. The DC link connects the grid-side converter to the motor-side converter and has a first electrical energy storage between the first and second potential conductors. The electrical energy storage is connected to the DC link via an electrical connection. The flow of energy from the DC link into the further electrical energy storage and the flow of energy from the further electrical energy storage into the DC link is able to be controlled.
