A voltage setting device has at least one multi-step voltage output, at least one power converter unit, which has at least one first power element that forms at least a part of a power converter branch, and a control unit that controls the first power element according to a first voltage step structure to provide a branch voltage. The power converter unit includes at least one second power element that, together with the first power element, forms the power converter branch and includes a group of modules, each with at least one energy storage device, a switch group and a module output. In a given control mode the control unit controls the group of modules to provide the branch voltage in cooperation with the first power element according to a second voltage step structure which is more detailed than the first voltage step structure.
