Claim Text:
1. A voltage setting device, comprising: a multi-step voltage output; a power converter unit having a first power section and a second power section, said first and second power sections forming a power converter branch; said second power section having a group of modules each including at least one energy storage device, a switch group, and a module output; and a control unit configured for controlling said first power section for providing a branch voltage in accordance with a first voltage step structure having voltage steps and, in at least one control mode, for controlling said group of modules for providing the branch voltage in interaction with said first power section in accordance with a second voltage step structure having voltage steps, wherein a step height of the voltage steps of the second voltage step structure is smaller than a step height of the voltage steps of the first voltage step structure.
