| 摘要 |
The invention relates to a voltage setting device, comprising at least one multi-step voltage output (34), at least one power converter unit (30), which has at least one first power element (46) that forms at least a part of a power converter branch (32), and a control unit (44), which controls the first power element (46) according to a first voltage step structure (S1) such as to provide a branch voltage (Uz). In order to provide a voltage setting device of the type in question in which non-uniform output voltage steps can be generated in a particularly simple manner in terms of design, according to the invention the power converter unit (30) comprises at least one second power element (48) that, together with the first power element (46), forms the power converter branch (32) and comprises a group of modules (36.x), each comprising at least one energy store (38), a switch group (VB) and a module output (40), and in at least one control mode the control unit (44) is intended to control at least the group of modules (36.x) such as to provide the branch voltage (Uz) in cooperation with the first power element (46) according to a second voltage step structure (S2) which is more detailed than the first voltage step structure (S1). |
