| 摘要 |
The invention relates to a DC-DC converter with a first input voltage connection and a second input voltage connection, between which an input DC voltage can be applied, a first converter device, which is designed to convert a first sub-voltage of the input DC voltage into an output DC voltage, and a second convertor device, which is coupled between the first input voltage connection and the second input voltage connection in a series circuit relative to the first convertor device on the input side and which is designed to convert a second sub-voltage of the input DC voltage into an output DC voltage. The DC-DC converter further comprises a control device which is coupled to the first convertor device and the second converter device and which is designed to operate the first converter device with a variable first sub-voltage and the second converter device with a constant second sub-voltage. |
