Abstract
In some examples, a circuit includes a first power converter cell and a second power converter cell. The first power converter cell has a first bidirectional interface. The first power converter cell is configured to switch power from the first bidirectional interface to a second bidirectional interface in a first operation mode. The second power converter cell has a third bidirectional interface. The second power converter cell is configured to switch power from the third bidirectional interface to the second bidirectional interface in the first operation mode in parallel with the first power converter cell.
