Abstract
According to one aspect of the present disclosure, there is provided an apparatus that includes a first power converter stage connected to a first side of a first transformer, and a second power converter stage connected to a first side of a second transformer. The apparatus further includes an interleaved multi-bridge circuit connected to the second side of the first transformer and to the second side of the second transformer. The apparatus further includes a controller that is configured to operate the interleaved multi-bridge circuit in a parallel mode in which the second sides of the first and second transformers are in parallel at a DC terminal of the interleaved multi-bridge circuit and in a series mode in which the second sides of the first and second transformers are in series at the DC terminal.
