Abstract
A bidirectional composite converter is provided. The bidirectional composite converter can be used with power electronics, such as but not limited to electric vehicles and other applications. In some implementations, for example, the composite converter may be used in a powertrain of an electric vehicle to couple batteries to a high voltage bus of the vehicle to provide power to the motors and to one or more integrated charging ports (e.g., ac grid wired connections or a wireless charging port) for extremely fast charging. In various implementations, the bidirectional converter architecture may comprise one or more dc transformer modules (DCX's) arranged with output port(s) coupled in series at an output port of the composite converter.
