Abstract

The present disclosure relates to a dual active bridge DC-DC converter comprising a low voltage port; a high voltage port; a set of n transformers, each transformer comprising a primary and a secondary winding magnetically coupled to each other; a single active high voltage bridge circuit connected between the high voltage port and the set of n transformers, wherein the n transformers are arranged to operate in series; n low voltage active bridge circuits connected in parallel between the set of n transformers and the low voltage port, wherein the n transformers are arranged to operate in parallel; a control unit configured to control: a first phase-shift angle between one of the n low voltage active bridge circuits and the single active high voltage bridge circuit; and a second phase-shift angle between the n low voltage active bridge circuits, thereby extending an operation range of the dual active bridge DC-DC converter; wherein n is a positive integer number larger than or equal to 2.
