Abstract:
A dual active bridge (DAB) converter operates in a power conversion operation by controlling multiple bridge configured switches to charge a magnetization inductance from an input supply during a charge phase of a power cycle and to discharge the magnetization inductance into an output of the DAB during a discharge phase of the power cycle. The DAB converter includes an input converter connected to the input supply, an inductance connected to the input converter, a transformer comprising a primary and a secondary winding, and an output converter connected to the transformer. The input and output converters each include a first pair of switches forming a first circuit path, and a second pair of switches forming a second circuit path parallel to the first circuit path. The first and second circuit paths are both completed by a third circuit path including the inductance and the primary winding of the transformer.
