GALVANICALLY ISOLATED DC/DC CONVERTER AND METHOD OF CONTROLLING A GALVANICALLY ISOLATED DC/DC CONVERTER

摘要

A galvanically isolated DC/DC converter (2) comprises at least one first side converter circuit (20) coupled between a pair of first side DC terminals (10), the first side converter circuit (20) having at least a first and a second switching element (20a, 20b), with each of the first and second switching elements (20a, 20b) comprising a switch (22, 24) and a diode (23, 25) connected in parallel, and at least one second side converter circuit (40) coupled between a pair of second side DC terminals (60), wherein, when the DC/DC converter (2) is in power transfer operation from the pair of second side DC terminals (60) to the pair of first side DC terminals (10), the second side converter circuit (40) is adapted to alternate between two power transfer states, wherein a conductive state of the diode of one of the first and second switching elements (20a, 20b) is the result of one of the two power transfer states, with the first side converter circuit (20) being controlled such that the switch of the respectively other of the first and second switching elements (20a, 20b) is closed for an adaptation interval (T_P) prior to a beginning of the one of the two power transfer states.
