Method for DC/DC conversion and DC/DC converter arrangement including four switching phases
Abstract:
A method for DC/DC conversion which comprises the steps of controlling a first switch (10) for coupling a supply terminal (5) to a first terminal (60) of an inductor (2) and a second switch (20) for coupling the first terminal (60) to a ground potential terminal (8). The method further comprises controlling a third switch (30) for coupling a second terminal (61) of the inductor (2) to the ground potential terminal (8) and a fourth switch (40) for coupling the second terminal (61) to an output terminal (6). A control sequence is used to control the four switches (10, 20, 30, 40) using four switching phases (A, B, C, D). A maximum of two switches out of the four switches (10, 20, 30, 40) change their switching position at a respective transition of subsequent switching phases (A, B, C, D).
