  • Method for controlling a full-bridge DC-dc converter
    Patent number: 9906148
    Abstract: In order to enable a switching process with a zero-voltage sequence (ZVS) in a full bridge DC/DC converter (1) with phase shift control without having to provide an additional inductor for this purpose, it is provided that a short-circuit is generated in the secondary-side output rectifier (5) in the transition phase from the active to the passive phase prior to switching to a passive phase of the full bridge (2), said short-cut increasing the primary current (ip) across the primary side of the transformer (T) by means of the resulting short-circuit current (ik) across the secondary side of the transformer.
    Type: Grant
