Abstract
The teachings herein include DC/DC converter systems. An example system may include: a full-bridge converter and a switch control circuit. The converter includes a primary side and a secondary side full-bridge circuit and a transformer. AC nodes of the primary side are connected to a primary side of the transformer and AC nodes of the secondary side to a secondary side of the transformer. The switch control circuit: controls the primary side and the secondary side circuits in a normal operating phase including modulation of an input voltage by the primary side full-bridge circuit transferring power via the transformer, control the primary side and the secondary side in a free-wheeling phase during which they are both deactivated to reduce the transformer's magnetization current; and control the full-bridge circuits to switch between the normal operating phase and the free-wheeling phase alternately.
