Abstract (en)

[origin: WO2004015850A1] A dc-to-dc converter comprises a transformer (UET), which has at least one primary winding (WP) and at least one secondary winding (WS), and comprises at least one controlled primary switch (SP1, SP2) via which an input direct current voltage (UE) can be applied periodically and with a preset pulse duty factor and/or with a preset frequency to the at least one primary winding. The dc-to-dc converter also comprises at least one controlled synchronous switch (SS1, SS2), which is assigned to the at least one secondary winding and which is provided for synchronous rectification. A trigger circuit (AST) common to the primary and secondary side is provided with a digital processor (DSP) that, derived from a common clock generator (CLK), generates both the switching pulses for the at least one primary switch (SP1, SP2) as well as those for the at least one synchronous switch (SS1, SS2).
