摘要

A method of operating a bidirectional push - pull type flux converter having an input stage (2) for converting a first DC voltage (U) into a first AC voltage (U), a transformer (5) having at least one primary winding (3) and at least one secondary winding (4) A first AC voltage in a second AC voltage (U) and an output stage (6) for converting the second AC voltage (U) into a second DC voltage (U) wherein a control device (13) is constructed such that for the operation of the push-pull flow converter (1) in each case two Semiconductor switching element pairs (S1, S4; S2, S3 and S5, S8, S6, S7) are alternately switched on and off by two H-jumpers (12, 15) by means of the control device (13), so that the transformer (5) during a first time interval (T1) in a first direction and during the second time interval (T2 = T1) corresponding to the duration of the first time interval in the opposite direction is flooded and at the output of the second H-switching bridge (15) results in a pulse-modulated DC voltage (U) and wherein during a Umschaltzeitintervalls tdie semiconductor switching element pairs of the two H-switching bridges (12, 15) are switched such that a short circuit is generated, the power generated by the controller during the switching time interval is controlled by adjusting the switching time interval, and a push-pull type flux converter and an arrangement with this push-pull type flux converter.
