摘要:
A flyback converter includes input terminals and output terminals. A transformer with a first winding and a second winding are inductively coupled. A first switching element is connected in series with the first winding and a first series circuit with the first switching element, the first winding being coupled between the input terminals. A rectifier arrangement is connected in series with the second winding and a second series circuit with the rectifier arrangement, the second winding being coupled between the output terminals. The rectifier arrangement includes a second switching element. A control circuit is configured in one drive cycle to switch on the first switching element for a first time period. After the first time period the second switching element is switched on for a second time period. A third time period is determined between an end of the second time period and the time at which the transformer assumes a predetermined transformer state. The control circuit is further configured to adapt the second time period to be applied in a subsequent drive cycle dependent on the second time period applied in the one drive cycle and the third time period is determined in the one drive cycle.

A method for controlling a current between an energy source and a load is disclosed. A switching module is coupled between the energy source and the load. The switching module includes two input terminals coupled to the energy source and two output terminals coupled to the load and at least one semiconductor switching element coupled between one of the input terminals and one of the output terminals. At least one current parameter of the current is measured between the energy source and the load. The current between the energy source and the load is interrupted by switching off the switching element when the at least one current parameter reaches or exceeds at least one predetermined parameter threshold value.
