    摘要： With the aid of a clocked flyback converter circuit, which can be used particularly for heating at least one filament (51) of a light source (50), such as a gas-discharge lamp, and which comprises a transformer with a primary winding (1) and a secondary winding (2), electrical energy is transferred from a primary side, which is connected to the primary winding (1) and clocked by a switch (3) as a result of said switch (3) being repeatedly activated and deactivated, to a secondary side, which is connected to the secondary winding (2), in order to heat the filament (51) that is coupled to the secondary side. After the switch has been deactivated, a voltage (V
    DS ) on the switch (3) is detected and compared to a reference value. Should the voltage (V
    DS ) on the switch (3) exceed the reference value, an error mode is activated.

    摘要： The invention relates to a push-pull converter (4) comprising a primary-side input converter circuit (44) with a plurality of primary-side switching devices (31, 32, 33, 34) in a full-bridge circuit, said input converter circuit being designed to convert an input DC voltage (42) into a first AC voltage, and comprising a transformer (39) with a primary-side winding and a ON secondary-side winding, said transformer being designed to receive the first AC voltage on the primary-side winding and to generate a second AC voltage on the secondary-side winding. The push-pull converter also comprises a secondary-side output converter circuit (45) which is designed to convert the second AC voltage into an output DC voltage (43), comprising a first semi-bridge circuit, said semi-bridge circuit comprising a first secondary-side switching device (35), a second secondary-side switching device (37), and a first center to that is connected to a first connection of the secondary-side winding. The secondary-side output converter circuit also comprises a second semi-bridge circuit which comprises a first secondary-side diode (36), a second secondary-side diode (38), and a second center tap which is connected to a second connection of the secondary-side winding, said second semi-bridge circuit not comprising a switchable component.
