ABSTRACT:
A circuit arrangement for controlling the operation of an electronic transformer (1) whose power supply can be lowered. The electronic transformer (1) is electrically connected to an output of a switch (7), and the switch (7) can be controlled by a control unit (5). A radio interference suppression circuit (8) is coupled to the switch (7) and, according to a control state, which exists on the switch (7), for controlling the starting behavior of the electronic transformer (1), the radio interference suppression circuit (8) can be disconnected from the switch (7) and/or an output (A) of the switch (7) can be short-circuited. A method for controlling the operation of an electronic transformer is also disclosed.
