ABSTRACT:
A circuit arrangement has a first input terminal for a first voltage potential; a second input terminal for a second voltage potential; a third input terminal for feeding a starting voltage; a first electrical connection, which provides at its first end a first output terminal for a high-pressure discharge lamp, and which is coupled at its second end to the first input terminal for the first voltage potential; a second electrical connection, which provides at its first end a second output terminal for a high-pressure discharge lamp, and which is coupled at its second end to the second input terminal for the second voltage potential; a first inductor arranged in the second electrical connection; and a starting device coupled on the input side at least to the third input terminal for feeding a starting voltage, and on the output side to one of the output terminals, and a second inductor together with a first inductor.
