ABSTRACT: The inventiuon relates to a matching circuit arrangement for operating a high-pressure discharge lamp, this circuit arrangement being provided with two input terminals for connection to a supply source, each of which is connected to a respective output terminal, these output terminals being intended for connection of the high-pressure discharge lamp, a controlled semiconductor switching element having a thyristor characteristic being included in a connection between an input terminal and a respective output terminal. A control electrode of the switching element is connected to a main electrode of a further controlled semiconductor switching element having a thyristor characteristic. The main electrode of the switching element is connected together with the main electrode of the further switching element to the input terminal. The main electrode of the switching element is connected to the output terminal. The control electrode of the further switching element switch is connected to a voltage divider circuit between the input terminals. In this configuration, during operation of the lamp, the lamp current will flow substantially solely via the switching element and the housing thereof can be directly contacting the input terminal, which is favourable for a satisfactory cooling of the switching element.
