用于驱动电灯的电路装置
摘要：
本发明涉及一种驱动电灯(5)、特别是介电势垒放电灯的电路装置，该电路装置具有一个设计为使电压升高的变换器的输入级(1)、特别是升压变换器，并且具有至少一个接在后面的其它电路级(2)、例如一个作为脉冲级的反向变换器。在升压变换器(1)和反向变换器(2)之间连接一个中间电路过流保护机构(3)，该保护机构在故障情况下、也就是说尤其是在输入过流保护机构(1)没有响应时，所述中间电路过流保护机构保护反向变换器(2)。
摘要（英）：

A circuit arrangement for operating electric lamps (5), in particular dielectric barrier discharge lamps, has an input stage (1) in the form of a voltage-increasing converter, in particular a step-up converter, and at least one subsequent further circuit stage (2), for example a flyback converter in the form of a pulse stage. An intermediate circuit overcurrent protection device (3) is connected between the step-up converter (1) and the flyback converter (2) and protects the flyback converter (2) in the event of a fault, specifically in particular if the input overcurrent protection device (1) does not respond.
