<p>The invention relates to a circuit arrangement for operating a discharge lamp (1) by means of a direct voltage source, which circuit arrangement is provided with - direct voltage terminals (A,B) for connection of the direct voltage source, - alternating voltage output terminals (K,L) for connection of the discharge lamp, - a direct voltage/alternating voltage converter (3), and - a current limiter (5) for limiting the current through the lamp during the operating condition. According to the invention, the direct voltage/alternating voltage converter (3) is a sine converter and a controllable direct voltage converter (2) is arranged between the sine converter and the direct voltage input terminals (A,B).</p> |
