ABSTRACT:
A bridge circuit arrangement for the operation of discharge lamps comprises a direct voltage source-supplied inverter (2) whose terminals {8,9) are connected to the series circuit of an inductor (10) and a discharge lamp (11}. By means of the symmetrical arrangement of the capacitor (14) with regard to the branches of the bridge circuit, the asymmetrical pulse load on the operating voltage is minimized and the grid filter {1) can have a simpler design. This allows economical manufacture of the discharge lamp with electronic ballast.
