Abstract: A ballast for a discharge lamp (L) contains, in the normal manner, an invertor (C) supplied from a DC voltage source (B), which invertor generates the alternating voltage for the discharge lamp (L). The discharge lamp (L) is located in parallel with the capacitor (C10) of a series-resonant circuit (L6/C10). A variable frequency AC voltage is supplied from a variable frequency generator (6, 7, 8, 9, 15, 16) to the invertor (C). The frequency of the variable frequency generator can be controlled by a control unit (10). Control signals are supplied to the control unit, which signals correspond to various parameters of the ballast. These parameters are the lamp voltage, the lamp current, the DC power, the DC voltage, a low-voltage DC voltage and the phase angle of the load circuit (E) for the invertor (C). The reaction of the control unit (10) to changes in the parameters mentioned is to change the frequency of the frequency generator or to switch off the frequency generator or the invertor (C). <IMAGE>
