Abstract
A ballast that comprises a DC-DC converter, a DC-AC converter, a lighting voltage generator and a control unit. A difference in voltage between input terminals of the lighting voltage generator is generated by a voltage step-up circuit of the 'self-boosting' type from a DC voltage supplied by the DC-DC converter and an auxiliary voltage source V. The ballast makes it possible to obtain a voltage level Vthat is equal to twice a first voltage level Vincreased by the auxiliary voltage V
