Presented is a driving circuit for multiple discharge lamps, including a plurality of transformers having a plurality of primary windings and secondary windings, in which each secondary winding is connected in series with a resonance circuit and each resonance circuit is coupled to a discharge lamp. The driving circuit further includes an additional resonance inductor coupled to the primary side of the transformers for increasing the resonance inductance of the resonance circuit and allowing the resonance inductance of the resonance circuit to be modulated in response to the variation of the impedance of the discharge lamp or the variation of the impedance of the resonance capacitor of the resonance circuit.
