The circuit includes a voltage multiplier circuit connected to receive a signal corresponding to a DC bus voltage level from a rectifier circuit. The voltage multiplier circuit includes first and second voltage storing circuits configured to each respectively store a voltage level corresponding to a first multiple of the DC bus voltage level (e.g., at least twice the DC bus voltage level). The voltage multiplier circuit further includes a peak voltage holding circuit connected to the first and second voltage storing circuits to accumulate a voltage level corresponding to a second multiple of the DC bus voltage level (e.g., at least four times the DC bus voltage level). The circuit further includes an ignition module having a transformer selectively connected by way of a switch to the voltage multiplier circuit through a primary winding to receive the voltage accumulated at the peak voltage holding circuit, and thereby generate an ignition pulse voltage applied to the lamp through a secondary winding of the transformer.
