A circuit for providing a follow-on current between the electrodes of a traveling spark ignitor after an initial break down between the electrodes has occurred is disclosed. The circuit may include first and second portions which, respectively, provide first and second voltages to the ignitor. The first portion may be a conventional ignition circuit. The second portion provides the follow-on current. The second portion may provide the follow-on current as a single discharge or as a multi-stage discharge.
