A step-up converter and an ignition system with a step-up converter are proposed, which permit better automated production and reduced electrical insulation measures by way of a step-up converter having the following structure: - a transformer (3) with a primary coil (31) and a secondary coil (32) galvanically separated from the primary coil, wherein - the secondary coil (32) is wound in multiple layers and - the primary coil (31) is wound coaxially with respect to the secondary coil (32) over an outermost layer of the secondary coil (32), wherein - a first electrical terminal (32a) of the secondary coil (32) branches off an innermost layer of the secondary coil (32) , characterized in that - the first electrical terminal (32a) of the secondary coil (32) is designed for electrical connection to a high-voltage terminal for the spark gap. |
