Abstract
A voltage transformer circuit for supplying ignition power to a spark plug includes a transformer, a primary circuit, and a secondary circuit. The primary circuit is coupled with the secondary circuit via the transformer in order that, when a transistor switch is closed, power is transmitted from the primary circuit into the secondary circuit. The primary circuit includes a discharge path, for demagnetizing the transformer when the transistor switch is open and via which power can be retransmitted from the secondary circuit for shortening the duration of an arc discharge, and the discharge path forms a demagnetizing current with a primary side of the transformer.
