Abstract
An ignition system employing a piezoelectric transformer having a drive side and an output side. The ignition system further includes circuit elements in electronic communication with the output side that tune output impedance in series with a breakdown gap to optimize power flow from the transformer to the breakdown gap after breakdown and a timing control circuit in electronic communication with the drive side that meters post-breakdown energy delivered to the breakdown gap by timing the duration of post-breakdown power flow.
