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.

Tuned power ignition system

The present invention comprises a piezoelectric transformer having substantially improved performance. The piezoelectric element is composed of a single crystal of a relaxor ferroelectric piezoelectric material. This element is coupled to input and output electrodes. The element vibrates mechanically in response to an input signal, which causes an output signal to be generated at the output electrodes. Improved power transmission is observed despite the reduced mechanical Q of the single crystal material, because the coupling and dielectric strength of the material are improved relative to polycrystals.
