Acoustic wave generation circuit has diode or diode module connected in parallel across HV capacitor

摘要

The circuit has a selectively discharged HV capacitor (22), connected in series with a coil (23) of an electromagnetic sound generator and a diode (24) or a diode module with at least 2 high current diodes, connected in parallel across the HV capacitor and biased in the blocking direction for the capacitor charging voltage.
