Abstract (en)
[origin: EP0702350A2] The control circuit has a charging stage for charging a capacitor (2) and a discharge stage in parallel with the latter, containing at least one HV switch (4) and the pulsed sound source (1). The discharge stage has a limiting circuit, for limiting the time duration of the electrical oscillation exhibited by the pulsed sound source, in response to the stored charge transferred from the capacitor upon closure of the switch. Pref. the limiting circuit is provided by a short-circuit loop (7, 8, 9) in parallel with the capacitor and the pulsed sound source, containing a second HV switch (7), with a trigger circuit for the switch operated after the limited time duration.
