Abstract

Die Erfindung betrifft die Verbesserung einer Ansteuerschaltung für Hochleistungsimpulsschallquellen (2). Einem von einem Stoßkondensator (2) über einen Hochspannungsschalter (4) zur Impulsschallquelle führenden Entladekreis ist eine Begrenzerschaltung, z.B. ein Kurzschlußkreis (7,8,9) zugeordnet. Diese begrenzt die Zeitdauer der von der im Stoßkondensator (2) gespeicherten Ladung nach dem Schließen des ersten Hochspannungsschalters (4) an der Impulsschallquelle (1) erzeugten elektrischen Schwingung auf einen bestimmten Wert, so daß die elektrische Erregung und damit der mechanisch elektrische Verschleiß auf das zur Abstrahlung des Druckpulses erforderliche Minimum reduziert werden.

The invention relates to the improvement of a control circuit for high-power pulse sound sources (2). A discharge circuit, for example a short circuit (7, 8, 9), is assigned to a discharge circuit leading from a surge capacitor (2) via a high-voltage switch (4) to the pulse sound source. This limits the duration of the electrical oscillation generated by the charge stored in the surge capacitor (2) after the first high-voltage switch (4) is closed at the pulse sound source (1), so that the electrical excitation and thus the mechanical-electrical wear on the minimum required to emit the pressure pulse can be reduced.
