A transducer 13 is connected to the winding of the transistor 4.

Pulse generator operates as follows.

When a control pulse is applied to the thyristor 2, inductive storage device 5 is charged to the required amount of energy ,. When the required amount of energy is accumulated in the inductive accumulator 5, a control pulse is applied to the thyristor 12, a negative voltage is induced in the primary winding of the transformer 4, and the thyristor 2 is locked, stopping further accumulation in the inductive accumulator 5. To reduce the peak current during the charging The inductive storage device 5 parallel to it includes a capacitor 8. The energy stored in the inductive storage device 5 is discharged through the electrodes 7 and creates in the space between them an electric field for Impact on fishing objects „
