FIELD: physics.
SUBSTANCE: invention relates to ultrasonic equipment and can be used for ultrasonic treatment of materials. The apparatus has electromagnetic eddy current inductors (1) connected through thyristor switches (2) with an electrodischarge current source. The electrodischarge current source has a step-up transformer (3), a rectifier (4) and a storage capacitor (5). Control electrodes of the thyristor switches (2) are connected to a commutator switch (6) which is connected to an electric pulse generator (7).
EFFECT: wide range of frequencies of excited oscillations.
