DEVICE FOR AMPLIFICATION OF RADIATING HYDROACOUSTIC PATH Russian patent published in 2024 - IPC H03F3/00 

FIELD: amplification equipment.

SUBSTANCE: device for amplifying a radiating hydroacoustic path is proposed, comprising a control unit, a power supply unit made on a controlled power supply of the required power, device for interfacing on the input signal bus, which includes band-pass filters of the corresponding low-frequency, mid-frequency, high-frequency subranges, three power amplifiers: low-frequency power amplifier, medium-frequency power amplifier and high-frequency power amplifier, each of which includes corresponding modifications of preamplifiers, pulse-width modulator, key power amplifiers, diode adder, service power supply and matching device, as well as a switching unit, which includes switches for connecting the corresponding load from a number of radiators of LF, MF and HF subranges.

EFFECT: wider frequency band of the claimed device, higher energy efficiency by double increase of energy efficiency in the upper part of each of the frequency sub-ranges, ensuring uniformity of the amplitude-frequency response with change in the output voltage.
