FIELD: amplifying and generator technology.
SUBSTANCE: invention relates to amplifying and generator technology, in particular to key power amplifiers of hydroacoustic radiator excitation signals with wide power control range. The technical result is achieved by means of a discrete reduction of the supply voltage in low-power modes at the nominal sawtooth voltage amplitude, while maintaining set OS depth and parametric stabilisation proportionality.
EFFECT: invention provides possibility to improve quality performance of signals amplified under discrete power level control conditions.
