FIELD: amplifier equipment.
SUBSTANCE: invention relates to the field of amplification and generator technology and can be used in hydroacoustic broadband power amplifiers. For this purpose, a class H amplifier with output voltage feedback is proposed, which provides power supply to a linear power amplifier from a series-connected high voltage of a key power amplifier and a low bipolar output galvanically isolated voltage of a high-frequency converter, which reduces residual voltages at linear gain links, especially when operating on a complex load with a very small active power factor.
EFFECT: increase in the energy efficiency of a class H amplifier when operating on a complex load.
