description: The final qualifying work is devoted to the study of a switch power amplifier with improved energy characteristics for use as part of a sonar transmission path. The object of the study is a Class D amplifier used to excite a hydroacoustic transducer. The subject of the study is the dynamic processes in the half-bridge cascade and the energy characteristics of the circuit of the terminal cascade of a switch power amplifier associated with the switching times of switch elements and the resulting high-frequency oscillation. The purpose of this work is to reduce the dynamic energy losses on switching by selecting the control parameters of switch elements, as well as increasing reliability by reducing the amplitude of high-frequency oscillations through the use of damping circuits. Based on the study of a switch power amplifier with improved energy characteristics, recommendations have been developed on the choice of transistor control modes and damping circuit parameters to reduce energy losses in terminal stages and increase the reliability of Class D broadband amplifiers. Terminological features of the subject area are taken into account and software tools are used to solve problems. Specialized program-mathematical software MicroâCap was used.
