This paper presents studies of Low-Frequency Power Amplifier class D with operational amplifiers and transistors. Their features have been presented and а selected circuit is described. The obtained results have been presented using MultiSIM software – oscillograms in specific nodes of the circuit, amplitude-frequency and phase-frequency responces and their parameters, and results of carried out Fourier and Parameter Sweep analyzes. Simulation results could be used in carrying out the optimization of its characteristics and qualitative parameters, as well as present and expected practical results. The results of performed experimental studies of implemented low-frequency power amplifier class D are presented also.
