Abstract :
In this article the equivalent circuit of class D amplifier with elements that create and distribute conducted electromagnetic interferences is suggested. SPICE simulation of class D amplifier inclusive parasitic parameters with connection to LISN have been realized. The results of computer simulation with experimental data of the interferences measuring are compared. The theoretical and experimental analysis of the influence of input signal amplitude on the noise level of class D amplifiers are confirmed. Simulation results are generally coincide with the measurement ones.
