The article investigates the switching processes in class D modulators for optimal control of active devices (transistors, triodes, tetrodes, etc.) in real conditions, to reduce power losses in them and non-linear distortions of the modulator output voltage, as well as more accurate determination of the devices efficiency. The presented mathematical model takes into account the inertia of the switching processes, the duration of the rise and fall fronts of voltage and current pulses, as well as losses in switching elements.
