Abstract: A procedure for analyzing, designing, and assessing audio power amplifier output stages operating in classes A, B, AB, G, and H with reactive loads is presented. The study considers steady-state sinusoidal analysis for BJT, IGBT, and MOSFET technologies. Electrical/mechanical/acoustical models of loudspeakers and enclosures are used whose parameters are obtained through the Thiele/Small model. An equivalent electrical thermal model for a transistor heatsink ambience system associated with instantaneous and average powers is used for designing the power stage. A MATLAB software has been developed, which provides considerable support to the designer for all phases required in the design of audio power amplifier output stages.
