AB  - Switch-mode power audio amplifiers, also known as class-D, have become the conventional choice for high power applications. This paper presents the considerations for designing a high power audio amplifier power stage. This includes an overview of loss mechanism including reverse recovery losses that are increasingly important at higher output powers. A 4 kW prototype amplifier is implemented. Absolute maximum ratings shows up to +/- 190 V output voltage swing and 6.5 kW for sine wave burst. THD+N levels go down to 0.003% for 100 Hz and are generally below 0.1% up to clipping at 4 kW in a 4 O load.
