"A simplified explanation of the operation of the Sunfire amplifier is that the DC output of a conventional power supply is pulse-width-modulated by the audio signal. The supply delivers narrow pulses when the signal level is low, increasing the pulse width linearly with signal level. The result is that most of the amplifier's output voltage comes from the power supply, leaving only about 6 volts across the output transistors. The action of the switching system (the "tracking downconverter") is analogous to that of a transformer, converting a high voltage at low current to a lower voltage at higher current, but without significant power loss or heat generation."
