Abstract:
An AC capable power amplifier arrangement is realized that includes a buck converter with a power inductor, two buck switches, and alternately a buck-boost converter using four switches, each driving an output polarity steering set of four switches. The polarity steering switches convey the converter output current to output terminals that connect to a load with a capacitor connected in parallel. A differential receiver is connected to the output terminals to provide negative feedback. A mixer receives an input voltage signal, an output of the differential receiver, and output from a triangle wave generator. A set of two comparators for buck amplifier conversion, or four comparators for buck-boost amplifier conversion, each receives an output of the mixer. Each of the comparators produces a respective output for driving the converter switches through simple steering logic interfaces between the comparators, the converter components and a polarity steering output stage.

Claim (Index 4):
The arrangement of  claim 2 , wherein the DC voltages applied to buck comparators are set apart from the DC bias point of the input signal at levels slightly smaller than the peak to peak amplitude of the output of the triangle wave oscillator so as to work with the output of the triangle wave oscillator to emulate low duty cycle class A-D amplifier modulation in the output polarity steering switches when coupled to the DC regulator architecture.
