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 3):
The arrangement of  claim 2 , wherein the comparator, switch, inductor and control logic regulator elements are duplicated with a signal input from the existing mixer output to an inverter, then applied to new comparators, the output diode cathodes being connected to increase current and reduce ripple to realize a two-phase multi-phase converter.
