Single conversion audio amplifier and DC-AC converters with high performance and low complexity control scheme

Abstract

This paper proposes a novel control topology for a mains isolated single conversion audio amplifier and DC-AC converters. The topology is made for use in audio applications, and differs from prior art in terms of significantly reduced distortion as well as lower system complexity. The topology can be useful in a wide range of DC-AC applications such as motor drives or UPS systems requiring mains isolation as well.
