Economic single-phase to three-phase converter topologies for fixed and variable frequency output

Abstract

Several component-minimized circuit topologies for single-phase to three-phase conversion are proposed. The topologies employ fewer semiconductor devices and generate high-quality output voltages. Suitable modification to achieve active input current shaping is illustrated in detail. Analysis and simulation of the proposed schemes are carried out to show the high-performance features. Suitable guidelines for the selection of filter components and for facilitating circuit design are presented. Selected results are verified experimentally on laboratory prototype converters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
