Overview
abstract
Several component-minimized circuit topologies for single-phase to three-phase conversion are proposed. The proposed topologies employ fewer semiconductor devices and generate high-quality output voltages. A suitable modification to achieve an active input current shaping feature 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 to facilitate circuit design are presented. Selected results are verified experimentally on laboratory prototype converters.
