to Three-phase Converter Variable Frequency Output

In this paper, several new component minimized circuit topologies for single-phase to three-phase conversion are proposed. The proposed topologies employ fewer semiconduc- tor devices and generate high-quality output voltages. Suitable modification to achieve active input current shaping feature is also illustrated in detail. Analysis and simulation of the proposed schemes is carried out to show the high-performance features. Suitable guides for the selection of filter components and for facilitating circuit design is presented. Finally, selected results are verified experimentally on laboratory prototype converters.
