Mathematical Model of Two-Bridge Multi-Shouldered Adjustable Rectifier Unit Based on Transformer with Rotating Magnetic Field Equipped with Odd Section Count of Both Circular Windings

The paper presents a short review of new class semiconductor converters based using the transformer with rotating magnetic field which is profitably differs from well-known designs via full geometric, electric and magnetic symmetry. The paper itemizes basic types of semiconductor converters which could be built using new power core and also reveals application spheres of these converters. A special attention is paid to the two-bridge multi-shouldered adjustable rectifier, its electric schematic diagram is shown, primary features of its design are described, its mathematic model built using MATLAB Simulink software is presented along with few notes regarding it commented. An analytical approach to the mathematical modeling of electromagnetic processes which are responsible to the electric energy transformation event is shown, the approach which guarantees the mathematic modeling of rectifier electrical installation in general to be correct entirely. The results of modeling 12 kW rectifier are shown alongside with its adjusting characteristic, output voltage curves, energetic efficiency ratio and ripple factor are calculated for nominal power mode and partial power modes alike.
