Abstract Details

2018, Master of Science in Engineering, University of Akron, Electrical Engineering.
In this thesis, a switched reluctance machine (SRM) with a new winding configuration and a novel power converter design is presented. The new winding topology along with the power converter are developed to improve the machine efficiency by exciting a portion of the phase windings at high speeds. The new topology helps to overcome the effects of the high back EMF voltage (Electromotive Force) and improve the torque characteristics of SRMs. The phase windings are split into two interconnected windings, each with a different number of turns. The two windings act as a transformer due to the magnetic coupling between them. To drive the split winding machine with a different number of turns at different speed levels, the H-bridge converter was improved by adding one extra switch on each leg. The extra switches are only used at high speed operation to reduce the number of turns. At high speed operations, the proposed set-up using only one portion of the winding, pushes higher phase currents. The new winding configuration and extra switch converter topology drive the proposed machine efficiently over a variable speed range. In addition, the proposed work improves the torque characteristic of the machine at both medium and high-speed levels by reducing the number of turns which, as mentioned above, enables the application of higher currents to the phase. The proposed design is investigated using Finite Element Analysis (FEA) circuit simulations on a case study SRM. The new power converter and its associated control algorithm have been tested experimentally. The experimental and simulation results for both full and split winding, SRMs are compared.
