“…In order to improve the performance of the SRM converter topology, many researchers have tried to find the solution to drive an SRM by a standard inverter [5][6][7][8][9][10][11][12]. All the existing novel designs can be divided into two groups: changing the structure or topology of the SRM and changing the excitation method.…”

“…By using two three-phase standard inverters, the new SRM can be driven, which corresponds also in fact to three single-phase H bridges. For the second group-changing the excitation-References [7,8] present a four-phase SRM converter with a different topology, with an extra DC-link current sensor and a single-current sampling resistance, resulting in four transistor-diode legs, but with a compromise of efficiency. The new design can contribute to fault diagnosing and decreasing the cost of SRM controller, and the main ideas were still the improvement of conventional asymmetric H-bridges.…”

This paper proposes a new driving method for switched reluctance motors (SRMs) using the standard full-bridge inverter. In spite of changing the internal structure of an SRM, the proposed method uses an extra ring structure circuit to make it possible for the inverter to drive the SRM. Next to the standard converter, a controllable DC source is needed. With theoretical analysis and calculation, the reference value of the circulating current in the ring structure was determined and the new method was proven via simulation. A comparison was made with the conventional method for driving an SRM: the asymmetric H-bridges. Also, the current studies were then made to confirm that the SRM could be controlled without lowering the performance of the machine. Experimental verification was also made under different conditions, as well as comparison with the simulation results.
