Switched reluctance machines provide a feasible solution for automotive applications. However, a small and low cost power electronics driver is of interest for this purpose. This paper presents a control algorithm for a single-bus star-connected switched reluctance drive system. This algorithm enables the conventional Miller topology to control the phase currents in the multiphase excitation mode of operation. This control algorithm is introduced for motoring and generating modes of operation. The introduced algorithm is simulated under motoring and generating modes. Afterward, experimental measurements are illustrated to prove the practicality of the proposed concept.
