Currently, switched reluctance machines (SRMs) have attracted the attention of the research community for electric vehicle (EV) applications due to their good performance at high speeds. This paper presents a new converter that doubles the negative demagnetization voltage for EV applications, so that, the provided converter is capable of reducing demagnetization time considerably with a new strategy. This method reduces the current commutation time and improves the average torque of the motor. Compared to the previous converters with the ability to increase the demagnetization voltage, the mentioned method significantly improves the efficiency of the motor at all speeds. This is due to the use of minimal electronic devices in the proposed topology. The mentioned method significantly increases the average torque and efficiency in the motor at all speeds, compared to the conventional asymmetric converter, due to the lack of additional electronic devices. This topology is very suitable for EV applications with multi-module battery structures. All operating modes of the proposed converter and simulation results will be described. As can be seen from the simulation results, the proposed converter improved efficiency and output torque significantly.
