Feasibility of power electronic converters for low-voltage (42 V) SRM drives in mildly hybrid electric traction systems

The more electric car (MEC) concept emphasizes utilizing electrical power to drive more automotive conventional systems and to facilitate new introduced luxury loads. Improving fuel economy, emissions, reliability, and comfort are the main motivations towards the MEC concept, which necessitates going to a higher system voltage such as the proposed 42 V. This paper presents that the 42 V system is also feasible for driving current intensive switched reluctance motor (SRM) drives as the traction loads in mildly hybrid electric cars.
