Design and development of a high-efficiency electric drive train for hybrid electric vehicle applications

It is a well known fact that the major cost in modern hybrid electric vehicles (HEV) is incurred in developing and managing the energy storage system and on-board power generation. An effective way to economise HEV operation is to design an optimally efficient electric drive train. Keeping this fact in mind, the major goals of this project are two-fold. The first goal is to model the noteworthy DC/AC traction inverter and motor losses (efficiencies) over typical city and highway driving schedules. A brush-less DC (BLDC) motor will be modeled and designed for propulsion. This leads to the subsequent key target of the proposed project, which includes the design and implementation of a novel hybrid control strategy, in order to maximize the electric drive train efficiency.
