Energy Efficient Motor Drives and Power Electronics for EV, HEV, and PHEV Applications     


I.D.# C1045Printable Description
Duration: 4 Days

Electric motor drives have emerged as one of the differentiating technologies in electric vehicles (EV), hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV). As a result, it is critical for engineers and technical decision-makers to understand the various energy-efficient motor drive technologies and how to apply them. Likewise, power electronics is one of the key technologies enabling the shift from conventional gasoline/diesel engine powered vehicles to electric vehicles (EVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs). Of particular importance are the power electronics converters used in EVs, HEVs, and PHEVs, which include rectifiers, unidirectional and bidirectional DC-DC converters, inverters, and battery chargers.

The first two days of this seminar begins with an introduction to the principle of power electronics followed by a thorough coverage of various converters. The unique aspects of power converters in EVs, HEVs, and PHEVs are addressed, including vehicle to grid technology and battery chargers. Distinctive characteristics of the operation of EV converters, such as uncontrolled rectification of permanent magnet motors, are covered in detail. Modeling and simulation of different power converters are demonstrated with hands on examples and hardware-in-the-loop concepts are briefly covered.

The second two-day module begins by defining energy-efficient motors and EV/HEV/PHEV motors. Following an in-depth study of induction motor drives, permanent magnet (PM) brushless motor drives, and switched reluctance (SR) motor drives, attendees will understand the core motor drive technology for EVs, HEVs and PHEVs. The course concludes with information on in-wheel motors, emerging motor technologies, and electric variable transmission (EVT) motor systems.
