EVET 2120 - EV Power Electronics and Propulsion

3 sem hrs cr

EV Power Electronics and Propulsion covers the embedded power controls from inverters to variable frequency drives controlling the rotating magnetic fields in induction motors. Various hybrid design systems from range extenders to electric power systems assisting the internal combustion engine power will be discussed. Use of hydrogen fuel cells will also be covered as range extenders to direct power supply to the propulsion system. Prerequisite: MECH 1310   Corequisite: MECH 2320  

In rare and unusual circumstances, a course prerequisite can be overridden with the permission of the Department Lead for the discipline.
