The purpose of this design project was to develop an energy efficient motor controller for use in the Prototype Battery Electric Vehicle division of Shell Eco-marathon (SEM). The controller, an imperative component of the overall vehicle, is to be used to drive both alternating current (AC) and direct current (DC) electric motors, based upon the design decisions of Supermileage Systems Enterprise (SSE). The controller acts as a single-quadrant buck converter for a DC drive and a three-phase inverter for the AC drive. The project focused on the optimization of controller hardware, component selection, printed circuit board (PCB) layout, and software control methods to operate at the maximum feasible efficiency to drive the vehicle.
